Description

Technical Field

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

[0002] Currently, electronic atomizers on the market typically consist of a liquid reservoir, an atomizing component, and an airflow channel. During use, the high-temperature aerosol generated by the heating of the atomizing component flows through the airflow channel, causing a significant increase in the temperature of the airflow channel. Since the airflow channel is usually in direct or indirect contact with the liquid reservoir, its heat is transferred to the liquid reservoir, causing the temperature inside the reservoir to rise.

[0003] The increase in temperature inside the storage chamber can cause two main problems. (1) Decreased viscosity of the atomizing matrix: The increased temperature leads to a decrease in the viscosity of the atomizing matrix (or other liquids) inside the storage chamber, increasing its fluidity and making it easier for it to penetrate into the airflow channel through the liquid guiding material or gaps of the atomizing component, causing leakage. (2) Pressure imbalance inside the storage chamber: The increased temperature may cause the air inside the storage chamber to expand, increasing the pressure, which may cause abnormal leakage of the atomizing matrix under certain conditions. Although there are various leak prevention solutions in the existing technology, such as using more complex sealing structures or high-density liquid guiding materials, their effectiveness is often limited.

[0039] This application discloses an atomizing device, comprising a housing, a mounting base assembly, and an atomizing component. The top wall of the housing has a suction port, and the wall of the suction port extends downwards to form an air outlet. The inner top wall of the housing extends downwards to form an air inlet, which is spaced outside the air outlet. The inner wall of the air inlet and the outer wall of the air outlet cooperate to form a cooling chamber. An air intake channel communicating between the top of the air inlet and the outside atmosphere is formed within the top wall of the housing. The bottom end of the housing is open. The mounting base assembly is sealed and inserted into the bottom end of the housing. An air chamber is formed within the bottom end of the mounting base assembly. The mounting base assembly is sealed and connected to the bottom end of the air outlet. A mounting cavity communicating between the air outlet and the air chamber is formed within the top end of the mounting base assembly. The mounting base assembly is sealed and connected to the bottom end of the air inlet. A communicating channel communicating between the cooling chamber and the air chamber is formed within the top end of the mounting base assembly. The atomizing component is fitted inside the mounting cavity. The atomizing component connects the air outlet and the air chamber. The inner wall of the outer shell, the outer wall of the air inlet, and the mounting base assembly cooperate to form a liquid storage chamber. The liquid storage chamber connects to the mounting cavity, and the atomizing component connects to the liquid storage chamber.

[0040] The atomizing device of this application incorporates a cooling chamber connected to the outside atmosphere. This structure allows for targeted cooling and temperature control of the outlet cylinder. Outside air flows sequentially through the inlet channel, cooling chamber, air chamber, mounting chamber (atomizing components), and outlet cylinder, finally exiting from the suction port. The inlet cylinder, surrounding the outlet cylinder, isolates it from direct contact with the liquid storage chamber. The flowing air within the sleeve-shaped cooling chamber (formed by the inlet and outlet cylinders) cools the outlet cylinder, thus preventing overheating of the outlet cylinder from affecting the liquid storage chamber and effectively solving the leakage problem. Furthermore, the inlet cylinder, outlet cylinder, and outer shell (including the inlet channel and suction port) of the atomizing device of this application are integrally molded, reducing the risk of air and liquid leakage, facilitating manufacturing, and making it suitable for large-scale, automated production of atomizing devices.

[0041] Please see Figures 1 to 6d The following will mainly describe the specific structure of the electronic atomizer.

[0042] The electronic atomizer of this application includes a housing 100, which is in the shape of a chamber. The housing 100 can be in the shape of a round chamber, a square chamber, a polygonal chamber, or an irregularly shaped chamber, etc.

[0043] The top wall of the outer casing 100 has a suction port 110 for the user to inhale the aerosol generated by atomization. The wall of the suction port 110 extends downwards to form an outlet cylinder 120, which is integrally formed with the outer casing 100. The outlet cylinder 120 can be cylindrical (preferably), square, polygonal, or irregularly shaped. The bottom end of the outlet cylinder 120 is open.

[0044] An air inlet 130 extends downward from the top inner wall of the outer casing 100, meaning the air outlet 120 is integrally formed with the outer casing 100, and the air inlet 130 is spaced out from the air outlet 120. The shape of the air inlet 130 can also be cylindrical (preferably), square, polygonal, or irregularly shaped. The bottom end of the air inlet 130 is also open. The inner wall of the air inlet 130 and the outer wall of the air outlet 120 cooperate to form a cooling chamber 140; in other words, the cooling chamber 140 is the gap between the air inlet 130 and the air outlet 120. An air intake channel 150 is provided in the top wall of the outer casing 100, connecting the top of the air inlet 130 to the outside atmosphere. The air intake channel 150 can be straight or curved, and it mainly extends in the horizontal direction.

