With the pursuit of smoking automation by smokers and the continuous advancements in tobacco vaporization technologies, the demand for vaporization devices among consumers has gradually increased. However, existing vaporization devices require smokers to manually control heating, resulting in cumbersome workflows for users. Manual operation is not sufficiently convenient for smokers and wastes considerable time. Most vaporization devices cannot be used or turned off immediately, leading to waste of e-liquid. In the related art, the vaporization device is equipped with an airflow sensor and other detection devices to monitor the user's operations. However, the positional relationship of the airflow sensor in the current technology may lead to uncertainty in the sensitivity and operational safety of the airflow sensor.

According to an embodiment of the present application, a vaporization device 1 is provided, referring to FIG. 1 and FIG. 2. The vaporization device 1 includes a shell 10, a bracket 20, a circuit board 30, an airflow sensor 40, and a sealing element 50. The vaporization device 1 can utilize a device that disperses liquid to generate tiny droplets, and the volume of the vaporized droplets decreases, making them easily pass through gaps. To increase the utilization rate of tiny droplets and reduce the loss of tiny droplets, the shell 10 forms a cavity 11. The circuit board 30 is assembled in the shell 10, and the airflow sensor 40 and sealing element 50 are arranged within the cavity 11. Preferably, during operation of the vaporization device 1, processes such as heating may be involved, so as to avoid heat dissipation from the shell 10, preventing loss of heat. Similarly, this avoids generating high temperatures on the surface of the shell 10, which presents risks. The shell 10 can utilize thermal insulation materials. For example, the shell 10 can use ceramic materials, which not only resist high temperatures but also have strong corrosion resistance and durability. The circuit board 30 generally has a sheet structure and needs to be installed and fixed in the cavity 11, with the shell 10 having installation holes 12 for positioning and installing the circuit board 30 and other parts.

According to some embodiments, referring to FIG. 3, the circuit board 30 includes a first surface 31 and a second surface 32 opposite to the first surface 31, with the second surface 32 facing the installation hole 12, and the second surface 32 and installation hole 12 having a relative positional relationship. The installation hole 12 can be used for positioning the second surface 32, thereby determining the positional relationship between the circuit board 30 and the shell 10. Moreover, to avoid obstructing air circulation within the cavity 11, the circuit board 30 also includes a first air hole 33, allowing air passing through the circuit board 30 to flow smoothly. The bracket 20 is arranged within the cavity 11, and the circuit board 30 is fixed to the bracket 20. In the cavity 11, the bracket 20 keeps the circuit board 30 in position, preventing it from moving easily. The bracket 20 can be made of flexible materials. For example, the bracket 20 can use rubber or similar materials, reducing damage to the circuit board 30 caused by jolts or vibrations.

The circuit board 30 can include one or more (only one is shown in the figure) coupled processors 301 and memory 302. Referring to FIG. 4 and take the circuit board 30 as an example.

The processor 301 may include one or more processing cores. The processor 301 connects all parts within the vaporizing device 1 via various interfaces and lines. By running or executing instructions, programs, code collections, or instruction sets stored in the memory 302, as well as retrieving data stored in the memory 302, it performs various functions and processes data. In some embodiments, the processor 301 can employ at least one hardware form among Digital Signal Processing (DSP), Field-Programmable Gate Array (FPGA), or Programmable Logic Array (PLA).

Memory 302 can include Random Access Memory (RAM) and Read-Only Memory (ROM). Memory 302 can be used to store instructions, programs, codes, code collections, or instruction sets.

In this embodiment, referring to FIG. 2, if the vaporization device 1 experiences vibrations or impacts, components can easily fall off from the circuit board 30. The sealing element 50 fills the space between the bracket 20 and the circuit board 30. During operation of the vaporization device 1, tiny droplets will also occur within the cavity 11. The sealing element 50 can prevent tiny droplets from escaping the vaporization device 1 and can also divide different parts of the cavity 11. The sealing element 50 provides cushioning. It can reduce damage from external vibrations to the circuit board 30 and can fill the gap between the shell 10 and the circuit board 30, reducing the gap size between the shell 10 and the circuit board 30 to prevent the gap from becoming excessively large, which could allow tiny droplets generated during vaporization to penetrate between the shell 10 and the circuit board 30, causing loss and ensuring the smooth operation of the vaporization device 1.

