DETAILED DESCRIPTION

[0033] The present invention is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are intended to enable the present application to be better understood. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, and methods. In some cases, some operations related to the present application are not shown or described in the specification, in order to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0034] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various implementations. At the same time, the steps or actions in the method description can also be interchanged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for the purpose of clearly describing a certain embodiment and are not meant to be a required sequence, unless otherwise specified that a certain sequence must be followed.

[0035] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0036] Electric heating atomization devices, such as heat-not-burn tobacco products, electronic liquid tobacco products, aromatherapy machines, and drug atomization devices, mostly use buttons set on the outer shell to start the device, requiring the user to install the heated component into the heating chamber and then use the button to start the device. The buttons have problems such as misoperation and service life, which makes them inconvenient for users and cannot meet user needs.

[0037] In the present application, the heated part contains an aerosol matrix, which is heated and atomized to produce an aerosol. The heated part is determined according to the implementation mode of the atomization device. For example, when the atomization device is a heat-not-burn smoking device, the heated part corresponds to a cigarette or a cigarette cartridge. Of course, the above examples are only to illustrate the implementable methods, and do not limit the atomization device to a heat-not-burn smoking device. This application is only for the convenience of description, and takes the heat-not-burn smoking device as an example. At this time, the heated part is a solid cigarette or a cigarette cartridge. For example, when the atomization device is a drug atomization device, the heated part is a solid part containing a drug.

[0038] like Figure 1 As shown, an atomization device is provided in an embodiment of the present application, which may include a power supply component 200 and an atomizer 100.

[0039] The power supply component 200 is used to supply power to the heating element 10 under the triggering of the pressure signal. For example, the power supply component 200 may include a battery and a circuit board. A control module may be provided on the circuit board. The control module controls the power supply component 200 to supply power to the heating element 10 under the triggering of the pressure signal. Alternatively, the power supply component 200 has an electronic switch (such as a MOS tube), the battery is electrically connected to the heating element 10 through the electronic switch, and the output end of the pressure sensor 40 is electrically connected to the control end of the electronic switch. When the pressure sensor 40 outputs a pressure signal to the control end, the electronic switch is turned on, thereby connecting the battery to the heating element 10, and the battery supplies power to the heating element 10. The present application does not limit how the power supply component 200 supplies power to the heating element 10. The above examples are intended to illustrate feasible methods, and other feasible methods are not excluded.

[0040] The atomizer 100 is used to heat the heated component 300 to generate an aerosol. The atomizer 100 provided in the embodiment of the present application is described in detail below.

[0041] like Figure 2 and Figure 3 As shown, an embodiment of the present application provides an atomizer 100, which is applied to an atomization device. The atomization device may include a power supply component 200; the atomizer 100 may include: a heating element 10, a base component 20, a protective cover 30 and a pressure sensor 40.

[0042] like Figure 4 and Figure 5As shown, the base assembly 20 has a heating chamber 201, and the heating element 10 is arranged in the heating chamber 201. For example, a cigarette cartridge can be inserted into the heating chamber 201, and a through hole can be provided at the bottom of the heating chamber 201 to connect the heating chamber 201 with a gas channel or the atmosphere. For example, when a user smokes a cigarette, an airflow can be formed, and the airflow flows from the bottom of the heating chamber 201 to its opening direction.

[0043] like Figures 3 to 6 As shown, the protective cover 30 has a protruding elastic structure 31 . The protective cover 30 is sleeved on the outer periphery of the pressure sensor 40 . The elastic structure 31 is arranged close to the pressure diaphragm 41 of the pressure sensor 40 .

[0044] like Figure 4 and Figure 5 As shown, the protective cover 30 and the pressure sensor 40 are fixed to the base assembly 20, and part or all of the elastic structure 31 extends into the heating chamber 201. Figures 3 to 6 As shown, the elastic structure 31 may have an inclined surface or an arc surface, which is used to guide the elastic structure 31 to be pressed when the heated component 300 contacts and is squeezed, and does not hinder the heated component 300 from being inserted into the bottom of the heating chamber 201, so that the heated component 300 can be installed in place without obstacles.

[0045] The heating cavity 201 is used to install the heated component 300. The heating cavity 201 corresponds to the cavity area inside the base assembly 20, which can accommodate the heating element 10. The heated component 300 can be as shown in FIG. Figure 2 and Figure 4 As shown, the member to be heated 300 is inserted into the heating chamber 201 and has an aerosol matrix.

[0046] The heating element 10 is used to heat the heated component 300 to generate aerosol; the heating element 10 may be a resistive heating element that generates heat when powered on, or an electromagnetic heating element.

[0047] The elastic structure 31 is used to be squeezed by the heated component 300 and the pressure diaphragm 41 when the heated component 300 is installed in the heating chamber 201, and the pressure sensor 40 outputs a pressure signal; the pressure signal is used to trigger the power supply component 200 of the atomization device to supply power to the heating element 10.

[0048] In some embodiments, the elastic structure 31 is also used to perform elastic reset when the heated component 300 is taken out of the heating chamber 201, so as to release the pressure on the pressure diaphragm 41 and the pressure sensor 40 stops outputting the pressure signal.

[0049] After the user inserts the heated part 300, the elastic structure 31 is squeezed by the heated part 300, and the pressure diaphragm 41 is squeezed by the elastic structure 31, triggering the pressure sensor 40 to generate a pressure signal, and the power supply component 200 starts to supply power to the heating element 10, and the heating element 10 starts to heat the heated part 300, and the heated part 300 generates aerosol. When the aerosol matrix of the heated part 300 is consumed, the user pulls out the heated part 300, the elastic structure 31 resets, releases the squeezing of the pressure diaphragm 41, the pressure sensor 40 stops outputting the pressure signal, the power supply component 200 stops supplying power, and the heating element 10 stops heating.