[0045] In some embodiments, the intake passage 150 is a straight passage that extends horizontally. The top inner wall of the housing 100 extends downward to form the intake passage 150, thereby allowing air to flow smoothly from the intake passage 150 into the cooling chamber 140.

[0046] In some embodiments, the top of the air intake cylinder 130 may be higher than the top of the air intake channel 150, thereby preventing external airflow from directly impacting the air intake cylinder 130 (i.e., the cooling chamber 140), resulting in a gentler airflow and a more uniform and stable air intake volume.

[0047] The air inlet cylinder 130, air outlet cylinder 120 and outer shell 100 of the atomizing device 10 of this application are integrally formed, which is convenient to manufacture, suitable for large-scale and automated production of the atomizing device 10, and is not prone to air leakage.

[0048] The bottom end of the outer casing 100 is open. The atomizing device 10 of this application includes a mounting base assembly 200, which is sealed and inserted into the bottom end of the outer casing 100. An air chamber 240 is formed inside the bottom end of the mounting base assembly 200. The mounting base assembly 200 is sealed and connected to the bottom end of the air outlet cylinder 120. A mounting cavity communicating between the air outlet cylinder 120 and the air chamber 240 is formed inside the mounting base assembly 200 (or inside the top end of the mounting base assembly 200). The bottom end of the air inlet cylinder 130 is sealed and connected to the bottom end of the mounting base assembly 200. A communicating channel communicating between the cooling chamber 140 and the air chamber 240 is formed inside the mounting base assembly 200 (or inside the top end of the mounting base assembly 200).

[0049] In some specific embodiments, the mounting base assembly 200 includes a connecting cylinder 210, a connecting base 220, and a base 230. The connecting cylinder 210 is inserted into the top end of the connecting base 220 and connects the bottom end of the air outlet 120 and the bottom end of the air inlet 130. The base 230 is located below the connecting base 220, and the top surface of the base 230 is connected to the bottom surface of the connecting base 220. A mounting cavity is formed in the connecting cylinder 210 and the connecting base 220, a connecting channel is formed in the connecting cylinder 210 and the connecting base 220, and an air chamber 240 is formed between the connecting base 220 and the base 230.

[0050] In the above embodiments, the connecting cylinder 210 can be made of an elastic material (e.g., plastic, silicone, and / or rubber), while the connecting seat 220 and the base 230 can both be made of a rigid material (e.g., plastic). By utilizing the differentiated combination of soft and hard materials in the connecting cylinder 210, connecting seat 220, and base 230, the mounting assembly 200 can both tightly fit the outer shell 100 and the atomizing component 300 (described in detail below) to ensure a seal, and also firmly connect with the outer shell 100 and the atomizing component 300 to ensure strength, thus achieving a dual functional objective. The outer walls of the connecting seat 220 and the base 230 can each be fitted with a sealing ring (which can be made of materials such as plastic, silicone, and / or rubber), thereby improving the sealing connection between the two and the inner wall of the outer shell 100.

[0051] The connecting cylinder 210 is integrally formed and includes a first sub-cylinder 211, a connecting ring plate 212, and a second sub-cylinder 213 arranged from top to bottom and coaxially connected. The inner diameter of the first sub-cylinder 211 is larger than the inner diameter of the connecting ring plate 212, and the inner diameter of the first sub-cylinder 211 is greater than or equal to the outer diameter of the second sub-cylinder 213. A first channel 214, which runs vertically through the connection between the first sub-cylinder 211 and the connecting ring plate 212, is hollowed out and located outside the second sub-cylinder 213. The bottom outer wall of the air inlet cylinder 130 is connected (which may be an interference fit) to the inner wall of the first sub-cylinder 211, the cooling chamber 140 is connected to the first channel 214, the bottom outer wall of the air outlet cylinder 120 is connected (which may be an interference fit) to the inner wall of the ring plate 212, and the air outlet cylinder 120 is connected to the second sub-cylinder 213. This configuration allows for the isolation of the air intake passage (flowing in from the air intake cylinder 130) and the air outlet passage (flowing out from the air chamber 240) on the connecting cylinder 210.

[0052] The connecting seat 220 is hollowed out to form a second channel 221 that runs vertically through it. The second channel 221 connects the first channel 214 and the air cavity 240. The connecting channel is formed by the first channel 214 and the second channel 221. The connecting seat 220 is hollowed out to form a connecting cavity 222 that runs vertically through it. The connecting cavity 222 connects the second sub-cylinder 213 and the air cavity 240. The mounting cavity is formed by the second sub-cylinder 213 and the connecting cavity 222.

