Description
Technical Field
[0001] The present application relates to the technical field of electronic atomization devices, and more specifically, to an oil prevention structure and an aerosol generating device. Background Art
[0002] An aerosol generating device can form an aerosol by heating an aerosol medium. The atomization process is simple, convenient to operate, and does not produce residual substances, etc. Generally, a microphone is set in the aerosol generating device to sense the air pressure, so as to control the heating of the atomization medium through the air pressure, making the atomization process more intelligent.
[0003] Currently, there is usually only one airway in the aerosol generating device. The top of the airway is a mouthpiece, the middle section of the airway is located in the oil cup and is internally provided with an atomization core, and the capacitive microphone is connected to the bottom end of the airway. Since the main airway is in a high-temperature environment during the suction process, condensate is likely to form in the airway when not in suction. The condensate and the aerosol medium are likely to flow into the mouth of the microphone through the airway, affecting the sensitivity of the microphone operation. In severe cases, the microphone is directly damaged, resulting in the product having no suction function and the microphone starting automatically, thereby affecting the product performance and the user experience. Summary of the Utility Model
[0004] The technical problem to be solved by the embodiments of the present application is that the condensate and the aerosol medium are likely to flow into the mouth of the microphone through the airway, affecting the sensitivity of the microphone operation. In severe cases, it is directly damaged, resulting in the product having no suction function and the microphone starting automatically, thereby affecting the product performance and the user experience.
[0005] To solve the above technical problems, the embodiments of the present application provide an oil prevention structure, which adopts the following technical solutions, including:
[0006] A housing member for housing the microphone, and the housing member is provided with an airway so that the microphone can communicate with the atomization assembly through the airway;
[0007] An oil prevention cover is provided on the housing member. The oil prevention cover is provided with a first ventilation hole, and the first ventilation hole is respectively communicated with the airway and the atomization assembly;
[0008] Wherein, the airway includes a receiving hole provided on the housing member and a first communication hole for communicating the microphone and the receiving hole. The first communication hole is provided between the receiving hole and the microphone. In the vertical direction, the lower end surface of the first communication hole is higher than the lower end surface of the receiving hole, so that the condensate and the aerosol medium entering the airway from the first ventilation hole are drained into the receiving hole.
[0009] Furthermore, the air passage also includes a groove arranged on the accommodating part and a second connecting hole connecting the groove and the accommodating hole. In the vertical direction, the first vent hole, the groove, the second connecting hole and the accommodating hole are arranged in sequence from high to low.
[0010] Furthermore, the diameter of the accommodating hole gradually increases in a direction away from the microphone, so that the accommodating hole has a tapered hole structure.
[0011] Furthermore, the accommodating hole is provided with oil-absorbing cotton at one end thereof facing away from the microphone.
[0012] Furthermore, the aperture of the first communicating hole is smaller than the minimum aperture of the accommodating hole, so that a step surface facing away from the microphone is formed between the first communicating hole and the accommodating hole.
[0013] Furthermore, the oil-proof cover is also provided with a connecting channel connecting the first vent hole and the groove.
[0014] Furthermore, the axis of the first vent hole, the axis of the accommodating hole and the axis of the first connecting hole are arranged in a horizontal direction, and the axis of the second connecting hole and the connecting channel are arranged in a vertical direction.
[0015] Further, in the horizontal direction, the groove is offset along the connecting channel toward the second communicating hole.
[0016] Furthermore, it also includes a bracket, on which is provided an installation cavity for accommodating the accommodating member and a plug for installing the oil-proof cover, and after installation, the oil-proof cover is located at the upper end of the accommodating member.
[0017] In order to solve the above technical problems, an embodiment of the present application further provides an aerosol generating device, which adopts the following technical solution: comprising an atomizing component and the oil-proof structure, wherein the atomizing component is arranged at the upper end of the oil-proof structure.
