Description

Technical Field

[0003] When using an electronic atomizer device, the user uses his mouth to inhale into the airflow channel, thereby generating airflow in the airflow channel. The activated airway is affected by the airflow channel and generates negative pressure, which in turn causes the conductive film of the microphone to deform and the capacitance of the microphone to change, thereby controlling the operation of the atomizer component.

[0014] In some embodiments of the present application, the pressure relief air duct includes an air inlet section, and the air inlet section is communicated with the first end of the starting air duct;

[0015] A pressure relief groove is recessed on the side of the sealing block facing away from the buffer chamber, and one side of the pressure relief groove is connected to the first end of the starting air duct. The shell assembly also includes a mounting plate, which is connected to the sealing block and covers the notch of the pressure relief groove to enclose and form the air inlet section.

[0016] In some embodiments of the present application, the shell assembly is further provided with an air collecting duct, one end of the air collecting duct is connected to the air flow channel, and the other end of the air collecting duct is respectively connected to the starting air channel and the pressure relief air channel, so that the starting air channel and the pressure relief air channel are both connected to the air flow channel through the air collecting duct.

[0017] In some embodiments of the present application, the starting air channel includes a mounting section, the mounting section being located between the first end of the starting air channel and the second end of the starting air channel and being used for mounting the microphone;

[0018] The mounting plate is provided with a first through hole along its thickness direction, and the first through hole is connected to the first end of the starting air duct.

[0023] The electronic atomization device provided in the embodiment of the present application has a built-in microphone in its starting airway, which will produce a certain resistance to the flow of gas. Therefore, under the same conditions, the gas will preferentially flow into the airflow channel from the pressure relief airway with less resistance. The gas entering the starting airway from the air inlet flows into the pressure relief airway through the first end, and then flows into the airflow channel through the pressure relief airway. Since the gas does not flow into the airflow channel through the second end, the gas bypasses the microphone. When the electronic atomization device is held by a person or subjected to external force, causing a slight change in the air pressure in the starting airway, the gas flow caused by the slight air pressure change can be preferentially discharged to the airflow channel through the pressure relief airway to reduce or avoid the gas flowing through the microphone, so as to reduce the influence of the slight air pressure change on the conductive film of the microphone, thereby avoiding the self-starting of the electronic atomization device. It can be seen that the technical solution of the present application can reduce the influence of the slight air pressure change on the conductive film of the microphone when the air pressure in the starting airway changes slightly, so as to avoid the self-starting of the electronic atomization device.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0040] The embodiment of the present application proposes an electronic atomization device 100, please refer to Figures 1 to 5 In an embodiment of the present application, the electronic atomization device 100 includes a shell assembly 10, an atomization assembly 20 and a microphone 30. The microphone 30 is electrically connected to the atomization assembly 20 to control the operation of the atomization assembly 20. The shell assembly 10 is provided with an air flow channel 11, a starting air channel and a pressure relief air channel 13.

[0041] The outer contour shape of the housing assembly 10 is varied. The housing assembly 10 can be in the shape of a long rod or a rectangular box. It should be noted that the housing assembly 10 is usually composed of multiple parts, wherein the airflow channel 11, the starting air channel, and the pressure relief air channel 13 refer to air channels for air flow, and do not specifically refer to the internal structure of a certain part. They can be formed by multiple parts together. For example, the airflow channel 11 includes a first section, a second section, and a third section in sequence along the direction of airflow. The first section, the second section, and the third section can be formed by different parts respectively, and then spliced ​​and connected together.

[0042] The airflow channel 11 has an airflow inlet 111 and an airflow outlet 112, with an atomizer assembly 20 mounted on the end of the airflow channel 11 away from the airflow outlet 112. The starting air channel has a built-in microphone 30, and an air inlet 121 is provided at the first end of the starting air channel, and the second end of the starting air channel is connected to the airflow channel 11. The pressure relief air channel 13 is connected to the first end of the starting air channel at one end and to the airflow channel 11 at the other end.

