Description

Technical Field

[0001] This application relates to the field of electronic atomization technology, and in particular to an electronic atomization device. Background Technology

[0002] Electronic atomizers, as a tobacco alternative, heat an aerosol product to form an aerosol, which is then inhaled through a mouthpiece. Specifically, when the user inhales, the microphone inside the electronic atomizer senses changes in airflow and sends an activation signal to the controller, thereby heating the aerosol product with a heating coil.

[0003] However, the casing and packaging of e-cigarettes are susceptible to damage from compression or exposure to extreme temperature and pressure changes. This can cause the microphone to self-start. Current technologies typically involve directly attaching the microphone to the circuit board, with a small vent hole designed at the microphone mounting location on the circuit board. This allows air to be supplied to the back of the microphone during inhalation, preventing the diaphragm from being "held back" by negative pressure and failing to trigger stably, or from failing to return to its original position after inhalation, resulting in delayed shutdown. However, this method cannot guarantee a completely sealed e-cigarette, and the risk of microphone self-starting remains. Utility Model Content

[0005] To solve the above-mentioned technical problems, this application provides an electronic atomizing device, including: a housing, an air inlet pipe, a circuit board, a microphone, and a support assembly.

[0006] The housing is provided with an air inlet, and a ventilation cavity is formed inside the housing;

[0008] The circuit board is disposed inside the housing;

[0009] One side of the microphone is electrically connected to the circuit board;

[0010] The bracket assembly is provided with a pressure relief channel, a mounting groove, and an air outlet channel. The microphone is located in the mounting groove and abuts against the inner wall of the mounting groove. The bracket assembly and one side of the circuit board form a sealed air passage. The sealed air passage is connected to the pressure relief channel and the pressure relief channel is connected to the pressure relief hole. One end of the air outlet channel is connected to the ventilation cavity, and the other end extends to the side of the microphone away from the circuit board.

[0011] In one possible embodiment of this application, the bracket assembly includes a seal and a mounting bracket, the pressure relief channel and the air outlet channel are disposed on the mounting bracket, the mounting groove is disposed on the seal, the seal is disposed on the mounting bracket, and the side of the seal near the circuit board surrounds the circuit board to form a sealed air passage.

[0012] In one possible embodiment of this application, the seal has a first sealing ring on the side near the circuit board, and the first sealing ring abuts against the circuit board.

[0013] In one possible embodiment of this application, the mounting bracket is provided with a positioning groove, the seal is placed inside the positioning groove, and the first sealing ring is placed outside the positioning groove.

[0014] In one possible embodiment of this application, the inner wall of the mounting groove is provided with a second sealing ring, which abuts against the side of the microphone.

[0015] In one possible embodiment of this application, the electronic atomizing device further includes a sealing plug that can selectively seal the air inlet.

[0016] In one possible embodiment of this application, the pressure relief hole is located close to the air inlet, and one end of the sealing plug can be selectively placed inside the air inlet pipe through the air inlet, with the air inlet and the end of the sealing plug spaced apart.

[0017] In one possible embodiment of this application, the diameter of the end of the air intake pipe that communicates with the ventilation chamber is smaller than the diameter of the end of the air intake pipe that is closer to the air intake hole.

[0018] In one possible embodiment of this application, the mounting bracket and the air intake pipe are made as a single molded structure;

[0019] And / or, the seal is made of silicone.

[0020] In one possible embodiment of this application, the electronic atomizing device includes an atomizer and an atomizing support. The atomizer is disposed on the atomizing support and has an atomizing tube. The atomizing support is disposed inside the housing. The ventilation chamber is provided at one end of the atomizing support away from the atomizer, and the atomizing tube communicates with the ventilation chamber.

[0021] The electronic atomizing device of this application comprises a housing, an air inlet pipe, a circuit board, a microphone, and a support assembly. The housing has an air inlet hole, and a ventilation chamber is formed within the housing. The air inlet pipe is located within the housing, with one end connected to the air inlet hole and the other end connected to the ventilation chamber.