[0053] The top surface of the connecting seat 220 is recessed downwards to form a slot 223 corresponding to the connecting cylinder 210. The connecting cylinder 210 is interference-fitted into the slot 223. The top end of the second channel 221 penetrates the bottom of the slot 223 near the edge, and the top end of the connecting cavity 222 penetrates the bottom of the slot 223 near the center. The above arrangement is adapted to the arrangement of the cooling cavity 140 surrounding the air outlet 120.

[0054] The bottom end of the air inlet cylinder 130 has a notch 131. The bottom surface of the air inlet cylinder 130 is connected to the top surface of the connecting ring plate 212, and the bottom surface of the connecting cylinder 210 is connected to the top surface of the connecting seat 220. The notch 131, the first channel 214, and the second channel 221 are sequentially opposite each other. Based on the above configuration, the contact area of ​​the sequentially connected connecting cylinder 210, connecting seat 220, and base 230 is large, and the connection is relatively tight. While ensuring that all parts of the connecting channel (formed by the first channel 214 and the second channel 221) and the mounting cavity (formed by the second sub-cylinder 213 and the connecting cavity 222) are unobstructed, air leakage and liquid leakage are unlikely to occur.

[0055] There are multiple notches 131 arranged circumferentially along the air intake cylinder 130. The number of notches 131, the number of first channels 214, and the number of second channels 221 are the same, and the multiple notches 131, multiple first channels 214, and multiple second channels 221 are arranged in a one-to-one correspondence. As a result, the atomizing device 10 can intake air from all directions, with a relatively large air intake volume, uniform air intake, and good air intake effect.

[0056] The air intake cylinder 130 has a connecting hole 132 corresponding to the air intake channel 150, and the notch 131 and the connecting hole 132 are located on different vertical lines. Therefore, by staggering the connecting hole 132 and the notch 131, the air flow time in the first channel 214 can be extended, and the air in the air intake cylinder 130 can flow more smoothly into the first channel 214. This not only makes the air intake volume more uniform and stable, but also improves the cooling effect of the cooling chamber 140 on the air outlet cylinder 120.

[0057] The inner wall of the outer casing 100, the outer wall of the air inlet 130, and the mounting base assembly 200 cooperate to form a liquid storage chamber 400. The liquid storage chamber 400 is used to store the atomizing matrix and is connected to the mounting cavity. In other words, the air outlet 120 is located between the air inlet 130 and the liquid storage chamber 400, meaning that the air outlet 120 does not directly contact the liquid storage chamber 400. The heat from the air outlet 120 is cooled by the cooling chamber 140 and then transferred to the liquid storage chamber 400, thereby preventing the air outlet 120 from heating up and affecting the liquid storage chamber 400, effectively solving the problem of leakage in the liquid storage chamber 400.

[0058] In some embodiments, the liquid storage chamber 400 includes a liquid storage area 410 and a liquid guiding area that communicate with each other. The liquid storage area 410 is formed by the connecting seat 220, the inner wall of the outer shell 100, and the outer wall of the air inlet cylinder 130. The capacity of the liquid storage area 410 is greater than the capacity of the liquid guiding area. The liquid storage area 410 is used to store the atomizing matrix. The liquid guiding area is located below the liquid storage area 410. The liquid guiding area is formed by hollowing out the connecting seat 220. The liquid guiding area communicates with the communicating cavity 222. The liquid guiding area is mainly used to guide the atomizing matrix in the liquid storage area 410 to the mounting cavity (as mentioned above, the communicating cavity 222 is part of the mounting cavity).

[0059] The number of liquid guiding zones is the same as the number of second channels 221. The connecting cavity 222 is a cylindrical cavity, and multiple liquid guiding zones are arranged circumferentially in the connecting cavity 222. A second channel 221 is arranged between any two adjacent liquid guiding zones. Thus, the atomizing matrix flows into the connecting cavity 222 from all directions, resulting in a suitable and uniform liquid inlet volume in the mounting cavity. The number of second channels 221 and liquid guiding zones can be two, three, four (preferably), or more, without specific limitation. Understandably, to avoid gas and liquid leakage caused by gas-liquid mixing, the liquid guiding zones and second channels 221 are not connected on the connecting seat 220.

[0060] The inner top wall of the portion of the liquid guiding zone near the connecting cavity 222 curves upward or slopes away from the connecting cavity 222, meaning that the portion of the liquid guiding zone near the connecting cavity 222 forms a cross-sectional shape that is flat at the bottom and convex at the top. This arc-shaped structure makes the top space of the portion of the liquid guiding zone near the connecting cavity 222 gradually rise, which is conducive to the flow of gas (which has a lower density than the atomizing matrix and flows upward) from the upper part of the portion of the liquid guiding zone near the connecting cavity 222, and also facilitates the ventilation of the liquid storage chamber 400 and the atomizing component 300 (detailed later).