In this embodiment, conventional vaporization devices require manual operation by users to initiate operation, but this manual process is cumbersome and leads to slower response times. The airflow sensor 40 is electrically connected to the second surface 32 and can include a differential capacitive sensor. When a user inhales when using the vaporization device 1, changes in the airflow speed generated by inhalation affect the air pressure within the cavity 11. The airflow sensor 40 experiences pressure changes at both ends, and the airflow speed influences the capacitance values across the airflow sensor 40, resulting in a capacitance difference. The airflow sensor 40 determines trigger signals based on the capacitance difference and can adjust sensitivity according to a preset capacitance threshold. The airflow sensor 40 is electrically connected to the second area 35, transmitting signals to the circuit board 30. To reduce unnecessary misfires and avoid influences from external airflow on the airflow sensor 40, the circuit board 30 is set with a threshold to determine if the capacitance difference exceeds the threshold. When the capacitance difference exceeds the threshold, the circuit board 30 controls the vaporization device 1 to heat, generating tiny droplets from the vaporized e-liquid, which emits a cigarette aroma, while controlling the corresponding display circuit to realize necessary display functions. When the capacitance difference does not exceed the threshold, the circuit board 30 performs no other operations and remains in standby mode.

According to some embodiments, the working principle of the airflow sensor 40 is that the airflow speed affects the capacitance values at both ends of the airflow sensor 40, resulting in a capacitance difference. The airflow sensor 40 uses the capacitance difference to determine trigger signals. The airflow sensor 40 detects the airflow speed without the influence of airflow at one end away from the second air passage 102, using this reference to generate a capacitance difference. Due to the positional relationship between the airflow sensor 40 and the second surface 32, the circuit board 30 is provided with a second air hole 36, where the second air hole 36 penetrates through the first surface 31 and corresponds to the airflow sensor 40. The end of the airflow sensor 40 near the second air hole 36 can detect gas parameters without the influence of airflow, while the other end can acquire gas parameters from within the second air passage 102, and the capacitance at both ends varies according to the acquired gas parameters. The airflow sensor 40 can obtain the capacitance difference at both ends and convert the capacitance difference into parameter values such as air pressure differences.

In this embodiment, to ensure a smooth inhalation rate for the user, the diameter of the air passage is not set too small. The airflow sensor 40 is used to detect changes in air intake rates, and the diameter parameters of the air passage will affect the intake rate of air into the cavity 11, thereby affecting the sensitivity of the airflow sensor 40. The shell 10 defines a first air passage 101 and a second air passage 102, the first air passage 101 communicating with the installation hole 12 and the first air hole 33, the second air passage 102 communicating with the first air passage 101 and being positioned on one side of the first air passage 101, with the airflow sensor 40 arranged at one end of the second air passage 102 away from the first air passage 101. The shell 10 separates the first air passage 101 and the second air passage 102, with both passages connected to each other. When the user inhales, the airflow speed in the first air passage 101 increases. According to Bernoulli's principle, under certain conditions, a high-speed airflow in the first air passage 101 results in a lower corresponding air pressure. The reduction in pressure in the first air passage 101 causes gas from the second air passage 102 to flow into the first air passage 101, while the airflow speed and air pressure in the second air passage 102 change accordingly, being detected by the airflow sensor 40 in the second air passage 102. According to some embodiments, a larger diameter can be set for the first air passage 101, for example, the first air passage 101 can be set to 5 mm to ensure a smooth inhalation rate for the user; while the second air passage 102 can be set to a smaller diameter, for example, the second air passage 102 can be set to 2 mm to accommodate the airflow sensor 40. The airflow sensor 40 can detect changes in airflow more clearly with the smaller diameter of the second air passage 102 under the same intake volume.

