Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic atomization, in particular to a double-microphone control device and an aerosol generating device with the same. BACKGROUND

[0002] The aerosol generating device can heat an aerosol base material and atomize to generate an aerosol. The current aerosol generating device is mainly composed of an atomizer and a power supply for the atomizer. The atomizer generally includes a liquid storage compartment for storing a liquid base material, an air passage pipe arranged in the liquid storage compartment and configured to guide air outward, and an atomizing core arranged in the air passage pipe and in communication with the liquid storage compartment to heat and atomize the liquid base material.

[0003] When the aerosol generating device is in operation, the airflow generated by puffing is generally sensed by a microphone in the main machine. The airflow passing through the microphone causes vibration to turn on the circuit, and the control board is fed back with a signal to control the atomizer to heat and atomize. However, the main machine in the prior art generally only uses a single microphone for control. However, the microphone and the air inlet hole are generally arranged at the bottom of the main machine. When the condensed liquid at the upper part of the aerosol generating device drips down into the main machine along the air inlet channel, the condensed liquid is easy to adhere to the control board and the microphone, causing product damage. The condensed liquid entering the microphone can easily cause the circuit on the microphone to be turned on, resulting in a forced self-starting problem, which makes it impossible to effectively control the atomization work. In addition, the condensed liquid can overflow outward through the air inlet hole, causing a liquid leakage problem and affecting user experience. Furthermore, even if the microphone is arranged at a position where the condensed liquid is less likely to penetrate, the microphone can still be damaged due to various other reasons after long-term use, resulting in a relatively short service life of the aerosol generating device.

[0004] Secondly, the charging interface of the existing aerosol generating device is designed in an open type, which is easy to be damaged by dust and water.

[0005] In addition, the air inlet hole designed at the bottom of the main machine has only one or multiple air adjustment functions, resulting in an unadjustable suction resistance of the aerosol generating device during operation. SUMMARY

[0048] Example 1

[0049] like Figures 1-7 As shown in the figure, an aerosol generating device in this embodiment includes a housing 1, a battery 9, a dual-microphone control device, and a heating atomizing device. The dual-microphone control device is used to control whether the heating atomizing device is working or not. The heating atomizing device is used to store and heat the liquid matrix to form an aerosol for the user to inhale. The battery 9 is located inside the housing 1 and is used to power the dual-microphone control device and the heating atomizing device. The dual-microphone control device includes a first microphone assembly and a second microphone assembly.

[0050] The first microphone assembly includes a first circuit board 2 arranged at the top of the inner side of the shell 1 and a first microphone 3 arranged on the first circuit board 2, and the first circuit board 2 is electrically connected with the first microphone 3, the battery 9 and the heating atomization device respectively. At least one first air inlet hole 4 is arranged at the top of the shell 1 and is in communication with the first microphone 3, so that the flow of the airflow flowing from the first air inlet hole is detected by the first microphone. When the aerosol generating device is in operation, negative pressure is generated in the shell 1, and airflow flows into the first air inlet hole 4 at this time. The first microphone 3 detects the airflow and feeds back a signal to the first circuit board 2, and the first circuit board 2 controls the heating atomization device to work, atomizes the stored liquid substrate into aerosol for the user to smoke. It can be understood that the first air inlet hole in the embodiment has three and is arranged in sequence from left to right.

[0051] In the above, the first microphone and the first air inlet hole are arranged at the top of the shell, which can prevent the first microphone from being liquid-infiltrated and solve the damage problem caused by liquid leakage during use and transportation.

[0052] As a preferred, the top surface of the shell 1 is also slidably provided with a first sliding cover 5, and the first sliding cover 5 is slid relative to the shell 1 to close all or open at least one first air inlet hole 4. That is, the first sliding cover can close all the first air inlet holes 4 after sliding to limit the use of the aerosol generating device, which plays a role of child lock. Also, only one first air inlet hole, two first air inlet holes or all the first air inlet holes 4 can be opened in the sliding process, so as to control the number of opened first air inlet holes by sliding the first sliding cover 5, thereby realizing the adjustment of air and suction resistance.

