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

[0002] To reduce atomizer leakage, a ventilation channel is typically included in the atomizer to connect the liquid reservoir to the outside atmosphere. However, in practical applications, when the air pressure inside the liquid reservoir changes abruptly, some atomizing medium can still leak through the ventilation channel, potentially clogging the air inlet. Utility Model Content

[0003] The purpose of this application is to provide an atomizer and an electronic atomizing device to solve the technical problem of leakage in the air exchange channel in the prior art.

[0004] To achieve the above objectives, the technical solution adopted in this application is as follows: An atomizer is provided, comprising a liquid storage chamber, a ventilation channel, and a receiving chamber. The liquid storage chamber is used to store an atomizing medium. One end of the ventilation channel is connected to the liquid storage chamber, and the other end of the ventilation channel is connected to the receiving chamber. The receiving chamber is connected to the external atmosphere and is used to receive and store the atomizing medium leaking from the ventilation channel. The atomizer further includes a heating element, which is in fluid communication with the liquid storage chamber and the receiving chamber is in fluid communication with the heating element.

[0005] In some embodiments, the ventilation channel has a first ventilation threshold, the heating element has a second ventilation threshold, and the first ventilation threshold is greater than the second ventilation threshold.

[0006] In some embodiments, the atomizer has a liquid guide port communicating with the receiving cavity, the liquid guide port having a liquid guide end face away from the receiving cavity, and a circumference of the liquid guide end face being attached to the atomizing surface of the heating element.

[0007] In some embodiments, the atomizer further includes an air passage and an atomizing chamber communicating with the outside atmosphere, the atomizing surface of the heating element communicating with the atomizing chamber; a first end of the air passage communicating with the receiving cavity, a second end of the air passage communicating with the atomizing cavity, and the first end of the air passage being higher than the bottom wall of the receiving cavity.

[0008] In some embodiments, a blocking structure is formed at the port where the receiving cavity communicates with the air passage. The blocking structure is used to block the atomizing medium in the receiving cavity from flowing to the air passage, while allowing the airflow in the air passage to enter the receiving cavity.

[0009] In some embodiments, the atomizer further includes an atomizing seat, the heating element has a liquid guiding channel communicating with the liquid storage chamber; the top and bottom ends of the heating element are respectively installed on the atomizing seat, and the portion of the heating element located between the top and bottom ends together with the atomizing seat forms an atomizing chamber; the receiving cavity is communicating with the top and / or bottom ends of the heating element.

[0010] In some embodiments, the atomizer includes a main housing and an atomizing seat. The main housing has the liquid storage chamber, and the atomizing seat is installed inside the main housing and covers the bottom end of the liquid storage chamber. The ventilation channel is formed in the atomizing seat, and the receiving cavity is formed on the outer peripheral surface of the atomizing seat.

[0011] In some embodiments, the atomizer includes a main housing and an atomizing seat, the atomizing seat being installed in the main housing, the ventilation channel being formed in the main housing, and the atomizing seat and the main housing together enclosing the receiving cavity.

[0012] In some embodiments, the atomizer further includes a pressure-splitting chamber disposed between the liquid reservoir and the heating element to connect the liquid reservoir and the heating element, wherein the volume of the pressure-splitting chamber is smaller than the volume of the liquid reservoir.

[0013] On the other hand, this application also provides an electronic atomizing device, including a battery structure and the aforementioned atomizer, wherein the battery structure is electrically connected to the atomizer, and the atomizer is used to store an atomizing medium and atomize the atomizing medium to generate an aerosol.

[0014] The beneficial effects of the atomizer provided in this application are as follows: Through the arrangement of the ventilation channel and the receiving cavity, the ventilation channel is connected to the liquid storage cavity and also connected to the external atmosphere through the receiving cavity, enabling the ventilation channel to have a ventilation function. Simultaneously, since the receiving cavity can receive and store atomized media leaking from the ventilation channel, leakage of the atomized media can be reduced or even avoided, preventing the risk of leaked atomized media clogging the air inlet. Furthermore, by fluidly connecting the receiving cavity to the heating element, the atomized media in the receiving cavity can be guided to the heating element, which atomizes the atomized media to generate an aerosol. This improves the utilization rate of the atomized media and avoids leakage due to the accumulation of atomized media in the receiving cavity. Additionally, the heating element heats the atomized media in the receiving cavity and the airflow, thereby improving the ventilation efficiency of the ventilation channel.

[0033] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0036] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0037] As mentioned in the background section, atomizers are prone to leakage and blockage of the air intake port when in use or under sudden changes in internal pressure.