[0018] Compared with the prior art, the embodiments of the present application mainly have the following beneficial effects: since the lower end surface of the first connecting hole is higher than the lower end surface of the accommodating hole in the vertical direction, the present application ensures that the condensate and the aerosol medium are drained and retained in the accommodating hole of the airway, and will not flow into the microphone head through the first connecting hole or accumulate at the microphone head, so that the microphone head can maintain normal operation, enhance the oil-proof function of the microphone head, solve the problem of damage and self-starting of the microphone head caused by condensate and aerosol medium, improve product safety and user experience, and greatly extend the product service life.

Detailed implementation manners
[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the art to which this application belongs; the terms used in the description of the embodiments in this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the description and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the description and claims of this application or the above drawings are used to distinguish different objects and are not used to describe a specific order.
[0031] References to "embodiments" in this document mean that the specific features, structures, or characteristics described in connection with the embodiments can be included in at least one embodiment of the present application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.
[0032] To enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.
[0033] Please refer to Figures 1 to 7 As shown, the embodiments of the present application provide an oil-proof structure, including:
[0034] A housing member 1 for housing a microphone 2, and the housing member 1 is provided with an air passage 100 so that the microphone 2 can communicate with an atomization assembly through the air passage 100;
[0035] An oil-proof cover 3 is disposed on the housing member 1. The oil-proof cover 3 is provided with a first ventilation hole 31, and the first ventilation hole 31 communicates with the air passage 100 and the atomization assembly respectively;
[0036] Wherein, the air passage 100 includes a receiving hole 11 provided on the housing member 1 and a first communication hole 12 for communicating the microphone 2 and the receiving hole 11. The first communication hole 12 is disposed between the receiving hole 11 and the microphone 2. In the vertical direction, the lower end surface of the first communication hole 12 is higher than the lower end surface of the receiving hole 11, so that the condensate and aerosol medium entering the air passage 100 from the first ventilation hole 31 are drained into the receiving hole 11.
[0037] Since the lower end surface of the first communication hole 12 is higher than the lower end surface of the receiving hole 11 in the vertical direction, it is ensured that the condensate and aerosol medium are drained and retained in the receiving hole 11 of the air passage 100, and will not flow over the first communication hole 12 into the microphone 2 or accumulate at the microphone 2, enabling the microphone 2 to work normally, enhancing the oil-proof function of the microphone 2, solving the problems of damage and self-start of the microphone 2 caused by condensate and aerosol medium, improving the product use safety and user experience effect, and greatly extending the product service life.
[0038] As shown in the Figure 2 to the Figure 6As shown, further, the air duct 100 further includes a groove 13 provided on the accommodating member 1 and a second communication hole 14 communicating the groove 13 and the accommodating hole 11. In the vertical direction, the first ventilation hole 31, the groove 13, the second communication hole 14, and the accommodating hole 11 are arranged from high to low in sequence. This makes it difficult for the generated condensate and aerosol medium to enter the microphone 2 from the air duct 100. Even if they enter the air duct 100, due to the height difference, they will enter and remain in the accommodating hole 11 along the groove 13 and the second communication hole 14, and will not flow over the first communication hole 12 into the microphone 2 and accumulate at the microphone 2. This can enable the microphone 2 to work normally, enhance the oil-proof function of the microphone 2, solve the problems of damage and self-activation of the microphone 2 caused by condensate and aerosol medium, improve the product use safety and user experience effect, and greatly extend the product service life.
[0039] Furthermore, the vertical direction refers to the direction perpendicular to the axis of the first ventilation hole 31, that is, the axial direction of the second communication hole 14, and the horizontal direction refers to the axial direction of the first ventilation hole 31.
[0040] As shown in the appendix Figure 2 to the appendix Figure 6 As shown, further, the aperture of the accommodating hole 11 gradually increases in the direction away from the microphone 2, so that the accommodating hole 11 is a tapered hole structure. The structure of the tapered hole can make the condensate and aerosol medium flowing into the accommodating hole 11 flow in the direction away from the microphone 2 under the action of its own gravity, so that the condensate and aerosol medium remain in the accommodating hole 11, prevent them from flowing into the microphone 2 and accumulating at the microphone 2, enhance the oil-proof function, and solve the problems of damage and self-activation of the microphone 2 caused by condensate and aerosol medium.