[0043] The airflow outlet 112 and the airflow inlet 111 of the airflow channel 11 are usually exposed on the outer surface of the shell assembly 10, wherein the airflow outlet 112 is for the user to directly use the mouth to inhale. Of course, in other examples, a mouthpiece can also be provided on the surface of the shell assembly 10 to communicate with the airflow outlet 112, and the airflow inlet 111 allows external gas to enter the airflow channel 11. Similarly, the airflow inlet 111 can also be connected to the outside through a filter.

[0044] The atomizer assembly 20 can be installed in the airflow channel 11 in a variety of ways, such as snap-on or plug-in. The atomizer assembly 20 has a built-in atomizer chamber. The atomizer assembly 20 uses electrical energy to atomize the atomized liquid in the atomizer chamber to form an aerosol. Since the atomizer assembly 20 is installed in the airflow channel 11, the aerosol can flow along the airflow channel 11 under the drive of an external force.

[0045] It is understood that since the second end of the starting airway is connected to the airflow channel 11, when airflow is generated in the airflow channel 11, the airflow in the airflow channel 11 disturbs the gas in the starting airway, thereby generating a negative pressure in the starting airway. The microphone 30 can be used to detect changes in air pressure. When the air pressure changes, the conductive film of the microphone 30 deforms, causing the microphone 30 to produce a change in capacitance. The microphone 30 can then transmit an electrical signal to the atomizer assembly 20 to control the operation of the atomizer assembly 20.

[0046] When the electronic atomization device 100 is used by a user, the user inhales the airflow outlet 112 of the airflow channel 11 to drive external gas into the airflow channel 11 from the airflow inlet. The microphone 30 detects the change in air pressure by activating the airway, thereby controlling the operation of the atomization component 20. At the same time, when the gas flows through the atomization component 20, the gas will carry away the aerosol and be discharged from the airflow outlet 112 for the user to inhale.

[0047] The starting air duct of the electronic atomization device 100 provided in the embodiment of the present application is equipped with a built-in microphone 30, which will generate a certain resistance to the gas flow. Therefore, under the same conditions, the gas will preferentially flow into the air flow channel 11 from the pressure relief air duct 13 with smaller resistance. The gas entering the starting air duct from the air inlet 121 flows into the pressure relief air duct 13 through the first end, and then flows into the air flow channel 11 through the pressure relief air duct 13. Since the gas does not flow into the air flow channel 11 through the second end, the gas bypasses the microphone 30. When the electronic atomization device 100 is held by a person or subjected to external force, causing a slight change in the air pressure in the starting air duct, the gas flow caused by the slight air pressure change can be preferentially discharged to the air flow channel 11 through the pressure relief air duct 13, so as to reduce or avoid the gas flowing through the microphone 30, so as to reduce the influence of the slight air pressure change on the conductive film of the microphone 30, thereby avoiding the self-starting of the electronic atomization device 100. It can be seen that the technical solution of the present application can reduce the impact of slight air pressure changes on the conductive film of the microphone 30 when the air pressure in the starting airway changes slightly, so as to avoid the electronic atomization device 100 from self-starting.

[0048] In some examples, such as Figure 3 As shown, the distance from the connection point between the pressure relief air channel 13 and the first end of the starting air channel to the air inlet 121 is defined as a first distance, and the distance from the microphone 30 to the air inlet 121 is defined as a second distance. The first distance is smaller than the second distance.

[0049] This configuration aims to reduce the resistance of gas flowing from the air inlet 121 to the pressure relief airway 13 by optimizing the specific structure of the electronic atomization device 100 , so that the gas flow caused by slight air pressure changes can be better discharged to the airflow channel 11 .

[0050] In some examples, such as Figures 1 to 3 As shown, the housing assembly 10 is further provided with a buffer chamber 14 and a pressure relief hole 141 communicating with the buffer chamber 14 , and the air inlet 121 is communicated with the buffer chamber 14 to communicate with the outside through the buffer chamber 14 .