[0038] To address the aforementioned issues, this application provides an atomizer 1 and an electronic atomizing device. By providing a receiving cavity 103 that connects the ventilation channel 102 to the external atmosphere, the receiving cavity 103 receives and stores the atomizing medium leaking from the ventilation channel 102, thereby alleviating or even preventing the atomizing medium leaking from the ventilation channel 102 from clogging the air inlet.

[0039] First, please refer to Figure 1 The electronic atomizing device provided in the embodiments of this application will now be described. The electronic atomizing device includes an atomizer 1 and a battery structure 2. The battery structure 2 is electrically connected to the atomizer 1 and is used to supply power to the atomizer 1. The atomizer 1 stores an atomizing medium inside. When the atomizer 1 is powered on, it can atomize the atomizing medium stored inside to generate an aerosol.

[0040] Please see Figures 1 to 3 The atomizer 1 provided in the embodiments of this application will now be described.

[0041] The atomizer 1 has a liquid storage chamber 101, an air exchange channel 102, and a receiving chamber 103. The liquid storage chamber 101 is used to store the atomizing medium. One end of the air exchange channel 102 is connected to the liquid storage chamber 101, and the other end of the air exchange channel 102 is connected to the receiving chamber 103. The receiving chamber 103 is connected to the outside atmosphere and is used to receive and store the atomizing medium leaking from the air exchange channel 102. The atomizer 1 also includes a heating element 300, which is in fluid communication with the liquid storage chamber 101 and the receiving chamber 103 is in fluid communication with the heating element 300.

[0042] The cross-sectional area and extension length of the ventilation channel 102 can be set according to the actual ventilation needs, so that the liquid storage chamber 101 can be ventilated through the ventilation channel 102 during use or in the event of a sudden change in air pressure.

[0043] In addition, the receiving cavity 103 is mainly used to store the atomizing medium leaking from the ventilation channel 102. The volume of the receiving cavity 103 can be set according to the actual containing requirements and the structural limitations of the atomizer 1, in order to reduce or even avoid the leakage of the atomizing medium from the receiving cavity 103.

[0044] It should be noted that the fluid communication between the receiving cavity 103 and the heating element 300 means that the atomizing medium in the receiving cavity 103 can be drawn into the heating element 300, so that the heating element 300 can atomize the atomizing medium to generate an aerosol.

[0045] During use, the atomizing medium in the storage chamber 101 enters the heating element 300 through the liquid inlet surface and is atomized by the heating element 300. When the temperature and pressure of the storage chamber 101 increase, the atomizing medium in the storage chamber 101 leaks into the receiving chamber 103 through the ventilation channel 102, and some of the atomizing medium in the receiving chamber 103 can be absorbed and atomized by the heating element 300. When the temperature and pressure of the storage chamber 101 decrease, the outside atmosphere enters the storage chamber 101 through the receiving chamber 103 and the ventilation channel 102, and at the same time, some of the atomizing medium in the receiving chamber 103 can be drawn back into the storage chamber 101 for reuse.

[0046] In this embodiment, the atomizer 1, through the arrangement of the ventilation channel 102 and the receiving cavity 103, connects the ventilation channel 102 to the liquid storage cavity 101 and connects the ventilation channel 102 to the external atmosphere through the receiving cavity 103, thus enabling the ventilation channel 102 to have a ventilation function. Simultaneously, since the receiving cavity 103 can receive and store atomized medium leaking from the ventilation channel 102, leakage of the atomized medium can be reduced or even avoided, preventing the risk of leaked atomized medium clogging the air inlet. Furthermore, by fluidly connecting the receiving cavity 103 to the heating element 300, the atomized medium in the receiving cavity 103 can be guided to the heating element 300, allowing the heating element 300 to atomize the atomized medium to generate an aerosol. This improves the utilization rate of the atomized medium and avoids leakage due to the accumulation of atomized medium in the receiving cavity 103. Additionally, the heating element 300 can heat the atomized medium and the airflow in the receiving cavity 103, thereby improving the ventilation efficiency of the ventilation channel 102.

[0047] In some embodiments, the ventilation channel 102 has a first ventilation threshold, and the heating element 300 has a second ventilation threshold. The first ventilation threshold of the ventilation channel 102 is greater than the second ventilation threshold of the heating element 300.

