Description

Technical Field

[0001] This application belongs to the technical field of electronic atomization equipment, and particularly relates to an atomizer and an electronic atomization device. Background Technology

[0002] Currently, most electronic atomizing devices on the market consist of a main body and an atomizer mounted on the main body. The atomizer includes a mouthpiece, a coil, and a reservoir. The coil is connected to the mouthpiece via a tube, forming an atomization channel. When the electronic atomizing device is working, the coil in the atomizer heats the aerosol matrix stored in the reservoir to generate an aerosol, which is then output from the mouthpiece through the atomization channel.

[0003] Because the interior of the atomizing core is isolated from the interior of the liquid storage tank, a pressure difference can easily occur between the internal air pressure of the liquid storage tank and the internal air pressure of the atomizing core when the electronic atomizing device is in operation, which can easily cause the atomizer to leak.

[0004] Additionally, the atomizer, being a replaceable component, is detachably mounted on the main unit, allowing for extended battery life and flavor changes. When not in use (such as during transport or storage), upper and lower sealing plugs should be added to the mouthpiece and bottom of the atomizer, respectively, to prevent leakage. However, environmental changes causing temperature fluctuations or other factors that can deform the atomizer can lead to inconsistent air expansion and contraction within the liquid reservoir, creating a pressure difference that can cause leakage. Utility Model Content

[0005] The purpose of this application is to provide an atomizer and an electronic atomizing device to solve the technical problem that in existing atomizers, the internal air pressure of the liquid storage chamber and the internal air pressure of the atomizing core are prone to create a pressure difference, which leads to leakage.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] In a first aspect, embodiments of this application provide an atomizer, comprising:

[0008] The housing has a nozzle, and the interior of the housing contains an atomizing core and a liquid storage tank;

[0009] The atomizing core includes an atomizing tube. The inside of the housing is provided with a tube that communicates with the mouthpiece. The tube extends from the inner top wall of the housing toward the atomizing core and is inserted into the atomizing tube. The upper end of the atomizing tube is separated from the inner top wall of the housing to form a flow guiding gap.

[0010] A through groove extending along the length of the insertion tube is provided on the outer periphery of the insertion tube. The through groove and the inner wall of the atomizing tube form a pressure relief channel that connects the interior of the atomizing core with the liquid storage tank through the flow guide gap.

[0011] In this way, a pressure relief channel is formed between the insert and the atomizing tube inside the shell, which helps to balance the internal air pressure of the liquid storage chamber and the internal air pressure of the atomizing core, effectively improving the leakage problem caused by the pressure difference between the liquid storage chamber and the atomizing core.

[0012] An improvement is made to the structure of the insertion tube, which includes a first section communicating with the nozzle and a second section extending from the first section to the extension end of the insertion tube. The inner diameter of the second section is smaller than that of the first section, and the through groove is formed on the outer periphery of the first section. This reduces the inner diameter of the extension end of the insertion tube, facilitating easier insertion into the atomizing tube during assembly and improving installation efficiency. Furthermore, the formation of a ventilation space wider than the pressure relief channel between the outer periphery of the second section and the inner wall of the atomizing tube allows air to be gathered in the atomizing tube and flow from the pressure relief channel into the liquid storage chamber, enabling rapid equilibrium between the internal pressure of the atomizing tube and the internal pressure of the liquid storage chamber, thus improving the pressure relief effect.

[0013] In one embodiment, a reducing pipe section is provided between the first pipe section and the second pipe section. The outer periphery of the reducing pipe section is inclined from the first pipe section toward the second pipe section, and at least a portion of the through groove extends from the first pipe section to the reducing pipe section. This helps to eliminate the corners that are easily formed at the connection between the first and second pipe sections, thereby improving the smoothness of airflow and ensuring the pressure relief effect.