[0051] This arrangement is intended to buffer the impact of sudden changes in external air pressure on the starting airway through the buffer chamber 14. When external wind blows towards the electronic atomization device 100, the buffer chamber 14 can reduce the air intake of the air inlet 121.

[0052] In some examples, such as Figure 3As shown, the pressure relief hole 141 is located in the extension direction of the first end of the starting airway and is offset from the air inlet 121. This arrangement is intended to further reduce the impact of sudden changes in external air pressure on the starting airway. The airflow entering the buffer chamber 14 through the pressure relief hole 141 needs to turn inside the buffer chamber 14 before entering the air inlet 121. This can reduce the air flow speed and thus reduce the air volume entering the air inlet 121, further reducing the possibility of self-starting of the electronic atomization device 100.

[0053] In some examples, such as Figures 1 to 6 As shown, the shell assembly 10 includes an outer shell 15 and a sealing block 16. A buffer groove 151 is provided inside the outer shell 15, and a pressure relief hole 141 is recessed on the bottom wall of the buffer groove 151. The sealing block 16 is connected to the outer shell 15 and covers the notch of the buffer groove 151 to enclose a buffer cavity 14. The sealing block 16 is provided with an air inlet 121.

[0054] The sealing block 16 can be connected to the housing 15 in a variety of ways, such as bonding, plugging, etc. Specifically, in some examples, the sealing block 16 is provided with a recessed receiving groove along the contour of the notch of the buffer groove 151, and the peripheral wall of the buffer groove 151 plugs into and fits with the receiving groove to form abutment seal. In other examples, the sealing block 16 is in abutment with the notch of the buffer groove 151, and the sealing block 16 is provided with a protruding sealing ring along the contour of the notch of the buffer groove 151.

[0055] This arrangement aims to facilitate the installation of components of the housing assembly 10 by optimizing the specific structure of the housing assembly 10 , thereby improving the assembly efficiency of the housing assembly 10 .

[0056] In some examples, such as Figures 2 to 5 As shown, the pressure relief air duct 13 includes an air inlet section 131, which is connected to the first end of the starting air duct; a pressure relief groove is recessed on the side of the sealing block 16 facing away from the buffer chamber 14, and one side of the pressure relief groove is connected to the first end of the starting air duct, and the shell assembly 10 also includes a mounting plate 17, which is connected to the sealing block 16 and covers the notch of the pressure relief groove to enclose and form the air inlet section 131.

[0057] This configuration is intended to further optimize the specific structure of the housing assembly 10 to facilitate the installation of components of the housing assembly 10 and improve the assembly efficiency of the housing assembly 10. The sealing member can be manufactured by an integral molding process.

[0058] In some examples, such as Figures 4 to 9 As shown, the shell assembly 10 is also provided with an air collecting duct 18, one end of the air collecting duct 18 is connected to the air flow channel 11, and the other end of the air collecting duct 18 is respectively connected to the starting air channel and the pressure relief air channel 13, so that the starting air channel and the pressure relief air channel 13 are both connected to the air flow channel 11 through the air collecting duct 18.

[0059] Such a setting is intended to connect the starting air duct and the pressure relief air duct 13 with the air flow channel 11 through the air collecting duct 18, so as to reduce the total length of the starting air duct and the pressure relief air duct 13, reduce the air duct's occupancy of the internal space of the shell assembly 10, optimize the internal layout of the shell assembly 10, improve the integration, and facilitate the miniaturization of the electronic atomization device 100.

[0060] Similarly, the air collecting duct 18 also refers to an air duct for air flow, and does not specifically refer to the internal structure of a certain component. It can be formed by multiple components.

[0061] Of course, in other examples, the starting air passage and the pressure relief air passage 13 may be communicated with the air flow channel 11 respectively.

