Description

Technical Field

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

[0002] In existing airflow triggering technologies for electronic atomization devices, microphones (MEMS sound pressure / air pressure sensors) offer significant advantages over mechanical airflow switches or purely manual buttons: microphones are contactless solid-state devices, eliminating issues like lever fatigue, oxidation, or jamming, and maintaining a startup delay of ≤10ms throughout their lifespan; their sensitivity, determined by both the MEMS diaphragm and ASIC algorithm, can detect pressure differences as low as 50Pa, reducing suction resistance and preventing false triggering; furthermore, the microphone's fully sealed packaging provides dust and condensation protection, significantly extending its lifespan and improving product consistency. In contrast, mechanical switches must overcome spring hysteresis and contact resistance, while manual buttons require additional structural space and increase user operation steps; both are inferior to microphone solutions in terms of size, reliability, and user experience.

[0003] However, in the "high-power" category (typically referring to open-type or replaceable-coil devices with power ≥30W and output current ≥10A), microphones are rarely used as the main airflow sensor. The main reason is that high-power e-cigarettes generally employ open airflow channels to achieve extremely low draw resistance (ΔP<20Pa). This pressure difference is close to the microphone's noise floor, easily leading to false triggering or startup failure. Therefore, high-power e-cigarettes still commonly use mechanical buttons or Hall effect buttons as the activation method, while microphones are mainly reserved for disposable, closed-type, or low-power e-cigarettes.

[0005] One embodiment of this application provides an atomizing host, comprising: a host housing having a connecting end for detachable connection with an atomizer; an air inlet and an air outlet are also provided on the host housing on the same side as the connecting end; a first air inlet channel is also provided inside the host housing, one end of the first air inlet channel is connected to the air inlet, and the other end is connected to the air outlet; the end of the air inlet opposite to the first air inlet channel is connected to the outside, and the end of the air outlet opposite to the first air inlet channel is used to connect to the mouthpiece of the atomizer; a power supply is disposed inside the host housing; a circuit board is disposed inside the host housing and electrically connected to the power supply; an airflow sensor is disposed inside the host housing and electrically connected to the circuit board; the airflow sensor is located inside the first air inlet channel; and a throttling component is movably disposed on the connecting end to simultaneously close the air inlet and the air outlet, and simultaneously open the air inlet and the air outlet.

[0006] In one embodiment, the connection end has a threaded connection port for detachable connection with an atomizer.

[0007] In one embodiment, the throttle assembly includes a rotating component and a switching component. The switching component is connected to the rotating component, and the rotating component is arranged around a threaded connection port. The switching component can drive the rotating component to rotate around the threaded connection port to simultaneously open the air inlet and the air outlet, and simultaneously close the air inlet or the air outlet.

[0008] In one embodiment, it further includes a first sealing element, with a mounting groove provided around the threaded connection port at the connecting end, at least partially disposed in the mounting groove, and an air outlet and an air inlet disposed on the bottom wall of the mounting groove; the first sealing element is at least partially located between the bottom wall of the mounting groove and the rotating element, for sealing the gap between the rotating element and the bottom wall of the mounting groove.

[0009] In one embodiment, the air inlet and air outlet are located on opposite sides of the threaded connection.

[0010] In one embodiment, the device further includes a bracket and a first electrical connection structure. The bracket is disposed inside the main housing and has a support protrusion at the position corresponding to the threaded connection port. The first electrical connection structure is connected to the support protrusion and extends into the threaded connection port to contact the second electrical connection structure of the atomizer.

[0011] In one embodiment, a first elastic element is further included. The first elastic element is sleeved on the support protrusion, and the end of the first elastic element facing away from the support protrusion is connected to the first electrical connection structure. The first elastic element has a restoring force that pushes the first electrical connection structure toward the threaded connection port.

[0012] In one embodiment, a second seal is further included, which is disposed at least on the periphery of the air outlet and the periphery of the threaded connection port to seal the connection between the atomizing host and the atomizer.

[0014] One embodiment of this application provides an electronic atomization device, including the aforementioned atomizing host and atomizer, wherein the connection end between the atomizer and the atomizing host is detachably connected, and the atomizing host is used to supply power to the atomizer.

[0015] This application provides an atomizing host and an electronic atomizing device. The atomizing host includes a host housing, a power supply, a circuit board, an airflow sensor, and a throttle assembly. An air inlet and an air outlet are provided on the host housing, located on the same side as the connection end. A first air intake channel within the host housing connects the air inlet and the air outlet. The airflow sensor is located within the first air intake channel, and the throttle assembly is movably mounted at the connection end. When vaping is required, adjusting the throttle assembly opens the air inlet and the air outlet. External airflow flows from the air inlet through the airflow sensor in the first air intake channel and exits from the air outlet. The airflow sensor detects the change in airflow and transmits a signal to the circuit board, reducing the possibility of startup failure. When the electronic atomizing device is not in use, adjusting the throttle assembly closes the air inlet and the air outlet, reducing the inflow of external air into the host housing and preventing the airflow sensor from being falsely triggered.