[0014] Another improvement to the structure of the insert is made: the inner diameter of the insert gradually decreases towards its extension end, allowing the inner diameter of the pressure relief channel to gradually increase from the upper end of the atomizing tube towards the extension end of the insert. This creates a pressure relief channel that gradually widens towards the depth of the atomizing tube, facilitating the accumulation of air in the atomizing tube within the pressure relief channel and its flow into the liquid storage chamber. This allows for rapid equilibrium between the internal air pressure of the atomizing tube and the internal air pressure of the liquid storage chamber, further improving the pressure relief effect. Additionally, the tapered tube structure of the insert facilitates easy insertion into the atomizing tube during assembly, improving installation efficiency.

[0015] In one embodiment, at least two symmetrically arranged through grooves are provided on the outer periphery of the insertion tube. Each through groove is respectively enclosed by a portion of the inner wall of the atomizing tube corresponding to its position, and respectively forms the pressure relief channel. In this way, a multi-channel communication structure is formed between the atomizing tube and the liquid storage tank, which is beneficial to improving the pressure relief effect.

[0016] The structure of the liquid storage chamber is improved by incorporating a liquid-absorbing sponge within it. This sponge fills the space between the outer wall of the atomizing tube and the inner wall of the housing. By using a liquid-absorbing sponge as the liquid storage medium within the storage chamber, the storage position of the liquid is effectively limited, preventing the liquid from easily flowing beyond the guide gap due to changes in the atomizer's orientation, thus effectively ensuring pressure relief.

[0017] In one embodiment, the liquid storage foam is separated from the inner top wall of the shell within the liquid storage chamber to form an isolation space. The isolation space is connected to the flow guide gap, thereby ensuring that the flow guide gap remains unobstructed. This effectively improves the situation where the liquid in the liquid storage chamber easily overflows the flow guide gap, ensuring the pressure relief effect of the pressure relief channel.

[0018] An improvement to the flow guide gap structure is made by providing a reinforcing ring within the housing to surround the outer periphery of the insertion tube. This reinforcing ring extends from the nozzle towards the upper end of the atomizing tube and is spaced apart from the upper end of the atomizing tube to form the flow guide gap. This allows the pressure relief channel to communicate with the liquid storage tank through the flow guide gap, ensuring effective pressure relief. Furthermore, the reinforcing ring inside the housing covering the insertion tube improves its structural strength.

[0019] Another improvement to the flow guide gap structure is made: the nozzle is a flat body on the top of the housing. This flat body creates an inner protrusion inside the housing. This inner protrusion is spaced apart from the upper end of the atomizing tube to form the flow guide gap. This ensures that the pressure relief channel can communicate with the liquid storage tank through the flow guide gap, allowing the pressure relief channel to function properly. Furthermore, the flat nozzle on the atomizer is easier for users to inhale, especially for users with smaller mouthpieces.

[0020] Secondly, this application also provides an electronic atomizing device, including a body and an atomizer, the atomizer being detachably mounted on the body. A power supply assembly is provided within the body, including a circuit board and a battery that supplies power to the atomizer. The atomizing coil in the atomizer is electrically connected to the circuit board. This allows the atomizer to be used as a replacement part, effectively enabling rapid battery life or flavor changes, thus improving the user experience.

[0021] The beneficial effects of the atomizer and electronic atomizing device provided in this application are as follows: Compared with the prior art, the pressure relief structure on the atomizer is improved. Inside the housing of the atomizer in this application, there is a tube for connecting to the atomizing core. This tube is inserted into the atomizing tube to form an atomizing channel connecting the mouthpiece and the atomizing core. A through groove is formed on the outer periphery of the tube. This through groove, together with the inner wall of the atomizing tube, forms a pressure relief channel that connects the interior of the atomizing core to the liquid storage tank, thereby balancing the internal air pressure of the atomizing core and the internal air pressure of the liquid storage tank.

[0022] Under normal operating conditions of the electronic atomizing device, the pressure relief channel on the atomizer of this application can balance the internal air pressure of the liquid storage chamber and the internal air pressure of the atomizing core, effectively improving the leakage problem caused by the pressure difference between the liquid storage chamber and the atomizing core.

