Description

Technical Field

[0001] This invention relates to the field of aerosol generation device control technology, and particularly to an aerosol generation device. Background Technology

[0002] Aerosol generators are products that use atomization or other methods to vaporize an aerosol matrix, which is then inhaled by the user. Most existing aerosol generators, limited by cost, lack pre-activation safety features. Users can activate the aerosol generator without any activation steps, and even under certain environmental conditions or factors, such as pressure changes or impacts, it can operate without user intervention. Therefore, these types of aerosol generators pose safety hazards. To mitigate these potential risks, and given that the atomizer operates on a battery, some aerosol generators incorporate pre-activation safety features on the battery itself. For example, pressing and holding the start button on the battery unlocks it, allowing the battery to supply power to the atomizer. However, implementing pre-activation safety features on the battery itself presents challenges due to complex circuitry and high costs. Summary of the Invention

[0026] Example 1

[0027] refer to Figure 1 The diagram illustrates a principle block diagram of an aerosol generating device according to an embodiment of the present invention.

[0028] As an example, the device includes an atomizing component 1 and a battery component 2. The atomizing component 1 includes a heating element 101, a first electrical connection unit 102, a second electrical connection unit 103, and a protection component 104. The heating element 101 is electrically connected to the positive electrode of the battery component 2 via the first electrical connection unit 102 and to the negative electrode of the battery component 2 via the second electrical connection unit 103, for heating the atomizing liquid to form an aerosol. The protection component 104 is electrically connected to the heating element 101 in parallel and is disposed between the first electrical connection unit 102 and the second electrical connection unit 103, for switching the connection state between the first electrical connection unit 102 and the second electrical connection unit 103.

[0029] Optionally, the first electrical connection unit 102 and the second electrical connection unit 103 can be electrode contacts, pins, and / or electrodes at the bottom of the atomizing assembly at both ends of the heating element 101. Here, the first electrical connection unit 102 and the second electrical connection unit 103 are used as the pins of the heating element 101. As shown in the figure, the heating element 101 and the protection assembly 104 are electrically connected in parallel and positioned between the first electrical connection unit 102 and the second electrical connection unit 103. The heating element 101 and the protection assembly 104 are electrically connected to the positive terminal of the battery assembly 2 through the first electrical connection unit 102, and the heating element 101 and the protection assembly 104 are electrically connected to the negative terminal of the battery assembly 2 through the second electrical connection unit 103. It should be noted that the heating element 101 and the protection assembly 104 can also be electrically connected to the negative terminal of the battery assembly 2 through the first electrical connection unit 102, and the heating element 101 and the protection assembly 104 can also be electrically connected to the positive terminal of the battery assembly 2 through the second electrical connection unit 103; this is not a limitation.

[0030] Optionally, the upper part of the protection component 104 is an actuator 1041, and the lower part is a conductor 1042, with the actuator 1041 and conductor 1042 connected. The conductor 1042 is made of metal and is used to drive the protection component to switch between a closed and open circuit state; the actuator 1041 is made of rigid material and is used to cut off the protection component. That is, the conductor 1042 in the lower part of the protection component 104 is made of metal and is conductive, while the actuator 1041 in the upper part of the protection component 104 can be made of metal or non-metal, meaning it can be conductive or non-conductive. Specifically, in actual implementation, by placing the protection component 104 inside the atomizing component 1, the liquid storage chamber can be kept closed, thus preventing the aerosol generating device from malfunctioning due to external factors during transportation. However, since there may be insufficient sealing between the protection component 104 and the atomizing airway, the conductive element 1042 located in the lower half of the protection component 104 is conductive, which will cause the circuit where the protection component 104 is located to be in a conductive state. The circuit formed by the atomizing component and the battery device will be in a short-circuit state. That is, this will cause the heating element 101 connected in parallel to it to be in a short-circuit state. At this time, after the battery device detects the short-circuit state of the circuit, it will shut off the power output from the battery device to the atomizer. In other words, the aerosol generating device cannot work normally at this time, which further improves the safety of the aerosol generating device.

[0031] Optionally, the protection component 104 is further configured to switch between a closed-circuit state where the first electrical connection unit 102 and the second electrical connection unit 103 are connected, and a closed-circuit state where the electrical connection between the first electrical connection unit 102 and the second electrical connection unit 103 is disconnected. Specifically, when the protection component 104 is in the closed-circuit state, the first electrical connection unit 102 and the second electrical connection unit 103 are connected, and the circuit formed by the atomizing component 1 and the battery component 2 is in a short-circuit state. After detecting the short-circuit state, the battery component 2 shuts off the power output from the battery component 2 to the atomizing component 1. When the movable actuator 1041 drives the conductive member 1042, the conductive member 1042 disconnects the electrical connection between the first electrical connection unit 102 and the second electrical connection unit 103, the protection component 104 switches to the closed-circuit state, and the battery component 1, after detecting that the circuit resistance is normal, acts to unlock the state, allowing the output of power to the atomizing component 2. That is, when the protection component 104 is pulled away from the atomizing component 1 during actual use of the aerosol generating device, the protection component 104 disconnects the electrical connection between the first electrical connection unit 102 and the second electrical connection unit 103. In other words, the circuit where the protection component 104 is located is in an open circuit state. When the battery component 2 detects that the circuit resistance is normal, it will act to unlock the state and allow the output of electrical energy to the atomizer. At this time, the aerosol generating device can work normally.