[0041] As shown in the appendix Figure 2 to the appendix Figure 4 As shown, further, an oil-absorbing cotton 4 is further provided at one end of the accommodating hole 11 facing away from the microphone 2. The oil-absorbing cotton 4 can absorb the condensate and aerosol medium flowing into the accommodating hole 11, further increasing the capacity of the accommodating hole 11 to retain the condensate and aerosol medium, preventing the condensate and aerosol medium flowing into the accommodating hole 11 from being too much and causing backflow into the microphone 2, and solving the problems of damage and self-activation of the microphone 2 caused by condensate and aerosol medium.
[0042] As shown in the appendix Figure 2 to the appendix Figure 6As shown, further, the aperture diameter of the first communication hole 12 is smaller than the minimum aperture diameter of the accommodation hole 11, so that a stepped surface 111 facing away from the direction of the microphone 2 is formed between the first communication hole 12 and the accommodation hole 11. The stepped surface 111 can further increase the difficulty of the condensate and aerosol medium in the accommodation hole 11 flowing back into the microphone 2, and at the same time further increase the capacity of the accommodation hole 11 to retain the condensate and aerosol medium, solving the problems of damage and self-activation of the microphone 2 caused by the condensate and aerosol medium.
[0043] As shown in the attached Figure 2 to the attached Figure 7 As shown, further, a connection channel 32 connecting the first ventilation hole 31 and the groove 13 is also provided on the oil-proof cover 3. The axis of the first ventilation hole 31, the axis of the accommodation hole 11, and the axis of the first communication hole 12 are arranged in the horizontal direction, and the axes of the second communication hole 14 and the connection channel 32 are arranged in the vertical direction. It is convenient for the condensate and aerosol medium to flow into the accommodation hole 11 after passing through the connection channel 32, the groove 13, and the second communication hole 14 in sequence, playing a guiding role for the condensate and aerosol medium.
[0044] Furthermore, the oil-absorbing cotton 4 and the microphone 2 are correspondingly arranged on both sides of the accommodation hole 11. After the condensate and aerosol medium enter from the first ventilation hole 31 or are generated at the first ventilation hole 31, they pass through the connection channel 32, the groove 13, and the second communication hole 14 in sequence and then enter the accommodation hole 11. Since the accommodation hole 11 is a conical hole structure, the condensate and aerosol medium flowing into the accommodation hole 11 flow in the direction away from the microphone 2 under the action of their own gravity, so that the condensate and aerosol medium stay at the oil-absorbing cotton 4 and are absorbed by it, preventing them from flowing into the microphone 2 and accumulating at the microphone 2, enhancing the oil-proof function, and solving the problems of damage and self-activation of the microphone 2 caused by the condensate and aerosol medium.
[0045] As shown in the attached Figure 3 to the attached Figure 6 As shown, further, in the horizontal direction, the groove 13 is offset along the connection channel 32 towards the direction of the second communication hole 14. It is convenient to drain the condensate and aerosol medium into the accommodation hole 11. At the same time, in the vertical plane, the groove 13 is inclined along the connection channel 32 towards the direction of the second communication hole 14, so that the condensate and aerosol medium can flow down into the accommodation hole 11 as soon as possible and be absorbed by the oil-absorbing cotton 4, preventing the condensate and aerosol medium from blocking the air passage 100 and affecting suction.
[0046] As shown in the attached Figure 1 to the attached Figure 4As shown in the figure, further, it further includes a bracket 5. An installation cavity 51 for accommodating the accommodating member 1 and a plug post 52 for installing the oil-proof cover 3 are provided on the bracket 5. After installation, the oil-proof cover 3 is located at the upper end of the accommodating member 1. The structure is simple and easy to install and disassemble.
