Description

Technical Field

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

[0002] Atomizing devices can atomize the atomizing matrix into an aerosol by heating without combustion. To achieve self-starting, existing atomizing devices usually have a sensing component installed on their main air intake channel. When the user inhales, a negative pressure is generated at the sensing component, which is triggered to control the atomizing device to start automatically. However, since the sensing component is located on the main air intake channel, there is a risk that the sensing component will be corroded by condensate. Utility Model Content

[0003] This application provides an atomizing device that can prevent the sensing components from being corroded by condensate and extend the service life of the sensing components.

[0004] This application provides an atomizing device, including a housing assembly, an atomizing assembly, a control circuit board, and a sensing assembly. The housing assembly has an independent air intake channel and a negative pressure channel. The atomizing assembly has an atomizing channel, and both the air intake channel and the negative pressure channel are connected to the atomizing channel. The control circuit board is disposed within the housing assembly, and one side of the control circuit board and the housing assembly form a mounting cavity, which is connected to the negative pressure channel. The control circuit board is electrically connected to the atomizing assembly. The sensing assembly is disposed within the mounting cavity, and the sensing assembly has a sensing channel that is connected to the mounting cavity. The sensing assembly is used to detect the air pressure of the negative pressure channel.

[0005] In an optional embodiment, the negative pressure channel and the air intake channel are arranged laterally spaced along the housing assembly, and the control circuit board is arranged longitudinally along the housing assembly.

[0006] In an optional embodiment, the axis of the sensing channel is a straight line extending laterally along the housing assembly, and the axes of the negative pressure channel and the atomizing channel are both straight lines extending longitudinally along the housing assembly.

[0007] In an optional embodiment, the extended axes of the sensing channel and the negative pressure channel are staggered.

[0008] In an optional embodiment, the sensing component includes an airflow sensor and a sealing sleeve, the sealing sleeve being fitted over the airflow sensor and the sensing channel being formed on the sealing sleeve; the airflow sensor includes a connecting surface and a sensing surface arranged laterally opposite to each other along the housing component, the connecting surface being connected to the control circuit board, and the sensing surface communicating with the mounting cavity through the sensing channel.

[0009] In an optional embodiment, one end of the sensing channel is spaced apart from the sensing surface, and the other end is spaced apart from the cavity wall of the mounting cavity; the negative pressure channel is spaced apart from the outer wall of the sealing sleeve.

[0010] In an optional embodiment, the housing assembly includes a housing and a mounting base, the mounting base being disposed within the housing, one end of the mounting base being sealed to the control circuit board and forming the mounting cavity with the control circuit board, and the negative pressure channel being formed on the mounting base.

[0011] In an optional embodiment, the housing assembly is further provided with an airflow channel, at least a portion of which covers the outlet end of the negative pressure channel, the inlet end of the atomizing channel, and the outlet end of the inlet channel, so that the negative pressure channel, the atomizing channel, and the inlet channel are interconnected through the airflow channel.

[0012] In an optional embodiment, the airflow channel extends laterally along the housing assembly, and along the longitudinal direction of the housing assembly, the negative pressure channel and the air intake channel are located on the same side of the airflow channel, and the atomizing channel is located on the other side of the airflow channel.

[0013] In an optional embodiment, the housing assembly is provided with an air inlet and an adjusting member. The adjusting member is movable relative to the housing assembly to adjust the size of the air inlet, which is used to enable the air intake channel to communicate with the outside air.

[0014] According to this embodiment, the atomizing device includes a housing assembly, an atomizing assembly, a control circuit board, and a sensing assembly. The housing assembly has independent air intake and negative pressure channels. The atomizing assembly has an atomizing channel, and both the air intake and negative pressure channels are connected to the atomizing channel. The control circuit board is located within the housing assembly, and one side of the control circuit board forms a mounting cavity with the housing assembly. The mounting cavity is connected to the negative pressure channel and is electrically connected to the atomizing assembly. The sensing assembly is located within the mounting cavity and has a sensing channel that is connected to the mounting cavity. Because the air intake and negative pressure channels are independent, they do not interfere with each other. Furthermore, since the sensing assembly is connected to the mounting cavity via the sensing channel and then to the atomizing channel via the negative pressure channel, the distance for condensate or atomizing matrix to flow into the sensing assembly is increased. This reduces the impact of condensate or atomizing matrix on the sensing assembly, improves the sensitivity of the sensing assembly, and extends its service life. Meanwhile, the structural design, based on the connection between the sensing channel and the negative pressure channel through the installation cavity, ensures that the installation cavity generates sufficient negative pressure to trigger the sensing component during rapid and large-volume suction, thereby preventing the atomizing device from being accidentally activated and improving the safety of using the atomizing device.

Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0026] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.

[0027] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0028] Atomizing devices are equipment that use the principle of heating without burning to heat the atomizing matrix, which can heat the atomizing matrix to atomize it and generate an aerosol that can be used by users.

[0029] It should be noted that the term "aerosol" in this context refers to a dispersion of solid or liquid particles in a gas. The term "aerosol" as used herein can generally refer to substances that have been vaporized, atomized, sprayed, or jetted, or otherwise transformed from a solid or liquid form into an inhalable form containing suspended solid or liquid drug particles.

[0030] As used herein, the term "atomizing matrix" refers to any suitable compound or mixture of compounds that facilitates the formation of an aerosol (e.g., a stable aerosol that is substantially resistant to thermal degradation at the system's operating temperature) during use. Suitable atomizing matrices are well known in the art and include, but are not limited to: polyols such as triethylene glycol, 1,3-butanediol, and glycerol; esters of polyols such as mono-, di-, or triacetic acid esters of glycerol; and aliphatic esters of mono-, di-, or polycarboxylic acids such as dimethyl dodecanoate and dimethyl tetradecanoate. Atomizing matrices may include nicotine. Atomizing matrices may include water. Atomizing matrices may include glycerol (also known as glycerol) having a higher boiling point than nicotine. Atomizing matrices may include propylene glycol. Atomizing matrices may include plant-based materials. Atomizing matrices may include homogeneous plant substrates. Homogeneous plant substrates may contain volatile compounds. These compounds may be released from the atomizing matrix upon heating.

[0031] The atomizing device includes a housing assembly 100, an atomizing component 200, and a control component 300. The housing assembly 100 can be understood as an assembly that constitutes the overall appearance of the atomizing device. It has multiple cavities inside for installing different parts. For example, the atomizing component 200 and the control component 300 are both located inside the housing assembly 100. The control component 300 includes a battery 310 and a control circuit board 320 that are electrically connected. The control circuit board 320 is electrically connected to the atomizing component 200. The battery 310 can provide the power required for the atomizing component 200 to work, and the control circuit board 320 can control the heating temperature and power of the atomizing component 200, etc.

[0032] The working principle of the atomizing device is that after the atomizing component 200 is powered on, it can heat the atomizing matrix to form an aerosol. When the user inhales, the outside air enters the atomizing component 200 and mixes with the aerosol, and then is inhaled by the user. In order to enable the atomizing device to start automatically during inhalation, the atomizing device also includes a sensing component 400, which can be triggered under negative pressure.

[0033] Based on the above working principle, traditional atomizing devices are equipped with an air intake channel 110 and an atomization channel 210. The two ends of the air intake channel 110 are connected to the outside air and the atomization channel 210, respectively. The sensing component 400 is installed on the air intake channel 110. After the atomizing device is not used, there may be a certain amount of condensate or leaked atomizing matrix inside. The condensate or atomizing matrix can enter the sensing component 400 along the air intake channel 110, thereby affecting the sensitivity of the sensing component 400. In severe cases, it may even damage the sensing component 400 and shorten its service life.

[0034] Please see Figures 1 to 9To address the aforementioned issues, this application provides an atomizing device. Its housing assembly 100 contains an independent air intake channel 110 and a negative pressure channel 120. The atomizing assembly 200 contains an atomizing channel 210. Both the air intake channel 110 and the negative pressure channel 120 are connected to the atomizing channel 210. A control circuit board 320 is disposed within the housing assembly 100, and one side of the control circuit board 320 and the housing assembly 100 enclose a mounting cavity 141. The mounting cavity 141 is connected to the negative pressure channel 120. The control circuit board 320 is electrically connected to the atomizing assembly 200. A sensing component 400 is disposed within the mounting cavity 141. The sensing component 400 has a sensing channel 410 connected to the mounting cavity 141. The sensing component 400 is used to detect the air pressure in the negative pressure channel 120.

[0035] Because the intake channel 110 and negative pressure channel 120 are designed to be independent of each other, they do not interfere with each other. Furthermore, since the sensing component 400 is connected to the mounting cavity 141 via the sensing channel 410 and then to the atomization channel 210 via the negative pressure channel 120, the distance for condensate or atomizing matrix to flow into the sensing component 400 is increased. This reduces the impact of condensate or atomizing matrix on the sensing component 400, effectively protecting it, improving its sensitivity, and extending its service life. Simultaneously, the structural design of the sensing channel 410 and negative pressure channel 120 connected to the mounting cavity 141 ensures that the mounting cavity 141 generates sufficient negative pressure to trigger the sensing component 400 during rapid and high-volume suction, thus preventing accidental activation of the atomizing device and improving its safety.

