Description

Technical Field

[0001] The utility model relates to the technical field of electronic atomization, in particular to a starting trigger device based on a magnetic pneumatic switch and an atomization device. Background Art

[0002] Atomizing devices, such as electronic cigarettes, generally have a built-in microphone switch. The microphone switch senses the airflow generated in the airflow channel when the user inhales to start the atomizing device, thereby prompting the atomizing device to heat the atomizing medium to generate an atomized aerosol for the user to inhale. The microphone switch is generally a capacitive switch. When the atomizing medium built into the atomizing device leaks or condenses, the microphone switch is easily corroded by the atomizing medium and affects the start-up of the atomizing device. Therefore, an electromagnetic switch is currently used, such as the Chinese invention patent application with application number 202110360217.3, which discloses a split electromagnetic induction switch device. That is, the electromagnetic microphone is used to start the atomization device. Specifically, it makes the smoke oil leak only along the airway to the elastic membrane and the magnet block, and will not corrode and damage components such as the magnetic field sensor. That is, the split electromagnetic induction switch device for electronic cigarettes is not affected by oil leakage, is not easy to be damaged, and has a long service life. However, the elastic membrane in the current electromagnetic switch is generally made of elastic metal material. Although it has a certain corrosion resistance, after long-term research and development and investigation, it is found that for the long-term use of the atomization device, when the microphone switch is immersed in the atomization medium for a long time, there is still a large number of atomization media infiltrating components and circuit boards, thereby affecting the startup of the atomization device.

[0030] The present application provides a start trigger device based on a magnetic pneumatic switch. The above-mentioned start trigger device based on a magnetic pneumatic switch includes an electronic cigarette PCB board, a shell and a magnetic pneumatic switch. The electronic cigarette PCB board is built into the shell, and the shell is provided with an air flow channel. The magnetic pneumatic switch includes a shell, a pneumatic membrane, a magnetic field generating part and a signal processing part. The shell is built into the shell, and at least one vent is provided on the shell, the vent is connected to the air flow channel, and the vent is located on one side of the pneumatic membrane and is connected to the pneumatic membrane. The outer periphery of the pneumatic membrane is connected to the inner wall of the shell, the magnetic field generating part is connected to the pneumatic membrane, the signal processing part is built into the shell and is located on the side of the pneumatic membrane away from the vent, and the signal processing part is arranged opposite to the magnetic field generating part, and the signal processing part is electrically connected to the electronic cigarette PCB board. Among them, the pneumatic membrane is a polyethylene pneumatic membrane, a polypropylene pneumatic membrane, a polyvinyl chloride pneumatic membrane, a polystyrene pneumatic membrane or a polycarbonate pneumatic membrane.

[0031] The above-mentioned starting trigger device based on the magnetic pneumatic switch makes the vent hole connected to the air flow channel, and the vent hole is located on one side of the pneumatic membrane and connected to the pneumatic membrane, so that the magnetic field generating component is connected to the pneumatic membrane, and the signal processing component is built into the shell and located on the side of the pneumatic membrane away from the vent hole. In this way, the pneumatic membrane realizes the isolation of the vent hole and the signal processing component. The pneumatic membrane is further matched with a polyethylene pneumatic membrane, a polypropylene pneumatic membrane, a polyvinyl chloride pneumatic membrane, a polystyrene pneumatic membrane or a polycarbonate pneumatic membrane, which better ensures the elastic agitation of the pneumatic membrane with the air flow and better improves the anti-corrosion strength of the pneumatic membrane under the infiltration of the atomized medium, thereby realizing that the starting trigger device based on the magnetic pneumatic switch has higher starting stability under long-term use.