[0048] It should be noted that the ventilation channel 102 has a first ventilation threshold, meaning that when the negative pressure in the liquid storage chamber 101 reaches the first ventilation threshold, the liquid storage chamber 101 can be ventilated through the ventilation channel 102. The heating element 300 has a second ventilation threshold, meaning that when the negative pressure in the liquid storage chamber 101 reaches the second ventilation threshold, the liquid storage chamber 101 can be ventilated through the heating element 300. The first ventilation threshold is greater than the second ventilation threshold. For example, if the first ventilation threshold is -600 Pa and the second ventilation threshold is -1000 Pa, then when the pressure in the liquid storage chamber 101 decreases, the negative pressure in the liquid storage chamber 101 will first reach the first ventilation threshold, causing the liquid storage chamber 101 to be ventilated through the ventilation channel 102 first. This allows the pressure in the liquid storage chamber 101 to gradually reach equilibrium with the external atmosphere, thereby reducing the possibility of leakage of the atomized medium at the heating element 300 due to ventilation. Specifically, during the temperature rise process, the atomized medium in the liquid storage chamber 101 leaks out preferentially through the ventilation channel 102 to balance the pressure in the liquid storage chamber 101; during the cooling process, the process of replenishing gas from the atmosphere and returning it to the liquid storage chamber 101 can draw some of the atomized medium back into the liquid storage chamber 101 through the ventilation channel 102 for continued use.

[0049] Generally, the cross-sectional area of ​​the ventilation channel 102 is set according to the first ventilation threshold of the heating element 300 and the viscosity of the atomizing medium. The first ventilation threshold of the heating element 300 is generally in the range of -300Pa to (-3000Pa), and the viscosity of the atomizing medium is generally in the range of 0-500W.

[0050] In some embodiments, the cross-sectional area of ​​the ventilation channel 102 ranges from 0.2 mm. 2 -15mm 2 For example, the cross-sectional area of ​​the ventilation channel 102 can be 0.2 mm². 2 0.4mm 2 0.6mm 2 0.8mm 2 1mm 2 2mm 2 3mm 2 4mm 2 5mm 2 6mm 2 7mm 2 8mm 2 9mm 2 10mm 2 11mm 2 12mm 2 13mm², 14mm 2 Or 15mm 2Etc. Among them, the cross-sectional area of ​​the ventilation channel 102 cannot be too small. If it is too small, the first ventilation threshold of the ventilation channel 102 will be smaller, which means that the heating element 300 will easily ventilate before the ventilation channel 102. At the same time, it will also make the processing of the ventilation channel 102 more difficult. The cross-sectional area of ​​the ventilation channel 102 cannot be too large either. If it is too large, the ventilation channel 102 will be easier to start, resulting in frequent ventilation of the liquid storage chamber 101, which will lead to leakage.

[0051] Optionally, the cross-section of the ventilation channel 102 can be circular, elliptical, or square, which reduces the amount of atomized medium remaining on the inner wall of the ventilation channel 102 while achieving the ventilation effect. It is understood that in other embodiments of this application, the cross-section of the ventilation channel 102 is not limited and can be a closed shape formed by straight lines and / or curves. For example, it can be a closed shape formed by connecting multiple straight lines end-to-end, or it can be a closed shape formed by connecting multiple curves end-to-end, or it can be a closed shape formed by connecting at least one straight line and at least one curve end-to-end.

[0052] In some embodiments, please refer to Figure 4 and Figure 5 The atomizer 1 has a liquid guide port 1041 communicating with the receiving cavity 103. The liquid guide port 1041 has a liquid guide end face away from the receiving cavity 103. The periphery of the liquid guide end face is attached to the atomizing surface 312 of the heating element 300. The above arrangement allows the atomizing medium in the receiving cavity 103 to be guided to the heating element 300 through the liquid guide port 1041 without leakage between the liquid guide port 1041 and the heating element 300. This allows the portion of the atomizing medium leaking from the ventilation channel 102 to be heated and atomized by the heating element 300 to generate an aerosol, thereby improving the utilization rate of the atomizing medium.

[0053] In some embodiments, please refer to Figure 4 and Figure 5 The atomizer 1 also has a connecting channel 104, one end of which is connected to the receiving cavity 103, and a liquid guide port 1041 is formed at the end of the connecting channel 104 opposite to the receiving cavity 103. The connecting channel 104 facilitates the guidance of the atomizing medium in the receiving cavity 103 to the heating element 300. For example, due to structural design requirements, the receiving cavity 103 is positioned relatively far from the heating element 300; in this case, the connecting channel 104 can guide the atomizing medium in the receiving cavity 103, which is farther from the heating element 300, to the heating element 300. It is understood that in other embodiments of this application, when the distance between the receiving cavity 103 and the heating element 300 is close, the receiving cavity 103 can be directly connected to the heating element 300 without the need for the connecting channel 104.

