Description

Technical Field

[0001] This utility model relates to the field of electronic atomization equipment technology, and in particular to an electronic atomizer. Background Technology

[0002] Electronic atomizers are commonly used as cigarette alternatives or medical nebulization devices. Taking e-cigarettes as an example, a common electronic atomizer works by introducing e-liquid (the atomizing matrix) into a heating element, which then heats it to produce vapor. Some existing e-cigarettes use a microphone, which acts as an airflow sensor to detect changes in airflow and determine whether power is needed to power the heating element. When the user inhales, the microphone responds to changes in air pressure inside the e-cigarette and triggers the control circuit, causing the heating element to activate and atomize the e-liquid.

[0003] In the existing design, the microphone is located in the airflow channel inside the e-cigarette, and the airflow channel is connected to the oil storage chamber that stores e-liquid. This causes the e-liquid to flow to the microphone, which in turn affects the microphone's air pressure sensing accuracy. Utility Model Content

[0004] The main purpose of this invention is to propose an electronic atomizer that can solve the problem of microphones being easily contaminated and reducing sensing accuracy in the prior art.

[0005] To achieve the above objectives, this application provides an electronic atomizer, comprising:

[0006] The outer casing has an air inlet and an air outlet that connect to the outside atmosphere;

[0007] A bracket is disposed inside the outer shell. A first side of the bracket is provided with an atomizing chamber, one side of which is connected to the air outlet. The second side of the bracket is provided with an independent battery compartment and a microphone compartment. The microphone compartment and the battery compartment are respectively connected to the air inlet. One side of the battery compartment is connected to the atomizing chamber.

[0008] An air tube is disposed inside the outer shell. One end of the air tube near the first side is connected to the atomizing chamber, and the other end of the air tube is connected to the microphone chamber. The air inlet end of the air tube is not coaxial with the air inlet end of the atomizing chamber.

[0009] In some embodiments, the support includes an atomizer frame, a battery frame, and a microphone frame. The atomizer frame and the side of the outer shell near the air outlet define the atomizer chamber, and the atomizer frame is provided with an air inlet. The battery frame and the side of the outer shell near the air inlet define the battery chamber, and the battery frame is provided with an air outlet. The microphone frame and the inner part of the outer shell define the microphone chamber.

[0010] In some embodiments, the atomizer holder and the battery holder are spaced apart, and the space between them forms an airflow communication between the atomizer compartment and the battery compartment. The end of the air tube away from the microphone compartment extends into the airflow communication and connects the airflow communication with the microphone compartment.

[0011] In some embodiments, one end of the trachea that connects to the airflow connection protrudes from the surface of the battery holder.

[0012] In some embodiments, the electronic atomizer further includes absorbent cotton filling the gap.

[0013] In some embodiments, the battery holder is provided with an air guide column, the air guide column is hollow, one end of the air guide column is connected to the air inlet, and the other end of the air guide column protrudes from the surface of the battery holder and is higher than the end face of the oil-absorbing cotton.

[0014] In some embodiments, the microphone holder has a proximal end communicating with the trachea and a distal end away from the proximal end, with a bent flow channel extending between the proximal end and the distal end.

[0015] In some embodiments, the microphone holder and the battery holder are integrally formed.

[0016] In some embodiments, the housing includes a first housing and a second housing that are detachably connected. The air outlet is located on the first housing, and the air inlet is located on the second housing. The atomizing frame is connected to the first housing and defines the atomizing chamber. The battery holder is connected to the second housing and defines the battery chamber. After the first housing is connected to the second housing, the atomizing chamber and the battery chamber are in gas communication.

[0017] Compared with the prior art, this invention has obvious advantages and beneficial effects: the activation airway of the microphone is not coaxial with the air intake of the atomizing chamber, so the e-liquid is not easy to contaminate the microphone, thereby ensuring the microphone's sensing sensitivity.

[0027] Electronic atomizers can be used in various fields, such as medical atomization, beauty atomization, and cigarette replacement.

[0028] like Figures 1 to 5 As shown, this application provides an electronic atomizer, including a housing 10, a support 20, and an air tube 30. The housing 10 has an air inlet 101 and an air outlet 102 communicating with the outside atmosphere. The support 20 is disposed inside the housing 10. An atomizing chamber 11 is disposed on a first side of the support 20. One side of the atomizing chamber 11 is connected to the air outlet. The second side of the support 20 is provided with an independent battery compartment 12 and a microphone compartment 13. The microphone compartment 13 and the battery compartment 12 are respectively connected to the air inlet. One side of the battery compartment 12 is connected to the atomizing chamber 11. The air tube 30 is disposed inside the housing 10. One end of the air tube 30 near the first side is connected to the atomizing chamber 11, and the other end of the air tube 30 is connected to the microphone compartment 13. The air inlet end of the air tube 30 is not coaxial with the air inlet end of the atomizing chamber 11.

[0029] See Figure 1 As shown, the electronic atomizer includes a microphone 40, which senses changes in airflow to determine whether the atomizer needs to be activated. The microphone 40 is housed within the microphone chamber 13, with one side near the air inlet 101 and the other side near the outlet 102 via an air tube 30. When the user inhales, outside air passes through the atomization chamber 11, causing a pressure change on the side of the microphone near the air tube 30. The microphone 40 detects this pressure change within the microphone chamber 13, and the electronic atomizer responds to this internal pressure change by triggering the control circuit.

