Abstract
Description
Technical Field
[0001] This application relates to the field of atomization technology, and in particular to an electronic atomizer. Background Technology
[0002] Some e-cigarettes have a microphone inside. The air intake of the e-cigarette is connected to one side of the microphone, and the mouthpiece is connected to the other side of the microphone. When the user inhales, a negative pressure is created inside the e-cigarette. The capacitor structure in the microphone deforms due to the pressure difference, generating an electrical signal indicating a change in capacitance, thus triggering the microphone. After the microphone is triggered, the electronic control unit starts the atomization device.
[0003] However, during the transportation or use of e-cigarettes, there is a possibility that the air intake may be accidentally blocked. When the air intake is blocked, a pressure difference will form inside the microphone, causing it to be unintentionally triggered, thus unintentionally activating the atomizer. The atomized vapor remains inside the e-cigarette, causing increased internal pressure, which can easily lead to e-liquid leakage and safety hazards. Utility Model Content
[0004] The main objective of this application is to provide an electronic atomizer that solves the technical problem of the airflow sensing component being triggered due to accidental closure of the air intake.
[0005] To achieve the above objectives, this application proposes an electronic atomizer, the electronic atomizer comprising:
[0006] The outer casing has a first air inlet, and a pressure relief groove is formed on the outer wall of the outer casing. One end of the pressure relief groove is connected to the first air inlet, and a mist outlet is formed at one end of the outer casing.
[0007] A mounting base, disposed within the housing and communicating with the first air inlet and the mist outlet; and
[0008] An airflow sensing component is disposed within the mounting base and is sealed to the mounting base. The airflow sensing component includes a first sensing end and a second sensing end. The first sensing end is connected to the first air inlet, and the second sensing end is connected to the mist outlet.
[0009] Optionally, the pressure relief groove is formed by an inwardly recessed outer wall of the housing, and one end of the pressure relief groove away from the first air inlet extends out of the housing.
[0010] Optionally, the width of the pressure relief groove is greater than or equal to 0.3 mm and less than or equal to 1 mm.
[0011] Optionally, the length of the pressure relief groove is greater than or equal to 3 mm and less than or equal to 8 mm.
[0012] Optionally, the inner wall of the outer casing extends inward to form a connecting cylinder, and the mounting seat is disposed inside the connecting cylinder, and the mounting seat is sealed to the connecting cylinder.
[0013] Optionally, the first sensing end and the inner wall of the mounting base together form a ventilation cavity, and the electronic atomizer includes:
[0014] A ventilator is disposed inside the outer casing, and the two ends of the ventilator are respectively connected to the first air inlet and the venting chamber.
[0015] Optionally, the mounting base is connected to the inner wall of the housing on the side near the first air inlet, and the vent is sealed and inserted into the mounting base.
[0016] Optionally, the plane where the first sensing end is located intersects the plane where the first air inlet is located, and the angle between the intersections is 80° to 100°.

One end of the wire is electrically connected to the electronic control device, and the other end of the wire passes through the mounting base and is electrically connected to the first sensing end.
[0021] In the electronic atomizer of this application, when the first air inlet is accidentally closed, the gas between the first sensing end and the first air inlet can still be connected to the outside atmosphere through the pressure relief groove, so that the air pressure at the first sensing end remains unchanged, and thus the airflow sensing component will not be triggered unintentionally.

[0031] This application discloses an electronic atomizer, which includes a housing, a mounting base, and an airflow sensing component. The housing has a first air inlet, and a pressure relief groove is formed on the outer wall of the housing. One end of the pressure relief groove is connected to the first air inlet, and one end of the housing has a mist outlet. The mounting base is disposed inside the housing and is connected to the first air inlet and the mist outlet. The airflow sensing component is disposed inside the mounting base and is sealed to the mounting base. The airflow sensing component includes a first sensing end and a second sensing end. The first sensing end is connected to the first air inlet, and the second sensing end is connected to the mist outlet.