[0054] In some embodiments, please refer to Figure 6The atomizer 1 also has an air passage 105. The first end of the air passage 105 is connected to the receiving cavity 103, and the second end of the air passage 105 is connected to the outside atmosphere. The first end of the air passage 105 is higher than the bottom wall of the receiving cavity 103. The air passage 105 connects the receiving cavity 103 to the outside atmosphere, enabling the ventilation channel 102 to have a ventilation function. At the same time, by setting the first end of the air passage 105 higher than the bottom wall of the receiving cavity 103, the outside atmosphere can smoothly enter the receiving cavity 103, and the atomizing medium in the receiving cavity 103 will not leak out through the air passage 105.

[0055] Optionally, the first end of the airway 105 is higher than the bottom wall of the receiving cavity 103 by a first distance. The value of the first distance can be set according to actual needs. If the cross-sectional area of ​​the receiving cavity 103 is small, the first distance can be set larger; if the cross-sectional area of ​​the receiving cavity 103 is large, the first distance can be set smaller; if the capacity of the atomizer 1 is small, the first distance can also be set smaller.

[0056] In some embodiments, please refer to Figure 4 and Figure 6 The atomizer 1 also includes an air passage 105 and an atomizing chamber 107 communicating with the external atmosphere. The atomizing surface 312 of the heating element 300 is connected to the atomizing chamber 107. The first end of the air passage 105 is connected to the receiving cavity 103, and the second end of the air passage 105 is connected to the atomizing chamber 107. The first end of the air passage 105 is higher than the bottom wall of the receiving cavity 103. By connecting the air passage 105 to the atomizing chamber 107 and introducing external airflow through the atomizing chamber 107, it is possible to avoid setting air holes on the surface of the atomizer 1, thus avoiding affecting the appearance of the atomizer 1 and reducing the processing difficulty of the air holes. It is understood that in other embodiments of this application, the air passage 105 may also be directly connected to the external atmosphere, which is not the only limitation here.

[0057] In this application, the heating element 300 can be either a cylindrical heating element 300 or a block heating element 300. The following description uses a cylindrical heating element 300 as an example.

[0058] Please see Figure 3 and Figure 4The heating element 300 has a liquid guiding channel 311 communicating with the liquid storage chamber 101. The inner peripheral surface of the heating element 300 is the liquid inlet surface, and the outer peripheral surface of the heating element 300 is the atomizing surface 312. The top and bottom ends of the heating element 300 are respectively installed on the atomizing base 200. The portion of the heating element 300 between the top and bottom ends, together with the atomizing base 200, forms the atomizing chamber 107. The atomizing medium in the liquid storage chamber 101 is guided to the heating element 300 through the liquid guiding channel 311. The heating element 300 atomizes the atomizing medium and produces an aerosol at the atomizing surface 312. The aerosol fills the atomizing chamber 107. External airflow enters the atomizing chamber 107 to carry the aerosol and guide it to the suction port of the atomizer 1 for the user to inhale.

[0059] Optionally, the liquid guiding channel 311 is formed at the radial center of the heating element 300. It is understood that in other embodiments, the liquid guiding channel 311 may also be offset from the radial center of the heating element 300.

[0060] In some embodiments, the receiving cavity 103 is connected to the top and / or bottom of the heating element 300. For example, the receiving cavity 103 can be connected to the top of the heating element 300; or, the receiving cavity 103 can be connected to the bottom of the heating element 300; or, the receiving cavity 103 can be connected to both the top and bottom of the heating element 300. This arrangement ensures that the connection structure between the receiving cavity 103 and the heating element 300 does not affect the atomizing cavity 107, that is, the volume of the atomizing cavity 107 is not affected.

[0061] Specifically, when the receiving cavity 103 is connected to the heating element 300 through the connecting channel 104, the connecting channel 104 and the atomizing cavity 107 are spaced apart. The connecting channel 104 can be connected to the atomizing cavity 107 through the air passage 105, but the connecting channel 104 is not directly connected to the atomizing cavity 107, so that the atomizing medium in the connecting channel 104 will not leak into the atomizing cavity 107, that is, there will be no air inlet.