This design places one end of the microphone within a sealed airway, which is connected to the air intake pipe via a pressure relief channel and a pressure relief hole. The other end of the microphone is located within an air outlet channel, which is connected to the ventilation chamber. Since both the ventilation chamber and the air intake pipe are part of the main airway of the electronic atomizing device, when both ends of the main airway are sealed, the pressure at both ends of the microphone remains consistent under various non-vaporization conditions, such as when the casing or packaging of the electronic atomizing device is squeezed, or during transportation, environmental changes such as high or low temperatures or cabin negative pressure. This prevents the microphone from automatically starting and improves the reliability and safety of the electronic atomizing device under non-vaporization conditions. Attached Figure Description

The following description is provided to enable any person skilled in the art to make and use this application. Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that this application can be made without using these specific details. In other instances, well-known structures and processes are not described in detail to avoid obscuring the description of this application with unnecessary detail. Therefore, this application is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0032] Please see Figures 1 to 4In one embodiment, this application proposes an electronic atomizing device, comprising: a housing 10, an air inlet pipe 20, a circuit board 30, a microphone 40, and a support assembly 50.

[0033] The housing 10 is provided with an air inlet 11, and a ventilation cavity 81 is formed inside the housing 10;

[0034] The intake pipe 20 is located inside the housing 10. One end of the intake pipe 20 is connected to the intake hole 11, and the other end is connected to the ventilation chamber 81. The intake pipe 20 is provided with a pressure relief hole 21.

[0035] Circuit board 30 is disposed inside housing 10;

[0036] The microphone 40 is electrically connected to the circuit board 30 on one side;

[0037] The bracket assembly 50 is provided with a pressure relief channel 521, a mounting groove 511, and an air outlet channel 522. The microphone 40 is located in the mounting groove 511 and abuts against the inner wall of the mounting groove 511. The bracket assembly 50 and one side of the circuit board 30 form a sealed air passage 54. The sealed air passage 54 is connected to the pressure relief channel 521. The pressure relief channel 521 is connected to the pressure relief hole 21. One end of the air outlet channel 522 is connected to the ventilation chamber 81, and the other end extends to the side of the microphone 40 away from the circuit board 30.

[0038] The housing 10 can be made of plastic. A power supply can be installed inside the housing 10. The power supply is electrically connected to the circuit board 30. The heating element (not shown) and the microphone 40 of the electronic atomizing device are both electrically connected to the circuit board 30. When the electronic atomizing device is used, the two ends of the microphone 40 can sense the pressure difference of the airflow and send a start signal to the controller (not shown) of the circuit board 30, thereby heating the heating element and heating the aerosol product, such as e-liquid, that has penetrated into the heating element, so that it mixes with the air to form an aerosol, which is then inhaled by the user.

[0039] The main airway of the electronic atomizing device may include an air inlet pipe 20 and an air passage 81. The diameter of the pressure relief hole 21 is smaller than that of the air inlet pipe 20. One side of the microphone 40 is electrically connected to the circuit board 30 via pins. The side of the microphone 40 is tightly abutted against the inner wall of the mounting groove 511. The side of the bracket assembly 50 near the circuit board 30 may be provided with a recessed groove (not shown). By tightly abutting the outer edge of the recessed groove of the bracket assembly 50 against the surface of the circuit board 30, a sealed airway 54 is formed, making the formation structure of the sealed airway 54 simpler.

[0040] This arrangement ensures that one end face of the microphone 40 is located within the sealed air passage 54, which is connected to the air inlet pipe 20 via a pressure relief channel 521 and a pressure relief hole 21. The other end face of the microphone 40 is located within the air outlet channel 522, which is connected to the ventilation chamber 81. Since both the ventilation chamber 81 and the air inlet pipe 20 are part of the main air passage of the electronic atomizing device, when both ends of the main air passage are sealed, the pressure at both ends of the microphone 40 remains consistent under various non-suction conditions, such as when the housing 10, outer packaging, or environmental changes during transportation, cabin negative pressure, etc., are squeezed. This prevents the microphone 40 from automatically starting and improves the reliability and safety of the electronic atomizing device under non-suction conditions.

[0041] Please see Figure 2 and Figure 3 In one embodiment, the bracket assembly 50 includes a seal 51 and a mounting bracket 52. A pressure relief channel 521 and an air outlet channel 522 are provided on the mounting bracket 52. A mounting groove 511 is provided on the seal 51. The seal 51 is provided on the mounting bracket 52. The side of the seal 51 near the circuit board 30 surrounds the circuit board 30 to form a sealed air passage 54.