In this embodiment, e-liquid may overflow from the oil chamber 62 in the first air passage 101, as the second air passage 102 communicates with the first air passage 101, resulting in e-liquid potentially overflowing from the first air passage 101 into the second air passage 102. Due to the small size of the second air passage 102, e-liquid may clog the second air passage 102, affecting the normal operation of the airflow sensor 40 in the second air passage 102. The second air passage 102 is formed with multiple bent portions 90, which can increase the length of the second air passage 102. The position of the airflow sensor 40 can also increase, with specific parameters adjustable according to implementation requirements, without limitation in this embodiment. Moreover, the multiple bent portions 90 can reduce airflow in the second air passage 102, preventing the airflow speed in the first air passage 101 from affecting the airflow speed in the second air passage 102. The bent portions 90 can obstruct the airflow coming from the first air passage 101, preventing potential damage to the airflow sensor 40.

Specifically, referring to FIG. 6, the second air passage 102 includes a first gas segment 1021, a second gas segment 1022, and a third gas segment 1023, where the first gas segment 1021 bends towards the first air passage 101 to form a first bend 901, the third gas segment 1023 bends towards the first air passage 101 to form a second bend 902, and both ends of the second gas segment 1022 connect the first bend 901 and an end of the third air segment 1023 away from the second bend 902. The second air passage 102 can have a larger size in a confined space, further increasing the length of the second air passage 102 and increasing the distance between the airflow sensor 40 and the first air passage 101. When e-liquid overflows from the oil chamber 62 into the first air passage 101, the second air passage 102 can provide enough space to buffer the overflowing e-liquid, preventing damage to the airflow sensor 40. Protecting the proper function of the airflow sensor 40 and preventing the influence of the first air passage 101 can ensure smooth operation of the vaporization device 1.

In this embodiment, referring to FIG. 2 and FIG. 5, the circuit board 30 includes a first area 34 and a second area 35 connected together. The first air hole 33 is arranged in the first area 34. The vaporization device 1 further includes a power supply component 60, which includes a power source 61 and an oil chamber 62. The power source 61 and the oil chamber 62 are larger, heavier components in the vaporization device 1, and can easily displace and collide with each other. The power source 61 and the oil chamber 62 are fixedly assembled, and the fixed assembly minimizes the risk of collisions that could lead to leaks from the oil chamber 62. To reduce assembly procedures and ensure assembly precision and speed, the power source 61 corresponds to the second area 35 and is electrically connected to the circuit board 30, supplying power to the circuit board 30 to ensure its normal operation, while the airflow sensor 40 is arranged in the second area 35, and the circuit board 30 can supply power to the airflow sensor 40, providing the necessary power for its operation. The oil chamber 62 corresponds to the first area 34 and is provided with heating wire 621 inside, which is used to heat e-liquid or other liquid substances. The heating wire 621 utilizes the property of generating heat through electricity, thus the heating wire 621 connects with the power supply component 60. The oil chamber 62 needs to store heated e-liquid, and a sealed oil chamber 62 can easily create negative pressure. The negative pressure can prevent tiny droplets generated within oil chamber 62 from flowing out smoothly from the vaporization device 1, while the first air passage 101 communicates with the oil chamber 62 allowing air to pass through the first air passage, thus enabling tiny droplets to flow out smoothly from the vaporization device 1.

According to some embodiments, the heating wire 621 includes pins extending toward the circuit board 30 for connection to the power supply component 60. To ensure the safety of the connections and protect the normal operation of the heating wire 621, a resistance wire is provided within the vaporization device 1, connecting the power source 61 and the heating wire 621. The resistance wire conducts with the power source 61, providing current to both ends of the resistance wire. The resistance wire connects to the heating wire 621, causing the heating wire 621 to generate heat. E-liquid begins to heat up via the heating wire 621, turning into tiny droplets for the user to inhale.