[0032] Optionally, when the protection component 104 originally has a complete circuit and is in a closed state, the conductive element 1042 and the actuator 1041 included in the protection component 104 can be metal rods. In this way, during processing, the actuator 1041 and the conductive element 1042 of the protection component 104 are integrally formed. This design can greatly simplify the production and assembly steps and is beneficial for mass production. Optionally, the actuator 1041 can be a rod made of other rigid materials, such as a wooden rod. In this case, moving the actuator 1041 drives part or all of the protection component 104 to move, causing a partial circuit break or the entire protection structure to disconnect from the circuit, switching the protection structure to an open-circuit state. That is, the complete circuit of the protection component 104 at this time is all located on the conductive element 1042.

[0033] Optionally, when the protection component 104 originally has a complete circuit and is in a closed state, the conductive element 1042 included in the protection component 104 can be a metal rod. When the actuator 1041 is also a metal rod, moving the actuator 1041 drives part or all of the protection component 104 to move, causing a partial circuit on the protection component 104 to be disconnected or the entire protection structure to be disconnected from the circuit, and the protection structure switches to an open state. That is, at this time, part of the complete circuit of the protection component 104 is placed in the conductive element 1042, and another part is placed in the braking element. The actuator 1041 is connected to the conductive element 1042 to form a complete circuit. The protection component is in a closed state. When the actuator 1041 is moved, the circuit on the protection component is cut off, and the protection structure switches to an open state.

[0034] like Figure 4 The diagram shows the structure of the protection component 104. The upper part is the actuator 1041, and the lower part is the conductor 1042. The actuator 1041 and the conductor 1042 are engaged. The actuator 1041 has a groove or protrusion at its bottom, and the conductor 1042 has a protrusion or groove at its top, allowing them to cooperate and reducing production costs, making removal easier. A pull rod seal 1043 is provided at the actuator 1041 of the protection component, which can effectively prevent the aerosol matrix from leaking out of the smoke outlet. It can also prevent outside air from entering the aerosol generating device through the gap between the heating element of the atomizing core and the pull rod, thus preventing the sensor from being mistakenly triggered during the delivery process and heating and atomizing the e-liquid.

[0035] like Figure 2-3 The diagram shows a schematic representation of an aerosol generating apparatus according to an embodiment of the present invention.

[0036] As an example, the atomizing assembly 1 further includes an upper housing 105, an atomizing channel 106, an atomizing core 107, and a bottom cover 108. The upper outer peripheral wall of the bottom cover 108 is used to connect and assemble with the inner peripheral wall of the upper housing 105 to form the atomizing assembly 1. The atomizing channel 106 is coaxially arranged with the upper housing 105 and is connected to the top of the upper housing 105. The protective assembly 104 passes through the atomizing channel 106 and the atomizing core 107 in sequence. The atomizing assembly also includes a liquid-absorbing element 109, which wraps around the heating wire 101, and the heating wire 101 wraps around the protective assembly 104. Specifically, the heating element 101 can be a spiral heating wire or a mesh heating wire, and the liquid absorption element 109 can be ceramic or a cotton wick, preferably a cotton wick with no less than two layers or a coated or thick-film porous ceramic. The atomizing channel 106 is connected to the main air channel to facilitate the extraction of atomized e-liquid for the user to inhale. The upper shell 105 includes a mouthpiece or a mouthpiece independently mounted on the upper shell. The upper shell (outer peripheral wall) is assembled with the lower shell (inner peripheral wall) of the battery assembly 2 by snap-fit, riveting, or threaded connection to form an integral unit. The upper shell 105 (inner peripheral wall) defines the position of the bottom cover 108 in the atomizing assembly 1 and is assembled with the bottom cover 108 by snap-fit, riveting, or threaded connection to form the atomizing assembly.

[0037] As an example, the battery assembly 2 includes a lower housing 201, a battery 202, an inner liner tube 203, a vent tube 204, a sensor seal 205, and a sensor 206. The lower housing 201 is located outside the battery assembly 2 and is assembled with the upper housing (outer peripheral wall) by snap-fit, riveting, or threaded connection to form a single unit. The battery 202 is placed inside the lower housing 201 to provide operating voltage for the atomizing component 1. The vent tube 204 is located at the bottom of the battery assembly 2 for bottom air intake. To prevent deformation during assembly, it is preferably installed using a steel pipe. The liner tube 203 is located inside the vent hole of the sensor seal. The material of the inner liner tube 203 can be PC material. Its upper end is tightly connected to the lower outer peripheral wall of the bottom cover of the atomizing component. The tight connection is sealed by a seal. Its lower end is tightly connected to the sensor seal 205. The sensor seal 205 can be silicone or other plastic parts with sealing function. The lower end of the bottom cover and the sensor seal 205 simultaneously clamp and fix the position of the battery 202. The sensor seal 205 is interference-fitted with the interior of the lower housing 201. The sensor 206 is located at the bottom center of the battery assembly 2.

[0038] The above-disclosed technical solution involves setting a protection component in the atomizing component. Specifically, a protection structure that can switch between a closed circuit state and an open circuit state is set between the first electrical connection unit and the second electrical connection unit of the atomizing component. When the protection structure is in the closed circuit state, it activates the short-circuit protection function of the battery device, thereby cutting off the power output from the battery device to the atomizer.