[0023] Furthermore, when the atomizer is not in use, such as during packaging, transportation, or storage, a sealing plug is installed on the mouthpiece and a lower sealing plug is added to the bottom of the atomizer to ensure airtight storage. In the event of environmental changes causing temperature fluctuations or other factors that deform the atomizer, the pressure relief channel on this atomizer effectively prevents leakage caused by pressure differences resulting from inconsistent air expansion and contraction within the liquid reservoir.

[0044] 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. It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

[0045] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

[0046] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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.

[0047] 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.

[0048] In one related technology, a pressure relief structure is provided on the atomizer. This structure involves creating a pressure relief hole in the circumferential wall of the atomizing tube, which connects the interior of the atomizing tube to the liquid storage chamber, thereby achieving pressure balance between the interior of the atomizing tube and the liquid storage chamber. However, aerosol matrix in the liquid storage chamber can easily seep into the atomizing tube through the pressure relief hole, affecting the atomization effect; or the pressure relief hole can easily be blocked by the aerosol matrix, leading to pressure relief failure. Therefore, this method of creating a pressure relief hole in the circumferential wall of the atomizing tube requires adjusting the position of the pressure relief hole to be higher than the liquid inlet, and thus as high as possible above the liquid storage height of the liquid storage chamber. It is evident that this structure, which involves opening pressure relief holes on the circumferential wall of the atomizing tube, limits the amount of liquid that can be stored in the reservoir. Furthermore, since the liquid in the reservoir flows with the change in the atomizer's orientation, it can easily overflow the pressure relief holes on the circumferential wall of the atomizing tube. Therefore, it is impossible to completely prevent the liquid in the reservoir from easily blocking the pressure relief holes or flowing into the interior of the atomizing tube from the pressure relief holes.

[0049] In another related technology, a pressure relief hole is provided at the upper end of the atomizing tube. This structure overcomes the deficiency of the first related technology, which involves opening a pressure relief hole on the circumferential wall of the atomizing tube. However, this structure requires the upper end of the atomizing tube to have a certain thickness, or to add a structure that can be further processed, to achieve communication between the hole and the interior of the atomizing tube after the hole is opened. This means that the thickness of the atomizing tube needs to be increased, or a structure needs to be added to the upper end of the atomizing tube. These structures increase the space occupied and reduce the volume of the liquid storage tank. Therefore, this structure, which allows for a pressure relief hole at the upper end of the atomizing tube, is generally used in electronic atomizing devices that integrate an atomizer. For electronic atomizing devices where the atomizer is a replaceable component, this pressure relief structure is generally not used due to liquid storage capacity considerations.

[0050] Therefore, this application provides a novel atomizer and electronic atomizing device, which improves the pressure relief structure on the atomizer. This not only prevents the pressure relief hole from being easily blocked to ensure the pressure relief effect, but also reduces the space occupied by the pressure relief structure, thus ensuring the liquid storage capacity of the liquid reservoir. This effectively solves the problem that the internal air pressure of the liquid reservoir and the internal air pressure of the atomizing core in traditional electronic atomizing devices are prone to pressure difference, leading to leakage. The details are described below.

[0051] Please refer to the following: Figure 1 and Figure 2 An atomizer 100 includes at least a housing 1, an atomizing core 2, and a liquid storage chamber 3.

[0052] The housing 1 has a mouthpiece 11, and the inside of the housing 1 is provided with an atomizing core 2 and a liquid storage chamber 3. The atomizing core 2 is used to heat the liquid stored in the liquid storage chamber 3 when the electronic atomizing device is working normally, and generate aerosol that is output from the mouthpiece 11.