In this embodiment, to ensure that smoke can be smoothly expelled from the vaporization device 1, liquids form tiny droplets within air passages. The user inhales through the vaporization device 1, generating a driving force that causes the tiny droplets to rise smoothly along the airflow passage and be inhaled by the user. Under the influence of this driving force, outside moisture or other gases may enter the first air passage 101 and the second air passage 102. Moisture entering the oil chamber 62 can dilute the e-liquid, and the heated steam together with the vaporized tiny droplets is inhaled by the user. The steam may cause burns to the user's oral cavity, and the mixture can create unpleasant tasting effects. The vaporization device 1 further includes oil-absorbent cotton 80, which is arranged on the bracket 20 and located on one side of the second surface 32 of the circuit board 30 and positioned between the first air hole 33 and the first air passage 101. Moisture in the first air passage 101 and the second air passage 102 is filtered before passing through the second surface 32, allowing the oil-absorbent cotton 80 to absorb incoming moisture, reducing the occurrence of unpleasant tastes caused by moisture. Additionally, e-liquid may overflow from the oil chamber 62. When the e-liquid passes through the second surface 32, it is absorbed by the oil-absorbent cotton 80, effectively preventing e-liquid from leaking from the vaporization device 1. Preferably, external moisture enters the cavity 11, and the moisture flows along the first air passage 101 to the circuit board 30 or sequentially along the second air passage 102 and the first air passage 101 to the circuit board 30. The moisture can corrode the circuit board 30, leading to its improper operation. The junction of the second air passage 102 and the first air passage 101 is located on the side of the oil-absorbent cotton 80 away from the circuit board 30. The moisture in the first air passage 101 and the second air passage 102 is filtered before passing through the second surface 32, allowing the oil-absorbent cotton 80 to absorb the incoming moisture.

In this embodiment, to ensure that smoke can be smoothly expelled from the vaporization device 1, liquids in the cavity 11 form tiny droplets. The user inhales the vaporization device 1, generating a driving force for the airflow passage. Under the influence of this driving force, the tiny droplets rise slowly along the airflow passage and are smoothly inhaled by the user. Under the influence of the driving force, external moisture or other gases may enter the first air passage 101 and the second air passage 102. Moisture entering the oil chamber 62 can dilute the e-liquid, and the heated steam, along with the vaporized tiny droplets, is inhaled by the user. The steam may cause burns to the user's oral cavity, and the mixture can lead to unpleasant taste effects. The junction of the second air passage 102 and the first air passage 101 is located on the side of the oil-absorbent cotton 80 away from the circuit board 30. The moisture in the first air passage 101 and the second air passage 102 is filtered before passing through the second surface 32, allowing the oil-absorbent cotton 80 to absorb the incoming moisture and reduce the occurrence of unpleasant taste effects caused by moisture. Moreover, e-liquid may overflow from the oil chamber 62. As the e-liquid passes through the second surface 32, it is absorbed by the oil-absorbent cotton 80, effectively preventing e-liquid from leaking from the vaporization device 1.

In this embodiment, referring to FIG. 2 and FIG. 7, according to consumers' usage habits, there are variances in how users utilize the vaporization device 1, including differences in usage rates and single-use vaporization volumes. To change the vaporization volume for the user, the vaporization device 1 also includes an airflow adjustment device 63, which is slidably arranged on the bracket 20 and located at the installation hole 12. The airflow adjustment device 63 is used to adjust the vaporization volume during its sliding process. The sliding arrangement of the airflow adjustment device 63 can change the size of the air intake passage of the vaporizer, thereby altering the air intake rate. The air intake rate affects the rate of tiny droplet generation, allowing users to adjust the vaporization rate to avoid excessive vaporization leading to waste and to prevent the vaporization rate from being too slow, which could result in a poor user experience when the vaporization rate cannot keep up with the user's intake. According to some embodiments, the sealing element 50 further includes a plurality of third air holes 51, the third air holes 51 communicating with the first air hole 33. The airflow adjustment device 63 can slide to change the number of third air holes 51 connected, thereby adjusting the intake rate through the third air holes 51 and modifying the vaporization rate, allowing the vaporization rate to be adjusted reasonably and reducing waste. It can also prevent clogging of the third air holes 51, ensuring that the vaporization device 1 operates normally. For example, in the vaporization device 1, the airflow adjustment device 63 is provided with three third air holes 51, and currently the airflow adjustment device 63 is blocking one of the third air holes 51. When the user uses the vaporization device 1 and finds that the inhalation airflow speed is low, they can adjust the airflow adjustment device 63 to completely unblock all three third air holes 51. Conversely, when the user finds that the inhalation airflow speed is high, they can adjust the airflow adjustment device 63 to block two of the third air holes 51.