[0036] In some embodiments, the atomizing assembly 200 further includes a suction end 220, a heating assembly 230, and a liquid storage assembly 240. The liquid storage assembly 240 stores an atomizing matrix and includes a medium (such as a liquid storage cotton) and / or a cavity capable of storing the atomizing matrix. The liquid storage assembly 240 is connected to the atomizing channel 210. The heating assembly 230 is disposed in the atomizing channel 210 and is electrically connected to the control assembly 300. The heating assembly 230 includes a heating tube, a heating mesh, a heating film, or a heating area, and can generate heat after being powered on. The suction end 220 is disposed at the end of the atomizing channel 210 away from the control assembly 300, and the user completes the suction action through the suction end 220.

[0037] In some embodiments, the negative pressure channel 120 and the air intake channel 110 are arranged at X intervals along the lateral side of the housing assembly 100, which can make full use of the internal structural design of the housing assembly 100 and make its arrangement more reasonable and convenient.

[0038] It should be noted that in this embodiment, the horizontal X and vertical Y are perpendicular to each other. According to usage habits, when using an atomizing device, the vertical Y is defined as the vertical direction, which is consistent with the arrangement direction of the suction end 220 and the heating component 230.

[0039] In some embodiments, the axis of the sensing channel 410 is a straight line extending laterally (X) along the housing assembly 100, and the axes of the negative pressure channel 120 and the atomizing channel 210 are both straight lines extending longitudinally (Y) along the housing assembly 100. That is, the axes of the sensing channel 410 and the negative pressure channel 120 are perpendicular to each other. By setting the sensing channel 410, negative pressure channel 120, and atomizing channel 210 to different extending directions and configuring them as a straight-through structure, the negative pressure channel 120 and the sensing channel 410 cannot be aligned. Liquids such as condensate or atomizing matrix can only enter the mounting cavity 141 through the negative pressure channel 120 and cannot directly enter the sensing channel 410, thus preventing contamination or damage to the sensing component 400 and further achieving effective protection for the sensing component 400. Because the axes of the sensing channel 410 and the negative pressure channel 120 are perpendicular to each other, the possibility of condensate or atomizing matrix flowing into the sensing channel 410 is reduced, effectively protecting the sensing component 400 and eliminating the influence of condensate or atomizing matrix on the sensing component 400.

[0040] In some embodiments, the extended axes of the sensing channel 410 and the negative pressure channel 120 are staggered, such as... Figure 4 As shown in the diagram, when the sensor component 400 is cut at the same position, the structural part forming the sensor channel 410 is cut off, while the negative pressure channel 120 is not cut off. This design further increases the difficulty for liquid in the negative pressure channel 120 to enter the sensor channel 410, thus preventing liquid from entering the sensor component 400.

[0041] Please see Figures 2 to 5 In some embodiments, the sensing component 400 includes an airflow sensor 420 and a sealing sleeve 430. The sealing sleeve 430 is fitted over the airflow sensor 420, and a sensing channel 410 is formed on the sealing sleeve 430. The sealing sleeve 430 can protect the airflow sensor 420. The sealing sleeve 430 can be made of silicone material, which is readily available and cost-effective. The airflow sensor 420 can effectively monitor changes in air pressure and transmit the signal to the control circuit board 320. The control circuit board 320 responds accordingly to the signal (such as activating the atomizing component 200).

[0042] To accommodate existing button or touchscreen displays, the control circuit board 320 is positioned along the longitudinal Y-axis of the housing assembly 100, adapting to the location of the display or touchscreen for user convenience. The airflow sensor 420 includes a connecting surface 421 and a sensing surface 422 positioned opposite each other along the transverse X-axis of the housing assembly 100. The connecting surface 421 is connected to the control circuit board 320, and the sensing surface 422 communicates with the mounting cavity 141 through a sensing channel 410. During rapid, large-volume suction, the pressure inside the mounting cavity 141 decreases, and the sensing surface 422 senses this pressure change and transmits it to the control circuit board 320. The airflow sensor 420 can be integrated with the control circuit board 320 via welding, facilitating easy installation and disassembly, simplifying the assembly process, and improving production efficiency. The battery 310 is arranged along the horizontal X, and the negative pressure channel 120 and the air intake channel 110 are arranged roughly along the horizontal X on both sides of the battery 310. Part of the structure of the air intake channel 110 is formed between the battery 310 and the housing assembly 100. The negative pressure channel 120 and the sensing component 400 are arranged on the side of the battery 310 near the atomizing component 200. The control buttons and the like are arranged between the sensing component 400 and the air intake channel 110, which further makes effective use of the internal space of the housing assembly 100.