[0053] The atomizing core 2 includes an atomizing tube 21. The housing 1 also has an insert 4 communicating with the mouthpiece 11. This insert 4 extends from the inner top wall of the housing 1 towards the atomizing core 2 and is inserted into the atomizing tube 21. This can be understood as follows: inside the housing 1, there is an inwardly extending insert 4. One end of this insert 4 is connected to the mouthpiece 11 of the housing 1, and the other end extends towards the atomizing core 2 and is inserted into the atomizing tube 21 from its upper opening. This allows the mouthpiece 11 and the atomizing core 2 to communicate with each other, forming an atomization channel. During use, the aerosol generated by the atomizing core 2 will be output from this atomization channel to the mouthpiece 11. Thus, as... Figure 2 As shown, when the insertion tube 4 is inserted into the interior of the atomizing tube 21 from the upper end of the tube, the inner wall of the atomizing tube 21 will cover the outer periphery of the insertion part of the insertion tube 4.

[0054] Please refer to the following: Figure 2 , Figure 3 and Figure 4 The upper end of the atomizing tube 21 is separated from the inner top wall of the housing 1 so that a flow guide gap M is formed on the upper end of the atomizing tube 21, which can be connected to the liquid storage tank 3.

[0055] Please combine Figure 2 , Figure 4 and Figure 5 As shown ( Figure 5 The arrows in the diagram indicate the direction of airflow (this flow direction can also be reversed). A through groove 41 is provided on the outer periphery of the insertion tube 4. The through groove 41 extends along the length of the insertion tube 4, allowing the through groove 41 on the outer periphery of the insertion tube 4 to form a pressure relief channel 40 for air exchange with the inner wall of the atomizing tube 21. The pressure relief channel 40 is connected to the liquid storage chamber 3 through the flow guide gap M on the upper end of the atomizing tube 21, thereby connecting the atomizing core 2 and the liquid storage chamber 3, which is beneficial for balancing the internal air pressure of the atomizing core 2 and the internal air pressure of the liquid storage chamber 3.

[0056] Compared with the prior art, the atomizer 100 provided in this application improves the pressure relief structure of the atomizer 100. In this embodiment, the atomizer 100 housing 1 has an insert 4 for connecting to the atomizing core 2. The insert 4 is inserted into the atomizing tube 21 to form an atomization channel connecting the mouthpiece 11 and the atomizing core 2. A through groove 41 is formed on the outer periphery of the insert 4. This through groove 41 and the inner wall of the atomizing tube 21 form a pressure relief channel 40 that connects the interior of the atomizing core 2 with the liquid storage tank 3, thereby balancing the internal air pressure of the atomizing core 2 and the internal air pressure of the liquid storage tank 3.

[0057] Under normal operating conditions of the electronic atomizing device, the pressure relief channel 40 on the atomizer 100 of this application can balance the internal air pressure of the liquid storage chamber 3 and the internal air pressure of the atomizing core 2 in the atomizer 100, effectively improving the leakage problem caused by the pressure difference between the liquid storage chamber 3 and the atomizing core 2.

[0058] Furthermore, when the atomizer 100 is not in use, such as during packaging, transportation, or storage, a sealing plug is installed on the mouthpiece 11 of the atomizer 100, and a lower sealing plug is installed at the bottom of the atomizer 100 to achieve sealed storage. However, due to environmental changes causing temperature changes or other factors that cause deformation of the atomizer 100, the internal liquid storage chamber 3 of the atomizer 100 is prone to uneven expansion and contraction of air, resulting in a pressure difference and leakage. The pressure relief channel 40 provided on the atomizer 100 of this application can effectively prevent the leakage problem caused by the pressure difference that easily forms when the atomizer 100 is sealed.

[0059] Compared to the aforementioned related technologies, which involve opening pressure relief holes on the circumferential wall of the atomizing tube 21, this pressure relief structure limits the amount of liquid stored in the liquid storage chamber 3 and is prone to problems such as blockage leading to pressure relief failure. In the atomizer 100 provided in this application embodiment, a through groove 41 on the outer periphery of the insertion tube 4 and the inner wall of the atomizing tube 21 form a pressure relief channel 40, which is connected to the liquid storage chamber 3 through a flow guide gap M located at the upper end of the atomizing tube 21. The height difference is used to improve the problem of liquid in the liquid storage chamber 3 easily blocking or seeping into the pressure relief channel 40, effectively avoiding limitations on the amount of liquid stored in the liquid storage chamber 3, thereby ensuring the pressure relief effect.

