Description

Technical Field

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

[0002] The core components of an electronic atomizing device include the atomizer and the power supply module. The power supply module provides electrical energy to the atomizer, which heats the atomizer coil inside the atomizer, heating the aerosol matrix in the reservoir to generate an aerosol that the user can inhale. When the atomizer coil reaches the end of its lifespan, the user needs to discard the entire reservoir and atomizer coil together and replace them with new components. This usage method increases the operating cost of the electronic atomizing device.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0004] The purpose of this application is to provide an atomizer and an electronic atomizing device, which aims to solve the technical problem in the related art that when the atomizer core reaches the end of its service life, the user has to discard the entire liquid storage tank and the atomizer core together, which increases the cost of using the electronic atomizing device.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows: This application provides an atomizer, including: a housing, a liquid inlet assembly, and an atomizing core; The housing has a liquid storage chamber and an installation chamber. The liquid storage chamber is used to store the aerosol matrix. The housing has a first liquid outlet hole that connects the liquid storage chamber and the installation chamber. The liquid inlet assembly is disposed in the mounting cavity. The liquid inlet assembly has an insertion cavity and a first liquid inlet hole. The insertion cavity is connected to the first liquid inlet hole. The liquid inlet assembly can move in a straight line so that the first liquid inlet hole and the first liquid outlet hole are disconnected or connected. The atomizing core can be inserted into the insertion cavity for a detachable connection with the liquid inlet assembly; The aerosol matrix stored in the liquid storage chamber can flow into the atomizing core sequentially through the first liquid outlet and the first liquid inlet.

[0006] By adopting the above solution, this application detachably connects the atomizer core and the liquid inlet assembly. This allows users to replace only the atomizer core when it reaches the end of its lifespan, without discarding other parts of the atomizer, thus reducing operating costs. This modular design makes the atomizer core an independent consumable, extending the lifespan of the liquid reservoir. The liquid inlet assembly can move linearly to control the connection or disconnection between the first liquid inlet and the first liquid outlet, thereby achieving on-demand supply of the aerosol matrix. The atomizer core is detachably inserted into the insertion cavity. This design facilitates quick replacement by users, improving the user experience, and reduces the risk of aerosol matrix leakage during atomizer core replacement, contributing to improved overall sealing and reliability of the atomizer.

[0007] In some implementations, the liquid inlet assembly includes a support tube and a sealing sleeve, the sealing sleeve covering the support tube, and the first liquid inlet hole is formed on the support tube and the sealing sleeve; In this configuration, at least a portion of the inner wall of the support tube is covered by the sealing sleeve to create a sealed fit between the sealing sleeve and the atomizing core, and at least a portion of the outer wall of the support tube is covered by the sealing sleeve to create a sealed fit between the sealing sleeve and the mounting cavity.

[0008] By adopting the above solution, the sealing sleeve wraps around the inner and outer walls of the support tube, forming a multi-layer sealing structure. This effectively prevents leakage of the aerosol matrix when the first inlet and the first outlet are connected, and also prevents leakage when the atomizing core is connected to the inlet assembly. The first inlet is formed on the support tube and the sealing sleeve, ensuring a smooth transmission path for the aerosol matrix from the storage chamber to the atomizing core.

[0009] In some implementations, the sealing sleeve has a first protrusion, a second protrusion, and a third protrusion arranged sequentially at intervals along the axial direction of the support tube. The first protrusion, the second protrusion, and the third protrusion are all annular and are located outside the support tube. The sealing sleeve has two fourth protrusions spaced apart along the axial direction of the support tube. The fourth protrusions are both annular and are located inside the support tube. In the axial direction of the support tube, the first liquid inlet is located between the first protrusion and the second protrusion, and the first liquid inlet is also located between two adjacent fourth protrusions.

[0010] By adopting the above scheme, the first, second, and third protrusions form three annular sealing barriers outside the support tube, enhancing the sealing between the liquid inlet assembly and the housing. The first and second protrusions limit the liquid flow range when the first liquid inlet and the first liquid outlet are connected, preventing the aerosol matrix from spreading to other areas. When the liquid inlet assembly moves in a straight line, positioning the first liquid outlet between the second and third protrusions, the connection between the first liquid outlet and the first liquid inlet can be achieved, preventing the aerosol matrix from leaking from the first liquid outlet into non-designed areas. The two fourth protrusions located inside the support tube ensure that the aerosol matrix flows directly into the atomizing core, preventing leakage into non-designed areas of the insertion cavity.

[0011] In some implementations, one of the housing and the support tube has a guide block, and the other of the housing and the support tube has a guide groove. The guide block is movable along the guiding direction of the guide groove so that the liquid inlet assembly can move in a straight line.

[0012] By adopting the above scheme, a clear trajectory constraint can be provided for the linear movement of the liquid inlet assembly, ensuring that the first liquid inlet and the first liquid outlet can be precisely aligned during movement. Furthermore, after the atomizing core is in contact with the liquid inlet assembly, rotating the atomizing core can also restrict the rotation of the liquid inlet assembly relative to the housing, thereby ensuring the alignment of the first liquid inlet and the first liquid outlet. The linear movement design of the guide structure allows the liquid inlet assembly to stably switch between "connected" and "disconnected" states, controlling the flow of the aerosol matrix from the storage chamber to the atomizing core.