In another embodiment, the sealing element 50 is provided with a plurality of third air holes 51, which are distributed along the sliding direction of the airflow adjustment device 63. The diameters of the plurality of third air holes 51 decrease or increase sequentially. The third air holes 51 can be air holes on the bracket 20. The sliding airflow adjustment device 63 can change the connected third air hole 51 corresponding to the air holes. The airflow adjustment device 63 can slide to change the connection to a specific third air hole 51, thereby altering the air intake rate through the third air hole 51 according to the different diameters of the connected third air hole 51, thus adjusting the vaporization rate.

In this embodiment, when the user adjusts the airflow speed of the vaporization device 1, it is necessary to operate the airflow adjustment device 63. However, during the adjustment, users may find it difficult to accurately slide the airflow adjustment device 63 to the correct position due to limited space. The airflow adjustment device 63 includes a fixing plate 631 and a protruding portion 632. The protruding portion 632 is arranged on the surface of the fixing plate 631, the fixing plate 631 is slidably assembled on the bracket 20, the protruding portion 632 extends from the installation hole 12 and is used to drive the fixing plate 631 to move by external force, so that the fixing plate 631 during the sliding process selectively closes the plurality of third air holes 51 or shields at least one of the plurality of third air holes 51. Users can push the protruding portion 632 to drive the fixing plate 631 to the appropriate position. This arrangement facilitates user adjustment of the airflow adjustment device 63 and avoids scenarios where the small size of the third air holes 51 or excessive proximity of the airflow adjustment device 63 to the sealing element 50 obstructs the sliding of the airflow adjustment device 63.

Specifically, to ensure that the airflow adjustment device 63 can slide smoothly while avoiding foreign matter from entering the space between the airflow adjustment device 63 and the bracket 20, which could obstruct disassembly for cleaning, the shell 10 includes a bottom plate 13, the installation hole 12 being arranged on the bottom plate 13. The surface of the bracket 20 facing the bottom plate is provided with a first locking position 633 and a second locking position 634, with the first locking position 633 and the second locking position 634 arranged at intervals. The first locking position 633 and the second locking position 634 form a gap between them and the surface of the bracket 20 facing the bottom plate. The airflow adjustment device 63 is slidably arranged within this gap. The adjustment device 63 can slide to guarantee the adjustment of the intake rate through the third air holes 51, and the arrangement of the first locking position 633 and the second locking position 634 allows for disassembly of the adjustment device 63. In one embodiment, if foreign matter enters one of the third air holes 51, the airflow adjustment device 63 can be disassembled using the first locking position 633 and the second locking position 634 for cleaning. After cleaning, the airflow adjustment device 63 can be reassembled within the gap between the first locking position 633 and the second locking position 634, allowing the airflow adjustment device 63 to adjust the intake rate through the third air holes 51.

In one embodiment, the airflow adjustment device 63 positioned in the gap may be interfered with by the first locking position 633 and the second locking position 634. The gap size parameter may be small, making it inconvenient for the user to adjust the airflow adjustment device 63. The protruding portion 632 extends from the space between the first locking position 633 and the second locking position 634 and protrudes through the installation hole 12. This design reduces inconvenience caused by the small gap size when the user operates the airflow adjustment device 63. Preferably, the protruding portion 632 is arranged with a texture on the end away from the sealing element 50 to increase friction, allowing the user to push the airflow adjustment device 63 with less force.

The vaporization device 1 provided by the embodiment of the present application, by separating the first air passage 101 and the second air passage 102 in the shell 10, protects the airflow sensor 40 in the second air passage 102 from damage due to high airflow speeds while allowing precise detection of changes in low airflow speeds. Protecting the proper function of the airflow sensor 40 and improving the detection accuracy can enhance the user experience and increase the lifespan of the vaporization device 1.

The foregoing embodiments are intended to illustrate the technical solutions of this application and are not intended to limit it. Although the application has been described in detail with reference to the aforementioned embodiments, those of ordinary skill in the art should understand that they may still make modifications to the technical solutions described in the above embodiments or equivalently replace some technical features. Such modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions in the embodiments of this application and should all be included within the scope of protection of this application.