[0060] Furthermore, compared to the aforementioned related technologies where a pressure relief hole is provided at the upper end of the atomizing tube 21, this pressure relief structure requires increasing the wall thickness of the atomizing tube 21 or adding a machinable structure to the upper end of the atomizing tube 21 to provide the pressure relief hole. This results in an increase in the volume of the atomizing tube 21 and a larger space occupied, thereby compressing the volume of the liquid storage chamber 3, which is not conducive to use in electronic atomizing devices with replaceable atomizers 100. In the atomizer 100 provided in this application embodiment, a pressure relief channel 40 is formed by the through groove 41 on the outer periphery of the insertion tube 4 and the inner wall of the atomizing tube 21. This allows the atomizing tube 21 to be made of thin-walled material, which helps to reduce the space occupied and ensures the volume of the liquid storage chamber 3 and the pressure relief effect. This is particularly beneficial for use in electronic atomizing devices with replaceable atomizers 100.

[0061] For the structure on cannula 4, please refer to one embodiment of this application. Figure 5 and Figure 6 The cannula 4 includes a first tube segment 42 connected to the suction nozzle 11 and a second tube segment 43 extending from the first tube segment 42 to the extension end port of the cannula 4. The "extension end port of the cannula 4" can be understood as the port on the cannula 4 away from the suction nozzle 11.

[0062] In this embodiment, when the insertion tube 4 is inserted into the atomizing tube 21, the first section 42 of the insertion tube 4 is interference-fitted with the inner wall of the atomizing tube 21 to achieve insertion and fixation. The through groove 41 is opened on the outer periphery of the first section 42, and part of the through groove 41 is enclosed with the inner wall of the atomizing tube 21 to form a pressure relief channel 40.

[0063] The inner diameter of the second pipe section 43 is smaller than that of the first pipe section 42. On the one hand, this makes the inner diameter of the extension end of the insertion tube 4 smaller, which is beneficial for the insertion tube 4 to be easily inserted into the atomizing tube 21 during the assembly process, thereby improving the installation efficiency.

[0064] On the other hand, a ventilation space wider than the pressure relief channel 40 is formed between the outer periphery of the second pipe section 43 and the inner wall of the atomizing pipe 21. This facilitates the gathering of air in the atomizing pipe 21 and its flow from the pressure relief channel 40 into the liquid storage tank 3, thereby enabling the internal air pressure of the atomizing pipe 21 and the internal air pressure of the liquid storage tank 3 to be quickly balanced, thus improving the pressure relief effect.

[0065] Regarding the structure of the aforementioned intubation tube 4, since the inner diameters of the first tube section 42 and the second tube section 43 of the intubation tube 4 are different, the connection between the two is prone to forming an angle. This angle can easily form a jamming angle that interferes with airflow in such a small space, affecting the pressure relief effect.

[0066] To address the aforementioned issues, please refer to one embodiment of this application. Figure 5 and Figure 6 Between the first tube section 42 and the second tube section 43 of the insertion tube 4, there is also a reducing tube section 44, and the outer periphery of the reducing tube section 44 can preferably be inclined from the first tube section 42 to the second tube section 43.

[0067] This helps to eliminate the corners that are easily formed at the connection between the first section 42 and the second section 43 of the insertion tube 4, thereby improving the smoothness of air flow and ensuring the pressure relief effect.

[0068] Among them, such as Figure 6 As shown, at least a portion of the through groove 41 on the outer periphery of the insertion tube 4 extends from the first tube section 42 to the reducing tube section 44, so that air in the ventilation space between the second tube section 43 and the inner wall of the atomizing tube 21 can quickly enter the through groove 41 and flow along the through groove 41 to the liquid storage tank 3, further accelerating the pressure balance and improving the pressure relief effect.