[0032] In order to better understand the start trigger device based on the magnetic pneumatic switch of the present application, the start trigger device based on the magnetic pneumatic switch of the present application is further explained as follows:

[0033] Please also read Figures 1 to 4, A starting trigger device 10 based on a magnetic pneumatic switch in one embodiment includes an e-cigarette PCB board 100, a housing 200, and a magnetic pneumatic switch 300. The e-cigarette PCB board 100 is built into the housing 200, and the housing 200 is provided with an air flow channel 201. The magnetic pneumatic switch 300 includes a housing 310, a pneumatic membrane 320, a magnetic field generating member 330, and a signal processing member 340. The housing 310 is built into the housing 200, and at least one air vent 301 is provided on the housing 310. The air vent 301 is communicated with the air flow channel 201, and the air vent 301 is located on one side of the pneumatic membrane 320 and communicated with the pneumatic membrane 320. The outer periphery of the pneumatic membrane 320 is connected to the inner wall of the housing 310. The magnetic field generating member 330 is connected to the pneumatic membrane 320. The signal processing member 340 is built into the housing 310 and located on the side of the pneumatic membrane 320 away from the air vent 301. The signal processing member 340 is disposed opposite to the magnetic field generating member 330, and the signal processing member 340 is electrically connected to the e-cigarette PCB board 100. Among them, the pneumatic membrane is a polyethylene pneumatic membrane, a polypropylene pneumatic membrane, a polyvinyl chloride pneumatic membrane, a polystyrene pneumatic membrane, or a polycarbonate pneumatic membrane.

[0034] For the above-mentioned starting trigger device 10 based on a magnetic pneumatic switch, the air vent 301 is communicated with the air flow channel 201, and the air vent 301 is located on one side of the pneumatic membrane 320 and communicated with the pneumatic membrane 320. The magnetic field generating member 330 is connected to the pneumatic membrane 320, and the signal processing member 340 is built into the housing 310 and located on the side of the pneumatic membrane 320 away from the air vent 301. In this way, the pneumatic membrane 320 realizes the isolation between the air vent 301 and the signal processing member 340. Further, in cooperation with the pneumatic membrane being a polyethylene pneumatic membrane, a polypropylene pneumatic membrane, a polyvinyl chloride pneumatic membrane, a polystyrene pneumatic membrane, or a polycarbonate pneumatic membrane, it preferably ensures the elastic agitation of the pneumatic membrane 320 with the air flow and preferably improves the anti-corrosion strength of the pneumatic membrane 320 under the infiltration of the atomization medium. Furthermore, the starting trigger device 10 based on a magnetic pneumatic switch has high starting stability during long-term use.

[0035] In one embodiment, the thickness of the pneumatic membrane is 3μm to 8μm. Further, the thickness of the pneumatic membrane is 4μm, which preferably ensures that during the suction process, the air flow can drive the elastic agitation of the pneumatic membrane, and further realizes the elastic agitation of the magnetic member, and preferably ensures the stable operation of the starting trigger device based on a magnetic pneumatic switch.

[0036] Please refer to Figures 1 to 4 , In one embodiment, the magnetic pneumatic switch 300 further includes a metal ring 350. Further, the peripheral edge of the pneumatic membrane 320 is connected to the inner wall of the metal ring 350, and the outer wall of the metal ring 350 is connected to the inner wall of the housing 310. Further, the metal ring is a copper ring, which preferably ensures the stable setting of the pneumatic membrane.

[0037] It can be understood that since the pneumatic membrane needs to communicate with the air flow channel through the ventilation hole, and the air flow channel is also the circulation channel of the atomization medium aerosol, a relatively large amount of atomization medium will accumulate at the pneumatic membrane, including liquid leakage and condensate. If the atomization medium accumulates on the pneumatic membrane for a long time, it will affect the response sensitivity of the pneumatic membrane. That is, in the initial stage of using the electronic cigarette, when the inhalation force is small, a relatively large amount of atomization medium aerosol can be aspirated. However, as the use time of the electronic cigarette gradually increases, an increase in the inhalation force will instead result in a decrease in the atomization amount of the aspirated atomization medium aerosol, affecting the user experience. Therefore, please also refer to Figures 1 to 4 , in one embodiment, the air flow channel 201 includes a main channel 2011, an auxiliary channel 2012, and a communication channel 2013. The main channel 2011 and the auxiliary channel 2012 are arranged in a staggered manner. The communication channel 2013 is respectively arranged in a cross manner with the main channel 2011 and the auxiliary channel 2012, and the communication channel 2013 is respectively communicated with the main channel 2011 and the auxiliary channel 2012. The outer shell 310 is arranged at the auxiliary channel 2012, and the ventilation hole 301 is arranged towards the communication channel 2013. In this way, during the suction process, the effective driving and elastic fluttering of the pneumatic membrane 320 are realized, and the pneumatic membrane 320 is arranged in a staggered manner with respect to the main channel 2011 where the atomization medium aerosol is mainly formed, preferably avoiding the accumulation of the leaked atomization medium at the pneumatic membrane 320, and preferably reducing the accumulation of the condensate of the atomization medium aerosol at the pneumatic membrane 320, thereby further improving the start-up stability of the start trigger device 10 based on the magnetic pneumatic switch during long-term use.