[0050] For example, the pressure sensor 40 can be a microphone, which is a pressure sensor 40 for detecting air pressure or airflow, generally detecting the airflow generated by the user's inhalation. In the present application, it can be used as a switch. The top pressure diaphragm 41 (microphone diaphragm) of the microphone is protected by the protective cover 30, and can also be sealed and heat-insulated. It is tightly fixed on the base assembly 20 and electrically connected to the PCBA control board (power supply assembly 200) through a wire; when the cigarette cartridge is inserted into the cigarette cartridge compartment (heating chamber 201), the cigarette cartridge squeezes the elastic structure 31 of the protective cover 30, the space in the front cavity of the microphone is compressed, the microphone diaphragm is squeezed, the start function is triggered, and the smoking device starts; when the cigarette cartridge is taken out of the cigarette cartridge compartment, the elastic structure 31 of the protective cover 30 is reset, the squeezing force on the microphone diaphragm disappears, and the smoking device stops working.

[0051] like Figure 5 As shown, in some embodiments, the pressure sensor 40 is closer to the bottom of the heating chamber 201 than the heating element 10. The bottom of the heating chamber 201 may be provided with a through hole, which is used to connect the heating chamber 201 with the gas channel or the atmosphere. When heating and atomizing are performed, the airflow flows into the bottom of the heating chamber 201 through the through hole, and the aerosol is brought out of the atomizer 100. Figure 5 In the up-down direction shown, the airflow flows from bottom to top, and the temperature near the bottom of the heating chamber 201 is lower, so the temperature of the working environment of the pressure sensor 40 can be controlled in a lower range and can work normally. At the same time, the protective cover 30 can also avoid high-temperature aging and maintain the elasticity of the elastic structure 31 to ensure that after the heated component 300 is taken out, it can be reset, the pressure diaphragm 41 is not squeezed, and the power supply component 200 stops supplying power to the heating element 10.

[0052] like Figure 5 and Figure 6As shown, in some embodiments, the base assembly 20 is provided with a window structure 211 at the bottom near the heating chamber 201, for example, at the side wall near the bottom; the window structure 211 connects the space for installing the pressure sensor 40 with the heating chamber 201. After the pressure sensor 40 with the protective cover 30 is installed on the base assembly 20, the elastic structure 31 extends into the heating chamber 201 through the window structure 211, and the protective cover 30 blocks the window structure 211 to separate the pressure sensor 40 from the heating chamber 201. The hot air flow or aerosol will not directly act on the pressure sensor 40, and the protective cover 30 achieves a protective function.

[0053] like Figure 3 and Figure 5 As shown, in some embodiments, the heating element 10 may be a tubular heating element or a mesh heating element; the heating element 10 has a hollow area so that the heated component 300 passes through the heating element 10 .

[0054] For example, general heat-not-burn smoking devices mostly use a heating needle, which is arranged at the bottom of the heating chamber 201. The hot aerosol flows upward from the bottom, and there is a high-temperature airflow in the heating chamber 201 as a whole. At this time, it is difficult to directly arrange the pressure sensor 40 on the inner or outer wall of the heating chamber 201. Generally, a more complex transmission structure needs to be set up, which will increase the volume of the atomizer 100, especially the electronic cigarette, which will greatly affect the user experience.

[0055] The present application adopts a tubular heating element or a mesh heating element. The mesh heating element is rolled into a tube when used, and the middle area is hollow. It can be set on the periphery of the heated part 300, so that the heating element 10 can be set at a relatively far position, and the pressure sensor 40 is closer to the bottom of the heating chamber 201. The airflow through the bottom through hole ensures that it works at a lower temperature.

[0056] like Figures 3 to 5 As shown, in some embodiments, the base assembly 20 may include a lower base 21 and an upper shell 22; the lower base 21 has a first mounting portion, the upper shell 22 has a second mounting portion, the two ends of the heating element 10 are respectively fixed by the first mounting portion and the second mounting portion, and the middle area of ​​the heating element 10 is suspended.

[0057] like Figure 5 As shown, the temperature of the upper and lower ends of the heating element 10 is lower than that of the middle area, and the base assembly 20 can fix the two ends, for example, by using a circular groove with a protrusion as shown in the figure, and the ends of the heating element 10 are embedded in the groove and are limited by the protrusion, thereby achieving fixation. The above is a form in which the heating element 10 is embedded in the first mounting part and the second mounting part, and it can also be in the form of a jacket on the first mounting part and the second mounting part.

[0058] like Figure 6As shown, in some embodiments, the protective cover 30 has a cavity 32 matching the pressure sensor 40. After the pressure sensor 40 is installed in the cavity 32, the protective cover 30 at least covers the pressure diaphragm 41 of the pressure sensor 40. The protective cover 30 can be configured to match the shape of the pressure sensor 40, tightly wrapping the top surface and part or all of the side surfaces of the pressure sensor 40 to protect the pressure diaphragm 41.

[0059] In some embodiments, the protective cover 30 is made of elastic heat-resistant material, for example, insulating material, such as heat-resistant silicone or heat-resistant elastic rubber. Generally, high-temperature resistant polymer materials have good elasticity and good heat insulation effect, which can provide better protection for the pressure sensor.

[0060] In summary, the atomizer 100 and the atomization device provided in the present application use a protective cover 30 to protect the pressure sensor 40, and a resettable elastic structure 31 to extend into the heating chamber 201, so as to cooperate with the installation and removal of the heating component 300 such as a cigarette cartridge to achieve the effect of self-starting and self-stopping, which is convenient to use and improves the user experience.