[0069] In another embodiment of this application (not shown), the inner diameter of the insertion tube 4 is gradually reduced in the direction of its extension end, so that the inner diameter of the pressure relief channel 40 can gradually increase from the upper end of the atomizing tube 21 towards the extension end of the insertion tube 4.

[0070] This design creates a pressure relief channel 40 that gradually widens towards the depth of the atomizing tube 21 between the outer periphery of the insertion tube 4 and the inner wall of the atomizing tube 21. This facilitates the accumulation of air in the atomizing tube 21 within the pressure relief channel 40, allowing it to flow into the liquid storage chamber 3. This enables rapid equilibrium between the internal air pressure of the atomizing tube 21 and the internal air pressure of the liquid storage chamber 3, thus improving the pressure relief effect. Furthermore, the tapered structure of the insertion tube 4 facilitates easy insertion into the atomizing tube 21 during assembly, improving installation efficiency.

[0071] Regarding the layout of the through slot 41 on the cannula 4, please refer to one embodiment of this application. Figure 5 and Figure 7The outer periphery of the insertion tube 4 is provided with at least two symmetrically arranged through grooves 41, each through groove 41 enclosing the inner wall portion of the atomizing tube 21 corresponding to its position, and forming a pressure relief channel 40.

[0072] In this embodiment, please refer to Figure 5 and Figure 7 As shown, two through grooves 41 are preferably provided on the outer periphery of the insertion tube 4. These two through grooves 41 are symmetrically arranged on the outer periphery of the insertion tube 4, and each of the two through grooves 41 encloses a portion of the inner wall of the corresponding atomizing tube 21, thereby forming two symmetrically positioned pressure relief channels 40 between the outer periphery of the insertion tube 4 and the inner wall of the atomizing tube 21. In this way, a multi-channel communication structure is formed between the atomizing tube 21 and the liquid storage tank 3, which is beneficial to improving the pressure relief effect.

[0073] In other embodiments (not shown in the figures), four through grooves 41 are preferably provided on the outer periphery of the insertion tube 4. These four through grooves 41 are evenly distributed and symmetrically arranged on the outer periphery of the insertion tube 4, and respectively enclose the inner wall portion of the corresponding atomizing tube 21, thereby forming a cross-shaped symmetrical pressure relief channel 40 between the outer periphery of the insertion tube 4 and the inner wall of the atomizing tube 21. In this way, a multi-directional and multi-channel communication structure is formed between the atomizing tube 21 and the liquid storage tank 3, further improving the pressure relief effect.

[0074] In practical applications, the atomizer 100 is prone to unpredictable placement during transportation and storage, making it susceptible to being placed upside down or tilted. This means that the liquid level of the aerosol matrix stored in the liquid storage chamber 3 can easily exceed the flow guide gap M, blocking the pressure relief channel 40 and causing pressure relief failure.

[0075] Therefore, the internal structure of the liquid storage tank 3 can be improved. In one embodiment of this application, please refer to... Figure 8 Inside the liquid storage chamber 3, there is a liquid storage sponge 31 for absorbing the stored liquid. The liquid storage sponge 31 fills the space between the outer wall of the atomizing tube 21 and the inner wall of the shell 1. In this embodiment, the liquid storage sponge 31 can preferably be a cylindrical liquid-absorbing sponge, which is beneficial to match the shape of the liquid storage chamber 3 in the atomizer 100 of this application.

[0076] Therefore, by setting a cotton body with liquid absorption function as the liquid storage medium in the liquid storage chamber 3, it is beneficial to limit the storage position of the liquid and prevent the liquid in the liquid storage chamber 3 from flowing and overflowing the guide gap M due to the change in the posture of the atomizer 100, thus effectively ensuring the pressure relief effect.