[0062] In some examples, such as Figures 2 to 5 As shown, the starting air passage includes a mounting section 122, which is located between the first end and the second end of the starting air passage. Mounting section 122 is used to mount the microphone 30. A first through hole 171 is provided through the mounting plate 17 along its thickness, and the first through hole 171 is in communication with the first end of the starting air passage. The housing assembly 10 also includes a cover 19, which is connected to the mounting plate 17 and covers the first through hole 171. The internal space enclosed by the cover 19 and the mounting plate 17, and the first through hole 171, together form the mounting section 122.

[0063] Such a configuration is intended to provide an internal space enclosed by the cover body 19 and the mounting plate 17 for the installation of the microphone 30, thereby improving the stability of the microphone 30 installed in the starting airway, and the microphone 30 can be arranged opposite to the first through hole 171 to improve the sensitivity of the microphone 30.

[0064] In some examples, such as Figures 2 to 5 As shown, the pressure relief air duct 13 also includes an air outlet section 132, one end of the air outlet section 132 is connected to the air collecting duct 18, and the other end of the air outlet section 132 is connected to the air inlet section 131; the mounting plate 17 is provided with a second through hole 172 along its thickness direction, and is connected to the air inlet section 131, and the cover body 19 is provided with a third through hole 191 along the thickness direction of the mounting plate 17, and is respectively connected to the second through hole 172 and the air collecting duct 18, and the second through hole 172 and the third through hole 191 together form the air outlet section 132.

[0065] In this example, the second through hole 172 and the third through hole 191 are coaxially arranged, and the air collecting duct 18 is located in the extension direction of the third through hole 191, which can further reduce the resistance of the air flow in the pressure relief air duct 13. Through the above arrangement, not only can the mounting plate 17 and the cover body 19 be used to form the mounting section 122 of the starting air duct, but the mounting plate and the cover body 19 can also be used to form the air outlet section 132, thereby making full use of the mounting part and the cover body 19, and further improving the integration of the shell assembly 10.

[0066] In some examples, such as Figures 2 to 9 As shown, an opening 192 is provided along the thickness direction of the mounting plate on the side of the cover 19 facing away from the mounting plate 17. This opening 192 is covered by a cover plate, a bracket 193, or a sticker, forming a slot with the cover 19. The slot opens toward the mounting portion and is used to accommodate the microphone 30. This arrangement further facilitates the installation of the microphone 30. In conjunction with the above description of the air collecting duct 18, in some examples, the air collecting duct 18 is provided on the bracket 193.

[0067] In some examples, such as Figure 1 As shown, the airflow inlet 111 of the airflow channel 11 is movably provided with a switch 40 for movably opening or closing the airflow channel 11. With this arrangement, the airflow channel 11 can be closed by the switch 40 when the electronic atomization device 100 is not in use, preventing external airflow from disturbing the gas within the airflow channel 11. At the same time, the switch 40 can prevent foreign matter from entering the airflow channel 11 through the airflow inlet 111.

[0068] In some examples, such as Figure 1 and Figure 4 As shown, the airflow outlet 112 of the airflow channel 11 is detachably mounted with a sealing plug 50. With this arrangement, the airflow outlet 112 can be sealed by the sealing plug 50 when the electronic atomization device 100 is not in use, preventing external airflow from disturbing the gas in the airflow channel 11. At the same time, the sealing plug 50 can prevent foreign matter from entering the airflow channel 11 through the airflow inlet 111.

[0069] In some examples, the electronic atomization device 100 further includes a sticker, which is used to be attached to the outer surface of the housing assembly 10 to respectively block the airflow inlet 111, the pressure relief hole 141, etc. mentioned above.

[0070] The above description is merely an optional embodiment of the present application and does not limit the patent scope of the present application. All equivalent structural transformations made using the contents of the present application specification and drawings under the inventive concept of the present application, or direct / indirect application in other related technical fields are included in the patent protection scope of the present application.
