[0002] The electronic atomization device generally includes a pneumatic switch, which can detect the change in air pressure when air flow occurs in the air path within the electronic atomization device, and control the corresponding circuit to start when the air pressure change meets the conditions.

[0003] Some electronic atomizer devices are equipped with child locks to prevent children from starting the electronic atomizer devices. Some current child lock solutions include: 1. Adding a chip to the pneumatic switch to control the opening and closing of the child lock by changing the frequency of continuous puffing (for example, unlocking by continuous puffing for 5 seconds); 2. Using an onboard button solution to turn the child lock function on and off by triggering the button multiple times (for example, unlocking by pressing the button 5 times in a row); 3. Turning the child lock function on and off by identifying the number of times the atomizer is plugged in and out in a short period of time (for example, unlocking by plugging in and out the atomizer 3-5 times in a row).

[0004] However, Solution 1 may lead to a poor consumer experience, as it is often difficult to turn the child lock on and off; Solution 2 requires adding PCBA, adding button functions, and requiring multiple consecutive button presses, which is costly, inconvenient to use, and has a poor experience; and Solution 3 also requires PCBA logic control, and the experience of continuously plugging and unplugging the cartridge is also poor and inconvenient to use.

[0055] The guide member 220 is installed inside the cylindrical part of the sealing connection seat 250, and is provided with an oil inlet channel 221 and an aerosol channel 222. Please refer to 2, Figure 3 , Figure 5 and Figure 6 The oil inlet channel 221 and the aerosol channel 222 are arranged crosswise. The oil inlet channel 221 forms a liquid guide hole on the top surface of the guide member 220. The liquid guide hole is connected to the liquid storage tank 213, and can allow the atomized matrix in the liquid storage tank 213 to flow in. Two corresponding openings are provided on the closed part of the sealing connection seat 250. The oil inlet channel 221 can guide the atomized matrix to the heating body 231, so that the atomized matrix is ​​heated when the heating body 231 generates heat to generate an aerosol. The aerosol channel 222 forms an atomized material outlet on the top surface of the guide member 220. The atomized material outlet can be connected to the central tube 212 of the suction nozzle 210. The lower end of the aerosol channel 222 is connected to the atomization chamber 240 around the heating core, and can allow the aerosol generated by atomization to be discharged. Please refer to Figure 3 In one embodiment, the guide member 220 can be fixed to the top of the core support 260 by a snap-fit ​​structure. Of course, the guide member 220 can also be fixed in other ways, such as being fixed in the sealing connection seat 250 by interference fit.

[0056] In one embodiment, the heating body 231 can be a ceramic heating body 231, which is connected to a power supply component, such as a battery unit, through a terminal 232, and can generate a certain amount of heat to heat the atomized substrate when powered on. Figures 2 to 4 The top of the core support 260 is provided with a heating body installation cavity, and the heating body 231 is arranged in the heating body installation cavity. The portion of the top of the core support 260 provided with the heating body installation cavity constitutes a heating seat 261. The heating seat 261, the heating body 231 and the guide member 220 can constitute a heating module, and the heating module generates heat when powered on to heat the atomized substrate.

[0058] In one embodiment, the electronic atomization device further includes a switch mounting seat 262 for mounting a pneumatic switch 270. The switch mounting seat 262 and the heating module are arranged in a hollow inner cavity of the device housing 100 at intervals. The switch mounting seat 262 and the heating module are sealed and connected to the inner wall of the hollow inner cavity. The switch mounting seat 262, the heating module and the device housing 100 form an air chamber, which constitutes a part of the suction channel. In order to ensure the seal between the switch mounting seat 262 and the heating module and the inner wall of the hollow inner cavity, in one embodiment, a sealing ring 263 is provided on the radial outer side of the switch mounting seat 262 and the heating module, and the sealing is achieved by the sealing ring 263. By using the air chamber formed by the switch mounting seat 262, the heating module and the device housing 100 to form a part of the suction channel, it is possible to avoid setting a separate suction channel in the corresponding part, which has a simple structure and is conducive to reducing costs.

[0059] The suction channel is used for the suction airflow to enter the heating module. Of course, the heating module may be provided with a corresponding air chamber communication hole 2611. The air chamber communication hole 2611 may be, for example, Figure 2 and Figure 3 The through hole is located at the top center of the core support 260; in addition, the suction channel has a working air inlet for normal suction airflow to enter, and the working air inlet will be introduced below.

[0060] The pneumatic switch 270 is arranged corresponding to the suction channel, and the pneumatic switch 270 is used to generate a switching action according to the gas pressure of the suction channel. Specifically, in one embodiment, the upper and lower end faces of the pneumatic switch 270 are respectively a low-pressure side and a normal-pressure side, the low-pressure side is connected to the space on the side of the switch mounting seat 262 close to the heating module, that is, the hollow inner cavity, and the normal-pressure side is connected to the atmosphere. When the pressure difference between the low-pressure side and the normal-pressure side reaches a set value, the pneumatic switch 270 generates a switching action, for example, the internal circuit is switched from disconnection to connection, so that the circuit of the heating body 231 is turned on, and the heating of the atomized substrate is realized. When the switch mounting seat 262 is arranged in the device housing 100, the pneumatic switch 270 can be arranged on the side of the switch mounting seat 262 close to the heating module, and the switch mounting seat 262 is provided with a normal-pressure side connecting hole 2621, and the normal-pressure side connecting hole 2621 passes through the switch mounting seat 262 in the up and down direction.