[0032] In the electronic atomizer of this application, when the first air inlet is accidentally closed, the gas between the first sensing end and the first air inlet can still be connected to the outside atmosphere through the pressure relief groove, so that the air pressure at the first sensing end remains unchanged, and thus the airflow sensing component will not be triggered unintentionally.
[0033] The following will mainly describe the specific structure of the electronic atomizer.
[0034] Please see Figure 1 and Figure 2 The electronic atomizer 100 of this application includes a housing 110. A first air inlet 111 is provided at the bottom end of the housing 110, and a pressure relief groove 112 is formed on the outer wall of the housing 110. One end of the pressure relief groove 112 is connected to the first air inlet 111, and the first air inlet 111 and the pressure relief groove 112 are in communication with the outside atmosphere.
[0035] Please see Figure 1 and Figure 2 The pressure relief groove 112 is formed by an inward indentation of the outer wall of the outer shell 110, which makes the electronic atomizer 100 more aesthetically pleasing and facilitates the fabrication of the pressure relief groove 112. The end of the pressure relief groove 112 furthest from the first air inlet 111 extends out of the outer shell 110. Therefore, even when the entire bottom surface of the outer shell 110 is undesirably sealed, the pressure relief groove 112 extending to the periphery of the outer shell 110 remains in communication with the outside atmosphere.
[0036] The width of the pressure relief groove 112 can be greater than, equal to, or less than the diameter of the first air inlet 111. The width of the pressure relief groove 112 can be greater than or equal to 0.3 mm and less than or equal to 1 mm. Therefore, the pressure relief groove 112 has a good pressure relief effect. Specifically, when the width of the pressure relief groove 112 is less than 0.3 mm, the pressure relief groove 112 is easily and undesirably sealed; when the width of the pressure relief groove 112 is greater than 1 mm, the electronic atomizer 100 is not aesthetically pleasing. Further, the width of the pressure relief groove 112 can be 0.3–0.5 mm, 0.35–0.45 mm, 0.4–0.75 mm, 0.45–0.55 mm, 0.5–0.7 mm, or 0.35–0.55 mm, etc. Furthermore, the width of the pressure relief groove 112 can be approximately 0.3mm, 0.35mm, 0.38mm, 0.39mm, 0.4mm, 0.41mm, 0.42mm, 0.45mm, 0.5mm, 0.55mm, 0.6mm, 0.65mm, 0.7mm, 0.75mm, 0.8mm, 0.85mm, 0.9mm, or 1mm, etc.
[0037] The pressure relief groove 112 can be a straight groove or a curved groove, without specific limitations. The length of the pressure relief groove 112 can be greater than or equal to 3mm and less than or equal to 8mm. Therefore, the pressure relief groove 112 has a good pressure relief effect. Specifically, when the length of the pressure relief groove 112 is less than 3mm, the pressure relief groove 112 is easily and undesirably completely closed; when the length of the pressure relief groove 112 is greater than 8mm, the electronic atomizer 100 is not aesthetically pleasing. Further, the length of the pressure relief groove 112 can be 3–5mm, 3.5–4.5mm, 4–7.5mm, 4.5–5.5mm, 5–7mm, or 4.5–6.5mm, etc. Even further, the length of the pressure relief groove 112 can be approximately 3mm, 3.5mm, 4mm, 4.1mm, 4.2mm, 4.3mm, 4.4mm, 4.5mm, 5mm, 5.5mm, 6mm, 6.5mm, 7mm, 7.5mm, or 8mm, etc.
[0038] Please see Figure 1 and Figure 2The outer casing 110 has a mist outlet 116 at one end for user inhalation. The electronic atomizer 100 includes an atomizing device 140 housed within the outer casing 110. The outer casing 110 has a second air inlet 115, and the second air inlet 115, the atomizing device 140, and the mist outlet 116 are sequentially connected. When the user inhales, outside air flows into the atomizing device 140 through the second air inlet 115, and the mist generated by the atomizing device 140 flows out through the mist outlet 116 under the guidance of the outside airflow and is inhaled by the user. The electronic atomizer 100 includes an electronic control device 150 housed within the outer casing 110. The electronic control device 150 supplies power to the atomizing device 140 and controls its operation.