[0038] Please also refer to Figures 1 to 4 , in one embodiment, the magnetic pneumatic switch 300 further includes an insulating mounting ring 360. The peripheral wall of the metal ring 350 is connected to the insulating mounting ring 360, and the outer wall of the insulating mounting ring 360 abuts against the inner wall of the outer shell 310.

[0039] It can also be understood that even though the ventilation hole is preferably separated from the signal processing component by using the pneumatic membrane, in fact, the sealing performance of the installation between the pneumatic membrane and the outer shell also has a great impact on the isolation effect between the ventilation hole and the signal processing component. If the connection tightness between the pneumatic membrane and the housing cannot be ensured, it is also difficult to achieve a good isolation effect between the ventilation hole and the signal processing component, that is, the condensate of the atomization medium aerosol will still flow to the signal processing component from the installation gap between the pneumatic membrane and the housing. In this way, during long-term use, there is still a situation that affects the start-up of the atomization device. Therefore, in one embodiment, the metal ring and the insulating mounting ring are of an integrally formed structure, reducing the inflow of condensate from between the pneumatic membrane and the outer shell, thereby further improving the start-up stability of the start trigger device based on the magnetic pneumatic switch during long-term use.

[0040] In one embodiment, the insulating mounting ring is a plastic mounting ring. Further, the plastic mounting ring is an elastic polyurethane plastic mounting ring, an elastic polyamide plastic mounting ring, an elastic polytetrafluoroethylene plastic mounting ring, an elastic polypropylene plastic mounting ring, or an elastic polyethylene plastic mounting ring. Further still, the plastic mounting ring is an elastic polyurethane plastic mounting ring or an elastic polyamide plastic mounting ring, so that the plastic mounting ring has an elastic sealing effect, further reducing the inflow of condensate from between the pneumatic membrane and the housing, and further improving the starting stability of the starting trigger device based on the magnetic pneumatic switch during long-term use.

[0041] If the metal ring and the plastic mounting ring are of an integrally formed structure, it is difficult to assemble the pneumatic membrane onto the metal ring for fixation. Therefore, in order to better reduce the assembly difficulty of the starting trigger device based on the magnetic pneumatic switch and thus improve the assembly efficiency of the starting trigger device based on the magnetic pneumatic switch, please refer to Figures 5 to 7 , in one embodiment, the insulating mounting ring 360 includes a first mounting ring 361 and a second mounting ring 362. The metal ring 350 is clamped between the first mounting ring 361 and the second mounting ring 362. The outer walls of the first mounting ring 361 and the second mounting ring 362 are both connected to the inner wall of the housing 200, and the side of the first mounting ring 361 away from the metal ring 350 abuts against the housing 200, and the side of the second mounting ring 362 away from the metal ring 350 abuts against the housing 200. Further, in one embodiment, the side of the second mounting ring 362 away from the metal ring 350 abuts against one side of the signal processing member 340, and the other side of the signal processing member 340 abuts against the housing 200, so that the side of the second mounting ring 362 away from the metal ring 350 abuts against the housing 200 through the signal processing member 340. In another embodiment, a convex rib is protruded on the inner side of the housing, and the side of the second mounting ring away from the metal ring abuts against the convex rib.