[0025] Example 1

[0026] This embodiment provides an atomizing host 100. Please refer to [reference needed]. Figure 1-5 The atomizing host 100 includes a host housing 110, a power supply 120, a circuit board 130, an airflow sensor 140, and a throttling component 150.

[0027] Please refer to Figure 1-2 and Figure 4 The main unit housing 110 has a connecting end 111 for detachable connection with the atomizer 300. On the same side of the main unit housing 110 as the connecting end 111, there is also an air inlet 112 and an air outlet 113. A first air intake channel 114 is also provided inside the main unit housing 110. One end of the first air intake channel 114 communicates with the air inlet 112, and the other end communicates with the air outlet 113. The end of the air inlet 112 opposite to the first air intake channel 114 is connected to the outside, and the end of the air outlet 113 opposite to the first air intake channel 114 is used to communicate with the mouthpiece 350 of the atomizer 300. A power supply 120 is located inside the main unit housing 110. A circuit board 130 is located inside the main unit housing 110 and is electrically connected to the power supply 120. The airflow sensor 140 is disposed inside the main unit housing 110 and electrically connected to the circuit board 130. The airflow sensor 140 is located inside the first air intake channel 114. The throttle assembly 150 is movably disposed at the connection end 111 to simultaneously close the air intake 112 and the air outlet 113, and simultaneously open the air intake 112 and the air outlet 113.

[0028] In this embodiment, the airflow sensor 140 is disposed inside the main unit housing 110, and an air inlet 112 and an air outlet 113 are provided at the connection end 111 of the main unit housing 110. A first air intake channel 114 is provided inside the main unit housing 110, with one end of the first air intake channel 114 connected to the air inlet 112 and the other end connected to the air outlet 113. The airflow sensor 140 is located on the first air intake channel 114, and the throttle component 150 is movably disposed at the connection end 111 so as to simultaneously close the air inlet 112 and the air outlet 113, thereby realizing the airflow sensor 140 sensing airflow triggering, and preventing external airflow from flowing in when the air inlet 112 and the air outlet 113 are closed, thus avoiding false triggering.

[0029] Additionally, it should be noted that high-power electronic cigarettes typically require support for high power output and large airflow. However, the airflow sensor 140 is susceptible to signal distortion due to turbulence in high-speed flow environments, significantly reducing its reliability. In this application, both the air inlet 112 and the air outlet 113 are relatively small. Achieving a large airflow mainly relies on the airflow of the atomizer 300. This design serves two purposes: firstly, the small airflow of the atomizing host 100 can prevent signal distortion caused by turbulence in the airflow sensor 140, improving reliability; secondly, the airflow of the atomizer 300 can meet the large airflow requirements of the electronic atomization device 400.

[0030] Please refer to Figure 1 The connecting end 111 has a threaded connection port 1111, which is used for detachable connection with the atomizer 300.

[0031] In this embodiment, the atomizing host 100 and the atomizer 300 are connected by a threaded connection port 1111, which can improve the stability of the connection between the two.

[0032] Please refer to Figure 1 and Figure 4 The throttle assembly 150 includes a rotating member 151 and a switching member 152. The switching member 152 is connected to the rotating member 151. The rotating member 151 is arranged around the threaded connection port 1111. The switching member 152 can drive the rotating member 151 to rotate around the threaded connection port 1111, so as to simultaneously open the air inlet 112 and the air outlet 113, and simultaneously close the air inlet 112 or the air outlet 113. More specifically, the rotating component 151 is provided with a first through hole 1511 and a second through hole 1512. When the switching component 152 drives the rotating component 151 to rotate, so that the first through hole 1511 is aligned with the air inlet 112 and the second through hole 1512 is aligned with the air outlet 113, the air inlet 112 and the air outlet 113 are in the open state. When the switching component 152 drives the rotating component 151 to rotate, so that the first through hole 1511 is misaligned with the air inlet 112 and the second through hole 1512 is misaligned with the air outlet 113, the air inlet 112 and the air outlet 113 are in the closed state.

[0033] By using the switch 152 to move the rotating part 151, the air inlet 112 and the air outlet 113 can be closed and opened. The structure is simple and the operation is convenient.