[0039] Please see Figure 2 The electronic atomizer 100 of this application includes a mounting base 120, which is disposed inside the housing 110 and connects to a first air inlet 111 and a mist outlet 116. An atomizing device 140 and an electronic control device 150 are disposed outside the mounting base 120. The mounting base 120 also connects to a second air inlet 115.
[0040] Please see Figure 2 The electronic atomizer 100 of this application includes an airflow sensing component 130, which is disposed within and sealed to a mounting base 120. The airflow sensing component 130 and the mounting base 120 may be an interference fit. Alternatively, they may be snap-fitted or bonded. The mounting base 120 may be made of an elastic material (e.g., silicone, plastic, or rubber). The airflow sensing component 130 includes a first sensing end 131 and a second sensing end 132. The first sensing end 131 has a first air hole connected to a first air inlet 111. The second sensing end 132 has a second air hole connected to a mist outlet 116. The airflow sensing component 130 is electrically connected to an electronic control device 150. When a user inhales, a negative pressure is created inside the outer shell 110, creating a pressure difference inside the airflow sensing component 130, thereby triggering the airflow sensing component 130. The triggered airflow sensing component 130 further triggers the atomizing device 140 to operate via the electronic control device 150.
[0041] Please see Figure 2 The first sensor end 131 is connected to the second air inlet 115. Thus, when the user performs an inhalation action, the airflow sensing component 130 is triggered, the atomizing device 140 starts up quickly, and the user has a good user experience.
[0042] Please see Figure 2The inner wall of the outer casing 110 extends inward to form a connecting cylinder 114, and the mounting base 120 is disposed inside the connecting cylinder 114, with the mounting base 120 and the connecting cylinder 114 in a sealed connection. The mounting base 120 and the connecting cylinder 114 can be interference-fitted, snap-fitted, or adhesively bonded. Therefore, the mounting base 120 has a better installation effect inside the outer casing 110, and there is no gas leakage, which can ensure that the gas flow sensing component 130 is effectively triggered.
[0043] Please see Figure 2 The first sensing end 131 and the inner wall of the mounting base 120 together form a ventilation cavity 121. The electronic atomizer 100 includes a ventilation cylinder 113. The ventilation cylinder 113 is located inside the outer shell 110, and its two ends are respectively connected to the first air inlet 111 and the ventilation cavity 121. Through the guidance and limiting effect of the ventilation cylinder 113, the flow of outside air into the ventilation cavity 121 is relatively good.
[0044] Please see Figure 2 The mounting base 120 is connected to the inner wall of the housing 110 on the side near the first air inlet 111, and the vent 113 is sealed and inserted into the mounting base 120. Thus, on the one hand, the communication between the vent 113 and the vent chamber 121 is better, gas leakage is less likely, and the airflow sensing component 130 is triggered more effectively; on the other hand, it can further enhance the connection between the mounting base 120 and the housing 110.
[0045] Please see Figure 2 The plane containing the first sensing end 131 intersects the plane containing the first air inlet 111 at an angle of 80° to 100°. In other words, the first air inlet of the first sensing end 131 is not directly aligned with the first air inlet 111. Outside air is buffered within the ventilation chamber 121 before flowing into the first air inlet, resulting in relatively stable air pressure at the first sensing end 131 and thus ensuring good sensitivity of the airflow sensing component 130. Furthermore, this arrangement facilitates the installation of the airflow sensing component 130. For details, please refer to... Figure 2 The gas flow sensing component 130 includes a wire 134 and a sensor 133. The sensor 133 is disposed within and sealed to the mounting base 120. The sensor 133 includes the aforementioned first sensing end 131 and second sensing end 132. One end of the wire 134 is electrically connected to the electronic control device 150, and the other end of the wire 134 passes through the mounting base 120 and is electrically connected to the first sensing end 131. This arrangement facilitates the connection of the wire 134 to the first sensing end 131 while minimizing gas leakage. The sensor 133 can be a microphone. The sensor 133 is sealed to the mounting base 120 on its periphery, thus preventing gas leakage and resulting in high sensitivity.