[0061] In order to connect the suction channel to the atmosphere, an air inlet hole 2622 is provided on the switch mounting seat 262, and the air inlet hole 2622 connects the hollow inner cavity with the atmosphere. In addition, an air inlet control port 130 is provided on the device housing 100, and the air inlet control port 130 is exposed on the surface of the device housing 100 for the user to block and open, and the air inlet control port 130 is connected to the suction channel. In one embodiment, at least a part of the channel wall of the suction channel is formed by the device housing 100. According to this structure, the air inlet control port 130 is a through hole provided on the device housing 100, and the inner end opening of the through hole is connected to the suction channel, which has a simple structure, is easy to manufacture, and is conducive to cost control. Of course, in some other embodiments, the air inlet control port 130 can also be connected to the heating element by other means, such as through an air pipe to the heating element, and another example is through the air path formed by the through hole inside the corresponding component to the heating element.

[0062] In addition, the device housing 100 includes a sealing plate 120 disposed at one end away from the heating module, the switch mounting seat 262 and the sealing plate 120 are arranged at intervals, and the space between the switch mounting seat 262 and the sealing plate 120 forms a connecting cavity 300; the sealing plate 120 is provided with an atmospheric connecting hole 121, the atmospheric connecting hole 121 constitutes a working air inlet, and the atmospheric connecting hole 121, the atmospheric pressure side connecting hole and the air inlet hole 2622 are all connected to the connecting cavity 300. When installing the atomizer core assembly 200, after the atomizer core assembly 200 is installed in place in the device housing 100, the space between the switch mounting seat 262 and the sealing plate 120 can play a connecting role, and the conduction of the airflow path can be easily realized.

[0063] In one embodiment, please refer to Figures 2 to 4The upper and lower ends of the core support 260 of the electronic atomization device are respectively provided with a heating seat 261 and a switch mounting seat 262, and the heating seat 261 and the switch mounting seat 262 are both sealed and connected to the inner wall of the hollow inner cavity; the core support 260 also includes an intermediate connector 264 located between the heating seat 261 and the switch mounting seat 262. The core support 260 adopts the above structure to facilitate the assembly of the atomization core assembly 200, with good integrity and compact structure. In a specific embodiment, please refer to Figure 4 The cross section of the intermediate connecting body 264 is an arc-shaped structure, and the air intake control port 130 is arranged at a position of the device housing 100 corresponding to the opening of the arc-shaped structure.

[0064] At the same time, since the air chamber surrounded by the switch mounting seat 262, the heating module and the device housing 100 is used to form a part of the suction channel, in order to facilitate the installation of the battery unit 400, there is an installation space between the heating seat 261 and the switch mounting seat 262, and the battery unit 400 is arranged in the installation space. There is a gap between the battery unit 400 and the intermediate connector 264 and / or the device housing 100, and the gap is for the airflow to flow from the switch mounting seat 262 to the heating module, which can take into account the installation requirements of the battery unit 400 and the circulation requirements of the suction airflow. In addition, the heating body 231 on the heating seat 261 and the pneumatic switch 270 on the switch mounting seat 262 need to be connected to the battery unit 400, and the battery unit 400 is arranged in the above-mentioned installation space, which also facilitates the electrical connection between the heating body 231 and the pneumatic switch 270. In some other embodiments, the intermediate connector 264 can also be in other forms, such as a columnar connector or a sheet connector distributed along the circumference of the device housing 100.

[0065] It should be noted that the shape, size and number of the working air inlet and the air inlet control port 130 are not limited, and the setting position can also be adjusted according to the structural design of the electronic atomization device. In one embodiment, the air inlet control port 130 is set on the side of the rod body part of the device housing 100, and can be set in the axial middle part of the rod body part, taking full account of the consumer's usage habits. When the user holds the electronic atomization device, the air inlet control port 130 can be conveniently blocked by hand.

[0066] In addition, in one embodiment, the electronic atomization device may include a blocking patch (not shown in the figure), which is used to be bonded to the device housing 100 to block the air inlet control port 130. The material, shape and thickness of the blocking patch are not limited, and it can be a sticker, a plastic sheet, a silicone sheet, etc., and can be attached to the device housing 100 and block the air inlet control port 130 according to the user's preference.

[0067] When in use, the air inlet control port 130 is normally in an open state. When a child takes the electronic atomizer device, even if they inhale, since the air inlet control port 130 and the working air inlet port can inhale air at the same time, it is possible to avoid a significant drop in the air pressure in the suction channel. The pressure difference at the pneumatic switch 270 is limited, and thus cannot meet the pressure difference required to start the electronic atomizer device. The electronic atomizer device will not start, thereby achieving the purpose of the child lock. When an adult needs to inhale, he can just block the air inlet control port 130 with his fingers, or use the sealing patch or other items provided with the host of the electronic atomizer device to cover the air inlet control port 130, and then he can inhale normally. The airflow path is as follows: Figure 2 and Figure 3 As shown, the channel corresponding to the airflow path is the suction channel.

[0068] It should be noted that in some other embodiments, when the heating module and the suction channel of the electronic atomization device adopt other structural forms, the air intake control port 130 can still be provided, and the child lock function is realized by controlling the opening and closing of the air intake control port 130. In addition, the pneumatic switch can also detect the pressure of the suction channel and cooperate with the adapter circuit to realize the switch function.

[0069] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