[0030] In some embodiments, the bracket 20 abuts against the inner wall of the housing 10, dividing the interior of the housing 10 into multiple independent spaces. At least one space is configured as an atomizing chamber 11, which houses an atomizing component to heat the atomizing matrix and generate vapor for consumption by the user. At least one space is configured as a battery compartment 12, which houses a power source to provide the necessary energy for the atomization operation of the electronic atomizer. At least one space is configured as a microphone compartment 13, which houses a microphone 40. The atomizing chamber 11 has an air inlet and an air outlet. The air inlet is connected to an air inlet 101 via the battery compartment 12, and the air outlet is connected to the outside atmosphere via an air outlet 102. The microphone compartment 13 is connected to the air inlet of the atomizing chamber 11 via an air tube 30.

[0031] See Figure 1As shown, the support 20 includes an atomizer frame 21, a battery holder 22, and a microphone holder 23. The atomizer frame 21 and the outer casing 10 near the air outlet define the atomizing chamber 11, and the atomizer frame 21 has an air inlet. The battery holder 22 and the outer casing 10 near the air inlet 101 define the battery chamber 12, and the battery holder 22 has an air outlet. The microphone holder 23 and the inner part of the outer casing 10 define the microphone chamber 13. External air enters the battery chamber 12 through the air inlet 101, then passes through the air outlet, and then enters the atomizer chamber 11. It is understood that the atomizer frame 21, the battery holder 22, and the microphone holder 23 are separable from each other, or the atomizer frame 21, the battery holder 22, and the microphone holder 23 can be integrally formed.

[0032] See Figure 1 As shown, the atomizer holder 21 and the battery holder 22 are spaced apart, forming an airflow connection 100 between the atomizer chamber 11 and the battery chamber 12. External air enters the battery chamber 12 through the air inlet, passes through the battery chamber 12, and then enters the atomizer chamber 11 through the space. It is understood that the airflow connection 100 formed by the space creates a deceleration zone for the incoming external air, especially when the air outlet of the battery chamber 12 and the air inlet of the atomizer chamber 11 are not coaxial, thus extending the airflow path. The end of the air tube 30 furthest from the microphone chamber 13 is inserted into the airflow connection 100, and the microphone chamber 13 is connected to the air inlet of the atomizer chamber 11 through the air tube 30. When the user inhales the electronic atomizer, external air passes through the airflow connection 100, changing the air pressure in the airflow connection 100, which in turn changes the air pressure within the air tube 30 and is sensed by the microphone 40.

[0033] See Figure 2 As shown, the atomizer rack 21 is positioned above the battery rack 22. The top of the battery rack 22 is recessed to form an oil collection groove 220, in which liquid flowing in through the air inlet of the atomizer chamber 11 can be collected.

[0034] In some embodiments, one end of the trachet 30 that connects to the airflow connection 100 protrudes from the surface of the battery holder 22. See also Figure 3 As shown, the air inlet of the air tube 30 is higher than the bottom of the oil accumulation tank 220. Understandably, when e-liquid flows into the airflow connection 100 through the air inlet of the atomizing chamber 11, the e-liquid needs to accumulate continuously in the airflow connection 100 until the e-liquid level is higher than the air inlet of the air tube 30 before it can flow into the air tube 30 and thus contaminate the microphone 40.

[0035] In some embodiments, the electronic atomizer further includes absorbent cotton 60 filled in the gaps. The absorbent cotton 60 is a porous medium capable of absorbing liquid flowing into the airflow communication 100 from inside the electronic atomizer. Figure 2As shown, the oil-absorbing cotton 60 is installed inside the oil collection tank 220. It can be understood that the gap is the airflow connection 100 mentioned above.

[0036] In some embodiments, see Figure 3 As shown, the battery holder 22 is equipped with a mounting slot for accommodating the battery 50. Specifically, the battery holder 22 is installed inside the housing 10, and the battery holder 22 is connected to the inner wall of the housing 10 and defines at least one space for fixing the battery 50. An air guide column 221 is provided on the top of the battery holder 22, and the air guide column 221 has an air outlet. One end of the air guide column 221 is connected to the air inlet 101, and the other end of the air guide column 221 protrudes from the bottom of the oil collection groove 220 and is higher than the end face of the oil-absorbing cotton 60 and communicates with the air inlet of the atomizing chamber 11.

[0037] In some embodiments, see Figure 4 As shown, the microphone frame 23 has a proximal end 231 connected to the air tube 30 and a distal end 232 away from the proximal end 231. A bent flow channel extends between the proximal end 231 and the distal end 232. The proximal end 231 is used to receive and communicate with the air tube 30, and the distal end 232 communicates with the air inlet 101. The side of the microphone frame 23 near the distal end 232 is spaced apart from the outer casing 10 to form a closed or semi-closed space with stable air pressure. See also Figure 5 As shown, the distal end 232 of the microphone frame 23 is provided with an air passage 233, which communicates with an air inlet 101 provided on the housing 10. It is understood that there can be multiple air inlets 101, and at least one air inlet communicates with the air passage 233. In some embodiments, the flow channel is U-shaped or L-shaped and runs through the microphone frame 23. The microphone frame 23 is fixed inside the housing 10. The side of the flow channel away from the air tube 30 communicates with the air inlet 101. The microphone 40 is installed on the side of the flow channel near the air inlet 101 so that the microphone 40 can sense the air pressure change on both sides of the microphone 40.

[0038] In some embodiments, the microphone holder 23 and the battery holder 22 can be integrally formed.

[0039] In some embodiments, housing 10 includes a detachably connected first housing and a second housing. See also Figure 4 As shown, the first housing has an air outlet 102 on its first side and an opening on its second side. An atomizing frame 21 is installed at the opening and is connected to the first housing to form an atomizing chamber 11. The second housing has an air inlet 101 on its first side and an opening on its second side. A battery holder 22 is connected to the second housing to form a battery chamber 12. A microphone holder 23 can be installed on either the first or second housing. The activation airway of the microphone 40 is made independent through an air tube 30. After the first and second housings are connected, the atomizing chamber 11 and the battery chamber 12 are in gas communication.