[0077] Preferably, such as Figure 8 As shown, the liquid storage sponge 31 is separated from the inner top wall of the shell 1 in the liquid storage chamber 3 to form an isolation space N, which is connected to the flow guide gap M.

[0078] In this embodiment, an isolation space N is formed by separating the top of the liquid storage sponge 31 in the liquid storage tank 3 from the inner top wall of the shell 1. The isolation space N is connected to the flow guide gap M, so that the flow guide gap M can be kept unobstructed, effectively improving the situation where the liquid in the liquid storage tank 3 easily overflows the flow guide gap M, thereby ensuring the pressure relief effect of the pressure relief channel 40.

[0079] For the specific structure of the flow-guiding gap M formed within the housing 1, please refer to one embodiment of this application. Figure 9 The housing 1 is also provided with a reinforcing ring 12 for surrounding the outer periphery of the insertion tube 4. The reinforcing ring 12 extends from the nozzle 11 to the upper end of the atomizing tube 21 and is separated from the upper end of the atomizing tube 21 to form a flow guiding gap M.

[0080] On the one hand, the reinforcing ring 12 inside the shell 1 covers the insertion tube 4, which helps to improve the structural strength of the insertion tube 4.

[0081] On the other hand, after the insertion tube 4 is inserted into the atomizing tube 21, the upper end of the atomizing tube 21 is separated from the end of the reinforcing ring 12, thereby forming a flow guide gap M that communicates with the liquid storage tank 3, so that the pressure relief channel 40 can communicate with the liquid storage tank 3 through the flow guide gap M, ensuring the pressure relief effect of the pressure relief channel 40.

[0082] For the specific structure of the flow-guiding gap M formed within the housing 1, please refer to another embodiment of this application. Figure 1 and Figure 10 The nozzle 11 on the atomizer 100 is a flat body on the top of the housing 1. The flat body forms an inner protrusion 13 inside the housing 1. The inner protrusion 13 is separated from the upper end of the atomizing tube 21 to form a clearance space, which is a flow guide gap M.

[0083] On the one hand, the nozzle 11 on the atomizer 100 is preferably a flat shape on the top of the housing 1, which is beneficial for users to put it in their mouths, especially for users with smaller mouths.

[0084] On the other hand, the nozzle 11 is flat so that there are protrusions 13 inside the housing 1. These protrusions 13 on the housing 1 can be separated from and cooperate with the upper end of the atomizing tube 21 to form a flow guide gap M, so as to ensure that the pressure relief channel 40 can be connected to the liquid storage tank 3 through the flow guide gap M, so that the pressure relief channel 40 can play a normal pressure relief role.

[0085] Please refer to the following: Figure 11 and Figure 12 This application also provides an electronic atomizing device, including a body 200 of the electronic atomizing device and an atomizer 100 provided in this application embodiment, wherein the atomizer 100 is detachably mounted on the body 200.

[0086] The main body 200 contains a power supply component 5, which includes a circuit board 51 and a battery 52 that supplies power to the atomizer 100. The atomizing coil 2 in the atomizer 100 is electrically connected to the circuit board 51. Figure 12 As shown, in the atomizer 100 of this application embodiment, the atomizing core 2 also includes a heating element 22 with electrodes. When the atomizer 100 is installed on the body 200 of the electronic atomizing device, the electrodes on the heating element 22 can be electrically connected to the circuit board 51 to realize corresponding control and power supply connection.

[0087] In this way, the atomizer 100 can be used as a replacement part, effectively achieving rapid battery life or flavor changes, and improving the user experience. The atomizer 100 provided in this application embodiment can be packaged and stored separately. Especially when the atomizer 100 is packaged with upper and lower sealing plugs, since the atomizer 100 in this application embodiment has the aforementioned pressure relief structure, it is beneficial to prevent leakage caused by air pressure differences due to temperature changes or other factors that cause deformation of the atomizer 100 caused by environmental changes.

[0088] 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.