[0034] Please refer to Figure 1 and Figure 4The atomizing host 100 also includes a first sealing element 160. A mounting groove 1112 is provided around the threaded connection port 1111 at the connecting end 111. A rotating member 151 is at least partially disposed within the mounting groove 1112. An air outlet 113 and an air inlet 112 are disposed at the bottom of the mounting groove 1112. The first sealing element 160 is at least partially located between the bottom wall of the mounting groove 1112 and the rotating member 151, used to seal the gap between the rotating member 151 and the bottom wall of the mounting groove 1112. More specifically, in this embodiment, the connecting end 111 is an end face exposed outside the host housing 110, and the first sealing element 160 extends to the entire end face of the connecting end 111, which can be used for waterproofing, dustproofing, and drop protection.

[0035] In this application, the first seal 160 not only serves to prevent water, dust, and drops, but also seals the main unit casing 110 as much as possible. When the air inlet 112 and the air outlet 113 are open, the external airflow enters the first air intake channel 114 through the air inlet 112 and flows out through the air outlet 113. When the air inlet 112 and the air outlet 113 are closed, it is also difficult for the external airflow to enter the main unit casing 110 and circulate. The airflow sensor 140 of the first air intake channel 114 is less likely to be falsely triggered.

[0036] Please refer to Figure 2 The atomizing host 100 also includes a bracket 170 and a first electrical connection structure 180. The bracket 170 is disposed inside the host housing 110. The bracket 170 has a support protrusion 171 at the position corresponding to the threaded connection port 1111. The first electrical connection structure 180 is connected to the support protrusion 171 and extends into the threaded connection port 1111 to contact the second electrical connection structure 380 of the atomizer 300.

[0037] In this embodiment, the first electrical connection structure 180 is connected to the support protrusion 171 and extends into the threaded connection port 1111. When the atomizing host 100 is connected to the atomizer 300 through the threaded connection port 1111, the first electrical connection structure 180 can be electrically connected to the second electrical connection structure 380 in the atomizer 300, making assembly simple and convenient.

[0038] Please refer to Figure 2 and Figure 5 The atomizing host 100 also includes a first elastic element 190, which is sleeved on the support protrusion 171, and the end of the first elastic element 190 away from the support protrusion 171 is connected to the first electrical connection structure 180. The first elastic element 190 has a restoring force that pushes the first electrical connection structure 180 toward the threaded connection port 1111.

[0039] The first elastic element 190 can securely connect the first electrical connection structure 180 to the second electrical connection structure 380 of the atomizer 300.

[0040] Please refer to Figure 2 In this embodiment, a power supply mounting cavity 172 is defined within the bracket 170. The top of the power supply mounting cavity 172 is positioned facing the connection end 111, and the top of the power supply mounting cavity 172 has an opening 1721. Figure 2 The atomizing host 100 also includes a support plate 200, a third electrical connection structure 220, and a second elastic member 230. The support plate 200 is disposed in the space between the connection end 111 and the top of the cavity of the power supply mounting cavity 172. The side of the support plate 200 away from the connection end 111 has an abutment post 210. The third electrical connection structure 220 is disposed at the top opening 1721 of the cavity of the power supply mounting cavity 172. The second elastic member 230 is sleeved on the abutment post 210. The end of the second elastic member 230 away from the abutment post 210 abuts against the third electrical connection structure 220. The end of the third electrical connection structure 220 away from the abutment post 210 is in contact with the power supply 120. The abutment post 210 and the second elastic member 230 can fix the third electrical connection structure 220 to the opening 1721. The number of abutment posts 210 corresponds to the number of batteries, and the number of third electrical connection structures 220 also corresponds to the number of batteries. For example, when there are two batteries, there are two abutment posts 210 and two third electrical connection structures 220. It should be noted that in this application, the first electrical connection structure 180 is electrically connected to the positive terminal of the power supply 120, and the third electrical connection structure 220 is electrically connected to the negative terminal of the power supply 120, forming a complete circuit.

[0041] The atomizing host 100 also includes a second seal 240, which is provided at least on the periphery of the air outlet 113 and the periphery of the threaded connection port 1111 to seal and connect the atomizing host 100 and the atomizer 300.

[0042] Please refer to Figure 1-2In this embodiment, the atomizing host 100 further includes a fixing plate 250, which is disposed on the connecting end 111 and on the rotating member 151, for confining the rotating member 151 within the mounting groove 1112 to prevent the rotating member 151 from disengaging from the mounting groove 1112. The fixing plate 250 has a connecting opening 251 and a recessed groove 252 in its middle. The connecting opening 251 is used for detachable connection with the atomizer 300. The recessed groove 252 surrounds the connecting opening 251. A second sealing member 240 is disposed within the recessed groove 252 and partially extends out of the recessed groove 252 to seal the connection between the atomizing host 100 and the atomizer 300. Additionally, the first sealing member 160 has a third through hole 161 and a fourth through hole 162. One end of the third through hole 161 communicates with the air inlet 112, and the other end communicates with the first through hole 1511. The bottom of the recessed groove 252 is provided with a through hole 2521, which is aligned with the air outlet 113. The second seal 240 is provided with a fifth through hole 241, which is aligned with the through hole 2521.