[0042] The sealing element 51 can be made of silicone, and the mounting bracket 52 can be made of plastic. The mounting bracket 52 and the air inlet pipe 20 are integrally molded, thereby simplifying the structure of the electronic atomizing device and facilitating assembly. Furthermore, the side of the sealing element 51 near the circuit board 30 can be provided with a recessed groove. By tightly abutting the side of the sealing element 51 with the groove against the circuit board 30, a sealed air passage 54 is formed, which makes organization more convenient and enhances the sealing performance of the sealed air passage 54.

[0043] Please see Figure 2 and Figure 3 In one embodiment, a first sealing ring 512 is provided on the side of the sealing member 51 near the circuit board 30, and the first sealing ring 512 abuts against the circuit board 30. The first sealing ring 512 may be integrally formed with the sealing member 51, and the cross-section of the first sealing ring 512 may be a conical structure or a semi-circular structure, so that it can tightly abut against the circuit board 30 through elastic deformation, further enhancing the sealing performance of the sealing air passage 54.

[0044] Please see Figures 2 to 4 In one embodiment, the mounting bracket 52 is provided with a positioning groove 523, the sealing member 51 is placed inside the positioning groove 523, and the first sealing ring 512 is placed outside the positioning groove 523. The positioning groove 523 facilitates the quick assembly of the sealing member 51, and the sealing member 51 can elastically abut against the inner wall of the positioning groove 523, thereby enhancing the stability of the connection.

[0045] Please see Figure 2 and Figure 3 In one embodiment, a second sealing ring 513 is provided on the inner wall of the mounting groove 511, and the second sealing ring 513 abuts against the side of the microphone 40. The second sealing ring 513 can be integrally formed with the sealing element 51, and the cross-section of the second sealing ring 513 can be a conical or semi-circular structure, thereby allowing it to tightly abut against the side of the microphone 40 through elastic deformation, thus improving the sensitivity of the microphone 40. Furthermore, multiple second sealing rings 513 can be used, further improving the sensitivity of the microphone 40 and making the installation of the microphone 40 more secure.

[0046] Please see Figure 1 and Figure 2 In one embodiment, the electronic atomizing device further includes a sealing plug 60, which can selectively seal the air inlet 11. The sealing plug 60 may be made of silicone. By sealing the air inlet 11 with the sealing plug 60, the electronic atomizing device can be kept out of use, such as during transportation or long-term storage, to prevent the e-liquid from escaping or leaking oil from the air inlet 11, thus improving the convenience of early use.

[0047] Please see Figure 1 In one embodiment, the pressure relief hole 21 is positioned close to the air inlet 11, and one end of the sealing plug 60 can selectively pass through the air inlet 11 and be placed inside the air intake pipe 20. The air inlet 11 and the end of the sealing plug 60 are spaced apart. This prevents the sealing plug 60 from sealing the pressure relief hole 21, and the proximity of the pressure relief hole 21 to the air inlet 11 increases the distance between the pressure relief hole 21 and the ventilation chamber 81, thereby improving the sensitivity of the microphone 40.

[0048] Please see Figure 1 In one embodiment, the diameter of the end of the air intake pipe 20 that connects to the ventilation chamber 81 is smaller than the diameter of the end of the air intake pipe 20 near the air intake hole 11. The port of the air intake pipe 20 may be a funnel-shaped structure, thereby increasing the flow rate of air from the air intake pipe 20 into the ventilation chamber 81, thus improving the sucking experience.

[0049] Please see Figure 1 In one embodiment, the electronic atomizing device includes an atomizer 70 and an atomizing support 80. The atomizer 70 is disposed on the atomizing support 80 and has an atomizing tube 71. The atomizing support 80 is disposed within the housing 10. An air vent 81 is provided at the end of the atomizer 70 away from the atomizer 70, and the atomizing tube 71 communicates with the air vent 81. The heating wire may be disposed within the atomizing tube 71, and the main air duct may include the atomizing tube 71. By placing the air vent 81 at the end of the atomizing support 80 away from the atomizer 70, the overall assembly structure of the electronic atomizing device is simplified, and assembly efficiency is improved.

[0050] In practice, each of the above units or structures can be implemented as an independent entity or can be arbitrarily combined to be implemented as the same or several entities. For the specific implementation of each of the above units or structures, please refer to the previous method embodiments, which will not be repeated here.

[0051] The electronic atomizing device provided in the embodiments of this application has been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of this application. The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this application.