[0062] In some embodiments, please refer to Figure 15 The atomizer 1 also has a pressure-splitting chamber 106, which is located between the liquid storage chamber 101 and the heating element 300 to connect them. The volume of the pressure-splitting chamber 106 is smaller than the volume of the liquid storage chamber 101. By setting a relatively small pressure-splitting chamber 106 between the liquid storage chamber 101 and the heating element 300, the pressure-splitting chamber 106 is always filled with atomizing medium. During suction, a small amount of atomizing medium is consumed, which can quickly establish a negative pressure in the pressure-splitting chamber 106, thereby avoiding leakage during suction. As the consumption of atomizing medium continues to increase, air bubbles enter the pressure-splitting chamber 106. The air bubbles in the pressure-splitting chamber 106 are slowly discharged into the liquid storage chamber 101, and the atomizing medium in the liquid storage chamber 101 is replenished into the pressure-splitting chamber 106 to supply liquid to the heating element 300.

[0063] In some embodiments, please refer to Figure 15 The pressure-reducing chamber 106 is located at the bottom of the liquid storage chamber 101 and near the heating element 300. The top wall of the pressure-reducing chamber 106 has a first connecting hole 1061 communicating with the liquid storage chamber 101, and the side wall of the pressure-reducing chamber 106 near the bottom has a second connecting hole 1062 communicating with the liquid storage chamber 101. The atomizing medium in the liquid storage chamber 101 is generally introduced into the pressure-reducing chamber 106 through the first connecting hole 1061. When the atomizing medium in the liquid storage chamber 101 is almost completely consumed, the remaining atomizing medium at the bottom of the liquid storage chamber 101 can be completely introduced into the pressure-reducing chamber 106 through the second connecting hole 1062 to supply liquid to the heating element 300, thereby improving the utilization rate of the atomizing medium.

[0064] In this application, the positions of the ventilation channel 102 and the receiving cavity 103 can be set according to the actual type and specifications of the atomizer 1. The ventilation channel 102 can be formed in the main housing 100 of the atomizer 1, in the atomizing seat 200 of the atomizer 1, or it can be formed by the main housing 100 and the atomizing seat 200 of the atomizer 1 together. The receiving cavity 103 can be formed in the main housing 100 of the atomizer 1, in the atomizing seat 200 of the atomizer 1, or it can be formed by the main housing 100 and the atomizing seat 200 of the atomizer 1 together.

[0065] The specific structures of the air exchange channel 102 and the receiving cavity 103 are described in detail below according to different types of atomizers 1.

[0066] Example 1:

[0067] In this embodiment, please refer to Figures 1 to 8 The atomizer 1 includes a main housing 100 and an atomizing seat 200. The main housing 100 has a liquid storage chamber 101. The atomizing seat 200 is installed inside the main housing 100 and covers the bottom end of the liquid storage chamber 101. An air exchange channel 102 is formed in the atomizing seat 200, and a receiving cavity 103 is formed on the outer peripheral surface of the atomizing seat 200. In this embodiment, the atomizing seat 200 covers the bottom of the liquid storage chamber 101, and the atomizing seat 200 is directly connected to the liquid storage chamber 101. This allows the air exchange channel 102 to be directly formed in the atomizing seat 200, thus reducing the processing difficulty of the air exchange channel 102. At the same time, by forming the receiving cavity 103 on the outer peripheral surface of the atomizing seat 200, the processing difficulty of the receiving cavity 103 can also be reduced. In addition, the structure of the main housing 100 can be simplified, allowing the main housing 100 to be made into a slender cylindrical shape, making it convenient for users to carry and store.

[0068] In this embodiment, please refer to Figure 3 and Figure 4The heating element 300 is cylindrical, and has a liquid guiding channel 311 at its center that communicates with the liquid storage chamber 101. The inner circumferential surface of the heating element 300 is the liquid inlet surface, and the outer circumferential surface of the heating element 300 is the atomizing surface 312. The top and bottom ends of the heating element 300 are respectively installed on the atomizing base 200, and the portion of the heating element 300 located between the top and bottom ends together with the atomizing base 200 forms the atomizing chamber 107.

[0069] For details, please refer to Figure 8 The atomizing base 200 has a first mounting hole 210 and a second mounting hole 220 spaced apart along the axial direction of the atomizer 1, and a receiving cavity 230 communicating between the first mounting hole 210 and the second mounting hole 220. The first mounting hole 210 communicates with the liquid storage cavity 101, and the bottom end of the second mounting hole 220 is closed. The top end of the heating element 300 is interference-fitted into the first mounting hole 210, and the bottom end of the heating element 300 is interference-fitted into the second mounting hole 220. The top and bottom portions of the heating element 300 are placed in the receiving cavity 230, and the inner wall of the receiving cavity 230 and the outer wall of the heating element 300 enclose an atomizing cavity 107. The atomizing medium in the liquid storage cavity 101 enters the liquid guiding channel 311 through the top of the heating element 300, and the atomizing medium is absorbed and atomized by the heating element 300 to generate an aerosol in the atomizing cavity 107.