[0043] In some embodiments, one end of the sensing channel 410 is spaced apart from the sensing surface 422, and the other end is spaced apart from the cavity wall of the mounting cavity 141. The negative pressure channel 120 is spaced apart from the outer wall of the sealing sleeve 430, so as to avoid the sensing channel 410 or the negative pressure channel 120 from contacting the sensing surface 422 and affecting its sensing sensitivity and accuracy.

[0044] Please see Figure 3 and Figure 4 In some embodiments, the housing assembly 100 includes a housing 130 and a mounting base 140. The mounting base 140 is disposed inside the housing 130. One end of the mounting base 140 is sealed to the control circuit board 320 and forms a mounting cavity 141 with the control circuit board 320. A negative pressure channel 120 is formed on the mounting base 140. A sealing sleeve 430 and an airflow sensor 420 are disposed inside the mounting base. The sensing hole 410 on the sealing sleeve 430 is spaced away from the end face of the airflow sensor 420 and is spaced from the inner wall of the mounting base 140, so that the airflow sensor 420 inside the sealing sleeve 430 can sense the air pressure change inside the mounting base 140.

[0045] Please see Figure 2In some embodiments, the housing assembly 100 is further provided with an airflow channel 150, at least partially covering the outlet end of the negative pressure channel 120, the inlet end of the atomizing channel 210, and the outlet end of the inlet channel 110, so that the negative pressure channel 120, the atomizing channel 210, and the inlet channel 110 are interconnected through the airflow channel 150. The airflow channel 150 serves as an intermediate channel connecting the negative pressure channel 120, the inlet channel 110, and the atomizing channel 210. The airflow channel 150 also allows for the regulation of the air pressure within the mounting cavity 141 to balance with the external environment when the atomizing device is not in operation, and for the convergence of airflow into the atomizing channel 210 when the atomizing device is in operation.

[0046] In some embodiments, the complete coverage of the airflow channel 150 with the outlet of the negative pressure channel 120, the inlet of the atomizing channel 210, and the outlet of the inlet channel 110 can effectively ensure smooth airflow.

[0047] In some embodiments, the airflow channel 150 extends laterally (X) along the housing assembly 100 and longitudinally (Y) along the housing assembly 100. The negative pressure channel 120 and the air intake channel 110 are disposed on the same side of the airflow channel 150, and the atomizing channel 210 is disposed on the other side of the airflow channel 150, causing the airflow to converge from both sides towards the center. Figure 5 The diagram shows airflow from the air intake channel 110 and the negative pressure channel 120 to the atomizing channel 210. This structural design adapts to the existing structural layout of the atomizing component 200 and power supply component of the atomizing device, making full use of the internal space of the atomizing device, helping to reduce structural modifications to the atomizing device, and lowering the cost of modification.

[0048] Please see Figure 6 In some embodiments, the housing assembly 100 is provided with an air inlet 160 and an adjusting member 170. The adjusting member 170 is movable relative to the housing assembly 100 to adjust the size of the air inlet 160, which connects the air intake channel 110 with the outside air. The design of the air inlet 160 allows outside air to enter and carry aerosols for the user's use during inhalation. The size of the air inlet 160 can be adjusted by moving the adjusting member 170, allowing for different air intake volumes and thus adjusting the aerosol content to meet the needs of different users.

[0049] Specifically, the adjusting member 170 is capable of lateral X-movement relative to the housing assembly 100, please refer to [link to relevant documentation]. Figure 7The housing assembly 100 contains a sealing element 180 arranged along the transverse X direction, parallel to the adjusting element 170. The adjusting element 170 has a first adjusting hole 171, and the sealing element 180 has multiple second adjusting holes 181 along the transverse X direction. The multiple second adjusting holes 181 have different sizes, and their sizes can gradually increase or decrease along the transverse X direction. When the second adjusting holes 181 and the first adjusting holes 171 are aligned, they can connect the outside air with the internal air intake channel 110. By moving the adjusting element 170, the first adjusting hole 171 can be aligned with different second adjusting holes 181, thereby adjusting the air intake volume. Of course, there can also be multiple first adjusting holes 171 along the transverse X direction of the housing assembly 100, and only one second adjusting hole 181. When the adjusting element moves, different first adjusting holes 171 are sequentially aligned and connected with the second adjusting hole 181 to adjust the air intake volume.

[0050] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