[0047] Furthermore, a receiving cavity 53 is also provided on the bracket 5. The receiving cavity 53 can also retain the condensate and aerosol medium that fall from the atomization assembly 200 above the bracket 5. The plug post 52 protrudes and is arranged in the receiving cavity 53. Therefore, after installation, the oil-proof cover 3 further protrudes in the receiving cavity 53, increasing the storage capacity of the receiving cavity 53, preventing a small amount of condensate and aerosol medium from accumulating in the receiving cavity 53 and reaching the first ventilation hole 31, which may cause a large amount of condensate and aerosol medium to enter the air duct 100 through the first ventilation hole 31, resulting in accidents such as blocking the air duct 100 or drowning the microphone 2. It greatly reduces the amount of condensate and aerosol medium entering the air duct 100 from the first ventilation hole 31, enhances the oil-proof function, solves the problems of damage and self-activation of the microphone 2 caused by condensate and aerosol medium, and can also prevent the condensate and aerosol medium from blocking the air duct 100, avoiding affecting the normal suction of users. At the same time, the opening of the first ventilation hole 31 faces the side wall of the receiving cavity 53, which can prevent the condensate and aerosol medium that fall from the atomization assembly 200 above the bracket 5 from directly falling into the first ventilation hole 31 and then directly entering the connection channel 32, further reducing the amount of condensate and aerosol medium entering the air duct 100 from the first ventilation hole 31 and further enhancing the oil-proof function.
[0048] Furthermore, the accommodating member 1 is made of silica gel material. After installation, the accommodating member 1 is hermetically connected to the inner wall of the installation cavity 51, so that the first ventilation hole 31 is hermetically connected to the air duct 100 and the atomization assembly respectively, preventing air leakage and avoiding affecting the normal operation of the microphone 2. The protruding height of the plug post 52 is above 1.5 mm. A first installation groove for the oil-absorbing cotton 4 is also provided in the installation cavity 51, and a second installation groove 15 for installing the microphone 2 is provided in the accommodating member 1. During installation, first rivet the oil-proof cover 3 on the plug post 52, then install the oil-absorbing cotton 4 in the first installation groove, then install the accommodating member 1 in the installation cavity 51, and finally install the microphone 2 in the second installation groove 15. The structure is simple, the installation is convenient and fast, and the installation position of the microphone 2 can be unrestricted, and the cooperative installation with other mechanisms is more flexible.
[0049] Please refer to Figures 8 to 9As shown in the figure, based on the above oil-proof structure, an embodiment of the present application further provides an aerosol generating device, which includes an atomization component 200 and the oil-proof structure, and the atomization component 200 is arranged at the upper end of the oil-proof structure. Since the axis of the first ventilation hole 31 and the airway 100 are arranged to intersect with each other and the first ventilation hole 31 and the microphone 2 are arranged in a staggered manner, it is ensured that the condensate and the aerosol medium only remain in the airway 100 and will not flow into the microphone 2 through the airway 100 or accumulate at the microphone 2, enabling the microphone 2 to work normally, enhancing the oil-proof function of the microphone 2, solving the problems of damage and self-activation of the microphone 2 caused by the condensate and the aerosol medium, improving the safety of product use and the user experience effect, and greatly extending the service life of the product.
[0050] When the user sucks, the outside air sequentially passes through the microphone 2, the first communication hole 12, the accommodation hole 11, the second communication hole 14, the groove 13, the connection channel 32 and the first ventilation hole 31, and then enters the atomization component 200. The atomization component 200 generates aerosol, and finally the user inhales the aerosol from the mouthpiece.
[0051] Furthermore, of course, the oil-proof structure can also be set as an independent double-airway structure, that is, the main airway and the microphone airway. By separating the main airway from the microphone airway, the main airway can communicate with the atmospheric pressure through the microphone airway, and the condensate and the aerosol medium will not enter the microphone airway, which can achieve the same oil-proof effect as the present application. However, compared with the oil-proof structure of the present application, the independent double-airway structure is complex, occupies a large structural space, and has a high manufacturing cost. Therefore, the present application not only has a good oil-proof effect, but also has a simple structure, ingenious design, and low manufacturing cost.
[0052] Obviously, the embodiments described above are only a part of the embodiments of the present application, rather than all the embodiments. The accompanying drawings show the preferred embodiments of the present application, but do not limit the patent scope of the present application. The present application can be implemented in many different forms. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure content of the present application more thorough and comprehensive.