[0053] As a preferred, the top end of the shell 1 is provided with two parallel and long strip-shaped sliding grooves 11, and the first sliding cover 5 is provided with buckles 51 engaged with the sliding grooves 11, so that the first sliding cover 5 slides forward and backward within the range of the sliding grooves 11, thereby limiting the sliding stroke of the first sliding cover 5.

[0054] As a preferred, a sealing ring 52 is sleeved on the inner side of the first sliding cover 5 close to the shell 1, which seals the first air inlet hole 4 and improves the sliding friction of the first sliding cover 5. That is, the first sliding cover 5 and the shell 1 have a certain tight fitting force, so that the hand feeling is good during sliding operation.

[0055] In the embodiment, the control device further comprises a charging interface 6 electrically connected with the first circuit board 2 and arranged on the top of the shell 1, which is used to connect with an external power supply to charge the battery 9 in the shell 1. The charging interface 6 and the first air inlet hole 4 are arranged at two ends of the sliding stroke of the first sliding cover 5, that is, the first sliding cover 5 can cover the first air inlet hole 4 or the charging interface 6 when sliding back and forth, that is, after the first sliding cover 5 slides relative to the shell 1, the first sliding cover 5 can close the charging interface 6 and open all the first air inlet holes 4, or the first sliding cover 5 can open the charging interface 6 and close all the first air inlet holes 4. In this structure, when the first sliding cover 5 slides to the top of the charging interface 6 and closes the charging interface 6, the first air inlet holes 4 at the other end are all opened. The closing effect of the first sliding cover 5 can avoid product damage caused by dust and water entering the charging interface 6. When the first sliding cover 5 slides to the top of the first air inlet hole 4 and closes all the first air inlet holes 4, the charging interface 6 at the other end is just opened. Therefore, when the first sliding cover 5 is opened for charging, the first air inlet holes 4 are closed to avoid using the aerosol generating device during charging. Thus, the first sliding cover functions as a charging cover and also has an air adjusting function, which is more compact and functional.

[0056] As preferred, the inner top of the shell 1 is provided with a fixed table 12 extending downward, and the first circuit board 2 is tightly fitted and fixed on the fixed table 12 by the fixing member 7, and the fixing member 7 covers the outer periphery of the charging interface 6, and the fixing member 7 is provided with a gas flow channel 71 communicating the first microphone 3 and at least one first air inlet hole 4, that is, the gas flow channel 71 can only communicate with one first air inlet hole to avoid that the size of the first microphone 3 limits the air inlet size of the plurality of first air inlet holes, so that the first air inlet hole can also be used as a pressure relief hole, and the other first air inlet holes 4 not communicating with the gas flow channel 71 are simply used for air inlet. The opening and closing of the first air inlet hole and the pressure relief hole are controlled by the first sliding cover 5. One end of the first air inlet hole 4 communicates with the first microphone 3, and the other end of the pressure relief hole communicates with the first microphone. When not in use, the device can be conveniently sealed to achieve dustproof and waterproof effects. When in use, the corresponding air holes required can be conveniently opened, and the waterproof design of the charging interface can better achieve the waterproof and dustproof effects.

[0059] In the embodiment, the second microphone assembly further includes a power switch 103 provided on the shell 1, which is electrically connected with the first circuit board 2 and the second microphone 100 respectively, for controlling the power supply of the second microphone 100, and when the second microphone 100 is short-circuited or forcibly turned on due to the infiltration of condensate, the connection circuit between the second microphone and the first circuit board is disconnected by using the power switch, which can effectively prevent the problem of false start.

When the second sliding cover 102 slides to the position of closing the second air inlet hole 101, the toggle handle 104 synchronously slides to the position of disconnecting the power supply, so that the power supply can be cut off while the second air inlet hole is closed, and the operation is simple and reliable. When the second sliding cover 102 reversely slides to the position of opening the second air inlet hole 101, the toggle handle reversely synchronously slides to the position of connecting the power supply.