[0043] The second seal 240 is used to seal the connection between the atomizing host 100 and the atomizer 300, prevent air leakage between the atomizing host 100 and the atomizer 300, and prevent air leakage from affecting the airflow in the atomizing host 100 from the air outlet 113 to the mouthpiece of the atomizer 300, thereby improving the sensitivity of the airflow sensor 140.

[0044] Please refer to Figure 1 The air inlet 112 and the air outlet 113 are located on opposite sides of the threaded connection 1111.

[0045] In this application, because a first seal 160 and a second seal 240 are required, the air inlet 112 and the air outlet 113 are positioned on opposite sides of the threaded connection 1111, meaning the distance between the air inlet 112 and the air outlet 113 is relatively large, which facilitates the arrangement of the second seal 240. If the air inlet 112 and the air outlet 113 were positioned on the same side of the threaded connection 1111, in addition to assembling the rotating component 151 and the switching component 152, the second seal 240 would also need to be installed at the positions of the air inlet 112 and the air outlet 113. This would result in an overly dense and crowded structural arrangement and poor structural stability.

[0046] Please refer to Figure 2 The power supply 120 includes at least two batteries connected in series, and the total volume of all batteries occupies at least half of the internal cavity of the main unit housing 110.

[0047] In this embodiment, the atomizing host 100 is mainly used in high-power electronic atomizing devices. The space inside the host housing 110 is mainly used to accommodate the battery, while the atomizing component 370 is located in the atomizer 300, which can reserve more space for the battery and thus achieve high-power power supply.

[0048] More specifically, the circuit board 130 is disposed inside the main unit housing 110 near the side wall of the inner cavity of the main unit housing 110.

[0049] Example 2

[0050] This embodiment provides an electronic atomizing device 400. Please refer to [reference needed]. Figure 3-5 It includes the atomizing host 100 and atomizer 300 in Embodiment 1. The connection end 111 of the atomizer 300 and the atomizing host 100 is detachably connected, and the atomizing host 100 is used to supply power to the atomizer 300.

[0051] Please refer to Figure 4-5 The atomizer 300 includes an atomizing chamber 310, an atomizer housing 320, a base 330, a mounting bracket 340, a mouthpiece 350, an airflow regulating ring 360, and an atomizing assembly 370. The base 330 is connected to the atomizer housing 320. The atomizing chamber 310 is disposed inside the atomizer housing 320 and supported on the base 330. The mounting bracket 340 is connected to the side of the atomizing chamber 310 away from the base 330. The side wall of the mounting bracket 340 has an air inlet 341. The airflow regulating ring 360 is rotatably sleeved around the periphery of the mounting bracket 340, and the airflow regulating ring 360 is provided with an airflow regulating port 361. By rotating the airflow regulating ring 360, the airflow regulating port 361 can be aligned with the air inlet 112. The aligned area can be determined by the user. Alternatively, the airflow regulating port 361 can be misaligned with the air inlet 112, thus allowing the user to determine the airflow volume of the atomizer 300. The atomizing chamber 310 and the mounting bracket 340 define a second air intake channel 311. The atomizing chamber 310 has an atomizing cavity 312, and the atomizing component 370 is disposed in the atomizing cavity 312. One end of the second air intake channel 311 communicates with the air intake port 341, and the other end communicates with the atomizing cavity 312. The mouthpiece 350 is connected to the end of the mounting bracket 340 opposite to the atomizing chamber 310, and the atomizing cavity 312 communicates with the mouthpiece 350.

[0052] In addition, such as Figure 5 An air inlet 331 is provided on the side of the base 330 that contacts the atomizing host 100. The air inlet 331 is connected to the fifth through hole 241 of the second seal 240.

[0053] In this embodiment, the air inlet 341 of the atomizer 300 supplies the majority of the air intake to the electronic atomizing device 400. The air inlet 112 and air outlet 113 of the atomizing host 100 contribute only a small amount of air intake. Furthermore, the air inlet 112 and air outlet 113 of the atomizing host 100 mainly contribute to the response of the airflow sensor 140, enabling the airflow sensor 140 to be triggered even in low airflow scenarios, thus avoiding signal distortion caused by turbulence in the airflow sensor 140.

[0054] The above-described specific examples are for illustrative purposes only and are not intended to limit the scope of this invention. Those skilled in the art to which this invention pertains can make various simple deductions, modifications, or substitutions based on the concept of this invention.