[0070] For details, please refer to Figure 2 , Figures 5 to 7 The atomizing base 200 also has an air intake channel 240 communicating with the atomizing chamber 107, through which external air enters the atomizing chamber 107. The main housing 100 also has an air outlet channel 110 communicating with the atomizing chamber 107, and a mouthpiece 400 is connected to the end of the main housing 100 opposite to the atomizing base 200, which communicates with the air outlet channel 110. External air enters the atomizing chamber 107 through the air intake channel 240 to carry away the aerosol, and is then delivered to the user's mouth through the air outlet channel 110 and the mouthpiece 400.

[0071] In this embodiment, the ventilation channel 102 and the receiving cavity 103 are both formed on the outer peripheral surface of the atomizing seat 200. The main housing 100 is cylindrical and is fitted over the atomizing seat 200 to cover the outer surfaces of the ventilation channel 102 and the receiving cavity 103.

[0072] In this embodiment, please refer to Figures 5 to 7 The ventilation channel 102 extends longitudinally from the top surface of the atomizing seat 200 to communicate with the receiving cavity 103. The receiving cavity 103 extends circumferentially along the atomizing seat 200. The air passage 105 and the ventilation channel 102 are respectively located at opposite ends of the receiving cavity 103 along the circumferential direction. The ventilation channel 102 is located above the receiving cavity 103, and the air passage 105 is located below the receiving cavity 103. This arrangement facilitates natural upward airflow and reduces airflow resistance.

[0073] In this embodiment, please refer to Figure 4 and Figure 5 The receiving cavity 103 is connected to the top end of the heating element 300. Along the transverse direction of the atomizer 1, the receiving cavity 103 and the top end of the heating element 300 are directly opposite each other. The connecting channel 104 extends radially from the circumferential center of the receiving cavity 103 to the outer peripheral surface of the heating element 300. This arrangement not only allows the atomizing medium in the receiving cavity 103 to be quickly guided to the outer peripheral surface of the heating element 300, but also reduces the manufacturing difficulty of the atomizing seat 200.

[0074] In this embodiment, please refer to Figure 6 Air passage 105 is formed on the outer peripheral surface of atomizing seat 200. Air passage 105 extends along the axial direction of atomizing seat 200. The top end of air passage 105 is connected to receiving cavity 103. The bottom end of air passage 105 is connected to atomizing cavity 107 through connecting port. Connecting port penetrates the side wall of atomizing seat 200.

[0075] In this embodiment, please refer to Figure 6 A blocking structure is formed at the port where the receiving cavity 103 connects to the airway 105. The blocking structure is used to prevent the atomizing medium in the receiving cavity 103 from flowing to the airway 105, while allowing the airflow in the airway 105 to enter the receiving cavity 103. The blocking structure ensures that even if the atomizer 1 is tilted, the atomizing medium in the receiving cavity 103 will not leak into the airway 105.

[0076] For details, please refer to Figure 6 The blocking structure includes a first blocking member 1031 and a second blocking member 1032. The first blocking member 1031 is formed on the bottom wall of the receiving cavity 103, and the second blocking member 1032 is formed on the top wall of the receiving cavity 103. The first blocking member 1031 is inclined upward from the bottom wall of the receiving cavity 103 in a direction away from the air passage 105, and the second blocking member 1032 is inclined downward from the top wall of the receiving cavity 103 in a direction away from the air passage 105. The first blocking member 1031 and the second blocking member 1032 are spaced apart along the circumference of the atomizing seat 200, and the first blocking member 1031 and the second blocking member 1032 are at least partially intersecting each other along the axial orthogonal projection of the atomizing seat 200. The above configuration allows the atomizer 1 to be positioned vertically or slightly tilted, so that the first blocking member 1031 can prevent the atomizing medium in the receiving cavity 103 from flowing into the air passage 105; and when the atomizer 1 is inverted or slightly tilted relative to it, the second blocking member 1032 can prevent the atomizing medium in the receiving cavity 103 from flowing into the air passage 105. It is understood that in other embodiments of this application, the blocking structure can also be of other types, such as a filter membrane that allows airflow but not liquid flow.