[0042] Please refer to Figures 5 to 7 , in one embodiment, the insulating mounting ring 360 is disposed on the side of the signal processing member 340 close to the pneumatic membrane 320, and the signal processing member 340 is clamped between the insulating mounting ring 360 and the housing 200.

[0043] In one embodiment, the signal processing member includes a board core and an electromagnetic inductor. The board core and the electromagnetic inductor are both built into the housing. The electromagnetic inductor is electrically connected to the board core, the electromagnetic inductor is disposed opposite to the magnetic field generating member, and the board core is electrically connected to the e-cigarette PCB board. Further, the board core is of a circuit board structure.

[0044] It can also be understood that even if the main channel and the auxiliary channel are arranged in a staggered manner to realize the staggered arrangement of the start trigger device based on the magnetic pneumatic switch and the main channel, in fact, since the main channel and the auxiliary channel are still connected, if it is aimed at the leaked atomized medium, it can better prevent it from entering the shell, and if it is aimed at condensed liquid, since the aerosol of the atomized medium will fill the entire airflow channel during the inhalation, condensed liquid will still accumulate inside the shell during the long-term use of the electronic cigarette, and will still affect the response sensitivity of the pneumatic membrane. Therefore, please refer to Figures 5 to 7 In one embodiment, the outer periphery of the pneumatic membrane 320 is sleeved on the metal ring 350, and the pneumatic membrane 320 is blocked at one end of the metal ring 350 near the vent hole 301. Further, the housing 310 is provided with an inclined hole 302, one end of the inclined hole 302 is connected with the pneumatic membrane 320, and the end of the inclined hole 302 away from the pneumatic membrane 320 extends in the direction of gravity, that is, the end of the inclined hole 302 away from the pneumatic membrane 320 extends downward in the direction of gravity. Further, the end of the first mounting ring 361 near the metal ring 350 is provided with an overflow notch 303, and the overflow notch 303 is connected with one end of the inclined hole 302 near the pneumatic membrane 320. Further, the end of the metal ring 350 near the first mounting ring 361 is provided with a wedge surface 304, the wedge surface 304 is set away from the pneumatic membrane 320, and the pneumatic membrane 320 is sleeved on the wedge surface 304, and the wedge surface 304 is connected with the inclined opening. It can be understood that the overflow notch 303, the wedge surface 304 and the inclined hole 302 are interconnected, and the first mounting ring 361 of the overflow notch 303 is close to one end of the metal ring 350, and cooperates with the pneumatic membrane 320 to block one end of the metal ring 350 close to the vent hole 301. Even if the condensate accumulates in the pneumatic membrane 320, the condensate will flow out to the auxiliary channel 2012 in time through the overflow notch 303, the wedge surface 304 and the inclined hole 302 under the action of gravity, thereby further reducing the condensate flowing into between the pneumatic membrane 320 and the housing 310, thereby further improving the starting stability of the starting trigger device 10 based on the magnetic pneumatic switch under long-term use.

The atomization device includes an atomization structure, a power supply structure, and a start trigger device based on a magnetic pneumatic switch of any of the above embodiments. The atomization structure is built into the housing, and the atomization structure is connected to the airflow channel.

Figures 1 to 4, in this embodiment, the start trigger device 10 based on the magnetic pneumatic switch includes an e-cigarette PCB board 100 and a housing 200. The e-cigarette PCB board 100 is built into the housing 200. The housing 200 is provided with an air flow channel 201 and also includes a magnetic pneumatic switch 300. The magnetic pneumatic switch 300 includes a housing 310, a pneumatic membrane 320, a magnetic field generating member 330 and a signal processing member 340. The housing 310 is built into the housing 200, and at least one ventilation hole 301 is provided on the housing 310. The ventilation hole 301 is communicated with the air flow channel 201, and the ventilation hole 301 is located on one side of the pneumatic membrane 320 and communicated with the pneumatic membrane 320.