[0061] In some embodiments, the liquid guiding zone includes a vertical sub-channel 420 and a horizontal sub-channel 430. The vertical sub-channel 420 extends vertically and is formed by the sidewall of the connecting seat 220 and the inner wall of the outer shell 100. The top end of the vertical sub-channel 420 connects to the liquid storage zone 410. The horizontal sub-channel 430 extends horizontally and its two ends connect to the bottom end of the vertical sub-channel 420 and the connecting cavity 222. In the axial section of the horizontal sub-channel 430, the top inner wall of the horizontal sub-channel 430 (the portion of the liquid guiding zone near the connecting cavity 222) is curved upwards in an arc shape away from the connecting cavity 222. Based on the above configuration, the liquid guiding zone is designed with a bidirectional flow guiding structure of vertical and horizontal for the atomizing matrix, which not only covers a more comprehensive flow guiding direction but also avoids the limitations of unidirectional flow guiding, significantly improving the flow guiding effect.

[0062] The atomizing device 10 of this application includes an atomizing component 300, which is sleeved in a mounting cavity. Since the mounting cavity connects to the air outlet 120, the air chamber 240, and the liquid storage chamber 400, the atomizing component 300 also connects to the air outlet 120, the air chamber 240, and the liquid storage chamber 400. Specifically, the atomizing chamber 310 of the atomizing component 300 connects to the air outlet 120 and the air chamber 240, and the liquid inlet 320 of the atomizing component 300 connects to the liquid storage chamber 400.

[0063] In some specific embodiments, the top end of the atomizing component 300 is connected to the inner wall of the second sub-tube 213, and the remaining part of the atomizing component 300 is connected to the cavity wall of the connecting cavity 222. The atomizing cavity 310 is formed in the middle of the atomizing component 300 and extends vertically. The bottom surface of the atomizing component 300 (i.e., the air inlet end of the atomizing cavity 310) is opposite to the air cavity 240. The atomizing cavity 310 connects the air outlet 120 and the air cavity 240, and the aerosol generated by the atomizing component 300 can be discharged through the air outlet 120. At the same time, the connection between the atomizing component 300 and the mounting base assembly 200 is firm (with an interference fit soft connection to the connecting tube 210, and with a rigid connection to the connecting base 220), and the sealing connection effect is good.

[0064] The atomizing component 300 has a liquid inlet 320 on its outer wall, which is opposite to the liquid storage chamber 400. In some preferred embodiments, the liquid inlet 320 is located within the portion of the atomizing component 300 facing the liquid storage chamber 400, meaning the wall of the liquid inlet 320 does not contact the wall of the connecting cavity 222, thus preventing leakage of the atomizing matrix between the mounting cavity and the atomizing component 300. When the atomizing component 300 is working, it continuously consumes the atomizing matrix. As the atomizing matrix decreases, a negative pressure is generated inside the liquid storage chamber 400. The gas from the atomizing component 300 (which is connected to the outside via the air outlet 120) flows back to the liquid storage chamber 400 from the upper part of the horizontal channel 430, alleviating the negative pressure in the liquid storage chamber 400 and making the flow rate of the atomizing matrix to the atomizing component 300 more stable.

[0065] This application provides an electronic atomizer, which includes an electronic control device and the aforementioned atomizing device 10. The bottom end of the atomizing device 10 is connected to the electronic control device (not shown). The electronic atomizer of this application includes the atomizing device 10, and therefore has all the beneficial effects of the aforementioned atomizing device 10, which will not be described in detail here.

[0066] The bottom wall of the mounting assembly 200 (specifically the base 230) has a vent 231 that connects to the air chamber 240. The internal structure of the electronic control device forms a sensing airway connected to the outside atmosphere. This sensing airway connects to the vent 231. The electronic control device includes an airflow sensor and a control unit. The airflow sensor is located within the sensing airway, with one side connected to the vent 231 and the other side connected to the outside atmosphere. The airflow sensor and the atomizing assembly 300 are electrically connected to the control unit. The control unit responds to the sensing signal from the airflow sensor to control the operation of the atomizing assembly 300. Thus, when the user inhales, a negative pressure is created within the air outlet 120, triggering the airflow sensor. The control unit receives the trigger signal from the airflow sensor and controls the atomizing assembly 300 to atomize the atomizing medium. Triggering the atomizing assembly 300's operation through user inhalation avoids the atomizing assembly 300 operating when not in use, reducing safety hazards associated with the electronic atomizer and saving energy for the electronic control device.