[0077] In this embodiment, please refer to Figure 3 and Figure 4 The heating element 300 includes a liquid guiding component 310 and a heating wire 320. The liquid guiding component 310 is cylindrical, with a liquid guiding channel 311 formed therein. The liquid inlet surface is the inner circumferential surface of the liquid guiding component 310, and the atomizing surface 312 is the outer circumferential surface of the liquid guiding component 310. The heating wire 320 is wound around the outer circumferential surface of the liquid guiding component 310 and has two connecting ends 321 extending out. The atomizer 1 also includes a connecting seat 500, an electrode 600, and an insulating component 700. The connecting seat 500 is connected to the atomizing seat 200, and the main housing 100 is fitted onto the top of the connecting seat 500. The electrode 600 is installed in the center hole at the bottom of the connecting seat 500 through the insulating component 700. One connecting end 321 is electrically connected to the positive electrode of the battery structure through the connecting seat 500, and the other connecting end 321 is electrically connected to the negative electrode of the battery structure through the electrode 600.

[0078] Specifically, the outer peripheral surface of the atomizing base 200 also forms two electrode grooves 250, and two connecting ends 321 respectively penetrate the side wall of the atomizing base 200 to extend downward along the two electrode grooves 250 to connect to the connecting base 500 and the electrode 600 respectively.

[0079] Specifically, the outer surface of the atomizing base 200 has an air inlet channel 240 that communicates with the atomizing chamber 107, and the atomizing base 200 and the connecting base 500 enclose an air chamber. The electrode 600 is cylindrical, and the external atmosphere enters the air chamber through the electrode 600 and enters the atomizing chamber 107 through the air inlet channel 240.

[0080] Example 2:

[0081] In Example 2, all the technical features of atomizer 1 are basically the same as those of atomizer in Example 1, except that: Please refer to Figure 9 The receiving cavity 103 is connected to the bottom end of the heating element 300. The atomizing seat 200 does not form a connecting channel 104 at the top position of the heating element 300, but the atomizing seat 200 has a connecting channel 104 at the bottom end of the heating element 300. The outer peripheral surface of the atomizing seat 200 also has an extension channel 260. The extension channel 260 extends from the center position of the receiving cavity 103 along the axial direction of the atomizing seat 200 to the connecting channel 104. The connecting channel 104 extends radially from the outer surface of the atomizing seat 200 to the bottom peripheral surface of the heating element 300.

[0082] Example 3:

[0083] All the technical features of atomizer 1 in Example 3 are basically the same as those of atomizer in Example 1, except that: Please refer to Figure 10The atomizer 1 does not have a receiving cavity 103. To prevent the atomizing medium in the ventilation channel 102 from leaking into the atomizing cavity 107, this embodiment not only extends the length of the ventilation channel 102 but also makes multiple bends in the ventilation channel 102. Specifically, the ventilation channel 102 includes a first ventilation section 1021, at least one second ventilation section 1022, and a third ventilation section 1023. The first ventilation section 1021 extends longitudinally from the top surface of the atomizing seat 200 to the second ventilation section 1022. The second ventilation section 1022 extends circumferentially along the outer peripheral surface of the atomizing seat 200. The third ventilation section 1023 extends longitudinally, and its bottom end is connected to the second ventilation section 1022 and communicates with the atomizing cavity 107.

[0084] Optionally, the outer surface of the atomizing base 200 has two second ventilation sections 1022. The two second ventilation sections 1022 are longitudinally spaced and interconnected. The upper second ventilation section 1022 is connected to the first ventilation section 1021, and the lower second ventilation section 1022 is connected to the third ventilation section 1023. It is understood that in other embodiments of this application, the number of second ventilation sections 1022 may be one, three, or more, and this is not a unique limitation.

[0085] Example 4:

[0086] All the technical features of atomizer 1 in Example 4 are basically the same as those of atomizer in Example 1, except that: Please refer to Figures 11 to 13 The atomizer 1 includes a main housing 100 and an atomizing seat 200. The main housing 100 has a liquid storage chamber 101 and an air exchange channel 102 formed therein. The atomizing seat 200 is installed in the main housing 100, and the atomizing seat 200 and the main housing 100 together form the aforementioned receiving cavity 103. In this embodiment, both the air exchange channel 102 and the receiving cavity 103 require processing of the structure of the main housing 100, making the structure of the main housing 100 relatively complex. This reduces the processing difficulty of the atomizing seat 200. This embodiment is mainly for atomizers 1 with relatively large capacity, improving user convenience.

[0087] In this embodiment, please refer to Figure 12 and Figure 13The main housing 100 also has an insertion interface 120 and a mounting cavity 130. The mounting cavity 130 and the liquid storage cavity 101 are spaced apart along the axial direction of the main housing 100. The insertion interface 120 connects the mounting cavity 130 and the liquid storage cavity 101. An atomizing seat 200 is mounted in the mounting cavity 130, and a heating element 300 is mounted in the atomizing seat 200. The top end of the atomizing seat 200 has an insertion portion 270, which is inserted into the insertion interface 120 and communicates with the liquid storage cavity 101. The liquid guiding channel 311 of the heating element 300 communicates with the liquid storage cavity 101 through the insertion portion 270. The outer surface of the atomizing seat 200 and the inner surface of the mounting cavity 130 together form the aforementioned receiving cavity 103. An air exchange channel 102 is formed in the main housing 100 and communicates with the receiving cavity 103.

[0088] For details, please refer to Figure 12 The top wall of the receiving cavity 103 extends longitudinally downward with a ventilation column 140, and the ventilation channel 102 penetrates the bottom wall of the liquid storage cavity 101 and the ventilation column 140. The ventilation column 140 is designed to guide the atomized medium leaking from the ventilation channel 102 to a position near the bottom of the receiving cavity 103.

[0089] In this embodiment, the connecting channel 104 extends from the outer surface of the atomizing seat 200 to communicate with the bottom outer peripheral surface of the heating element 300, and the bottom end of the ventilation column 140 is close to the inlet of the connecting channel 104, so that the ventilation column 140 can guide the atomizing medium to the connecting channel 104 and then to the heating element 300 through the connecting channel 104.

[0090] In this embodiment, please refer to Figure 12 and... Figure 13 The outer surface of the atomizing seat 200 protrudes from the airway column 280, which is perpendicular to the outer surface of the atomizing seat 200. The airway 105 penetrates the airway column 280 and the side wall of the atomizing seat 200. The airway column 280 is higher than the bottom end of the ventilation column 140. This prevents the atomized medium discharged from the ventilation column 140 from entering the airway column 280. Preferably, the airway column 280 is located at the upper-middle height of the receiving cavity 103, so that the receiving cavity 103 can store more atomized medium.

[0091] In this embodiment, please refer to Figure 12 and Figure 13 The battery structure 2 includes a battery rack 21, on which the battery is mounted. The battery rack 21 is connected to the main housing 100. The battery rack 21 seals the bottom of the mounting cavity 130 and is used to support the atomizing seat 200.

[0092] For details, please refer to Figure 12 and Figure 13 A sealing element 3 is installed on the battery holder 21, and the atomizing seat 200 is installed on the sealing element 3. The sealing element 3 is used to seal the mounting cavity 130.

[0093] Example 5:

[0094] All the technical features of atomizer 1 in Example 5 are basically the same as those of atomizer in Example 4, except that: Please refer to Figure 14 and Figure 15 The atomizer 1 also has a pressure-splitting chamber 106, which is located between the liquid storage chamber 101 and the heating element 300 to connect the liquid storage chamber 101 and the heating element 300. The volume of the pressure-splitting chamber 106 is smaller than the volume of the liquid storage chamber 101.

[0095] In this embodiment, please refer to Figure 15 The pressure-reducing chamber 106 is located at the bottom of the liquid storage chamber 101 and near the heating element 300. The top wall of the pressure-reducing chamber 106 has a first connecting hole 1061 communicating with the liquid storage chamber 101, and the side wall of the pressure-reducing chamber 106 near the bottom has a second connecting hole 1062 communicating with the liquid storage chamber 101. The atomizing medium in the liquid storage chamber 101 is generally introduced into the pressure-reducing chamber 106 through the first connecting hole 1061. When the atomizing medium in the liquid storage chamber 101 is almost completely consumed, the remaining atomizing medium at the bottom of the liquid storage chamber 101 can be completely introduced into the pressure-reducing chamber 106 through the second connecting hole 1062 to supply liquid to the heating element 300, thereby improving the utilization rate of the atomizing medium.

[0096] In this embodiment, please refer to Figure 15 A pressure-distributing wall 1063 extends from the bottom inner wall of the liquid storage chamber 101, forming a pressure-distributing cavity 106, which is penetrated through the bottom. An atomizing seat 200 is installed in the mounting cavity 130, with its top end sealing the bottom outer surface of the pressure-distributing cavity 106. The heating element 300 communicates with the pressure-distributing cavity 106.

[0097] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