[0013] In some implementations, the atomizer further includes an elastic element for disengaging the first inlet port on the liquid inlet assembly from the first outlet port.

[0014] By adopting the above solution, the elastic element ensures that the first liquid inlet and the first liquid outlet remain disconnected in the atomizer when there is no atomizing core, effectively preventing accidental leakage of the aerosol matrix when not in use; this automatic cut-off mechanism improves the safety of atomizer use. The elastic element, combined with the multiple protrusions (second and third protrusions) on the sealing sleeve, further guarantees the sealing effect when the first liquid inlet and the first liquid outlet are disconnected.

[0015] In some implementations, the liquid inlet assembly has a second guide ramp that surrounds the opening of the insertion cavity.

[0016] By adopting the above solution, the atomizer core can be guided to automatically align with the center of the insertion cavity during insertion, reducing insertion difficulties caused by angular deviation or improper operation, and making the insertion process of the atomizer core smoother.

[0017] In some implementations, the housing includes an outer shell and an inner support, the outer shell cooperating with the inner support to form the liquid storage cavity and the mounting cavity.

[0018] By adopting the above solution, the separate arrangement between the outer shell and the inner support is beneficial to the manufacturing of the shell.

[0019] In some implementations, the mounting cavity includes a first sub-cavity and a second sub-cavity, the diameter of the first sub-cavity being smaller than the diameter of the second sub-cavity, and the liquid inlet assembly being disposed in the second sub-cavity; the first sub-cavity is used to guide the atomizing core to be inserted into the insertion cavity.

[0020] By adopting the above scheme, the smaller diameter of the first sub-cavity serves as a guide channel for the insertion of the atomizing core, ensuring precise alignment and smooth entry of the atomizing core into the insertion cavity. The larger diameter of the second sub-cavity provides ample space for the installation and linear movement of the liquid inlet assembly, while also accommodating structures such as elastic components. Furthermore, the smaller diameter of the first sub-cavity also allows for a larger volume of the liquid storage chamber, enabling it to store more aerosol matrix.

[0021] In some implementations, the atomizer further includes a mouthpiece, which is fixedly connected to the atomizing core, and the atomizing core has a second liquid inlet. One of the nozzle and the housing has a positioning groove, and the other of the nozzle and the housing has a positioning protrusion; When the positioning protrusion is located within the positioning groove, the first liquid inlet hole is connected to the second liquid inlet hole.

[0022] By adopting the above solution, the cooperation between the positioning protrusion and the positioning groove can reduce the possibility of the process nozzle rotating relative to the housing, and reduce the problem of poor liquid transmission caused by misalignment between the first liquid inlet and the second liquid inlet.

[0023] In some implementations, the nozzle has a first guide ramp, the length of which extends circumferentially along the nozzle. The positioning protrusion or the positioning groove is disposed on the first guide slope.

[0024] By adopting the above scheme, the first guide slope extends circumferentially along the nozzle to form a continuous inclined surface, which can guide the positioning protrusion into the positioning groove when the nozzle and atomizing core are inserted into the housing, so as to realize the limiting between the positioning protrusion and the positioning groove, so as to ensure the connection between the second liquid inlet hole and the first liquid inlet hole of the atomizing core, and avoid the liquid transmission obstruction caused by installation deviation.

[0025] In some implementations, the nozzle has a first channel, the inner wall of the first channel has a first slot, the outer surface of the atomizing core has a first stage, and the first stage is located in the first slot.

[0026] By adopting the above solution, the stability of the connection between the mouthpiece and the atomizer core can be guaranteed, and the possibility of separation between the mouthpiece and the atomizer core during the process of pulling out the atomizer core can be reduced.

[0027] In some implementations, the atomizing core includes a shell, a heating element, and a first liquid-absorbing element; the first liquid-absorbing element encloses the heating element, and the first liquid-absorbing element and the heating element are installed in the shell cavity of the shell; the atomizing core also includes a conductive electrode, and the heating element is electrically connected to the conductive electrode; the conductive electrode is fixedly connected to the shell.

[0028] By adopting the above scheme, the tube shell can provide support for the heating element and the first liquid suction element, reducing the possibility of deformation of the heating element during insertion and removal; while the first liquid suction element can continuously absorb aerosol matrix from the liquid storage chamber and supply it to the heating element, thereby reducing the possibility of dry burning of the heating element; the atomizing core is electrically connected to the power supply component, which can supply power to the heating element.

[0029] In some implementations, the outer surface of the tube shell has a limiting wing. When the atomizing core is inserted into the cavity, the limiting wing abuts against the liquid inlet assembly, so that the liquid inlet assembly is in a connected state.

[0030] By adopting the above solution, it can be ensured that the liquid inlet assembly is in a connected state.

[0031] This application provides an electronic atomizing device, including: a power supply component and an atomizer as described in any of the above implementations, wherein the atomizer is connected to the power supply component.

[0032] By adopting the above solution, after the atomizer is applied to an electronic atomization device, the atomizer coil and the liquid inlet assembly are detachably connected. This allows users to replace only the atomizer coil when it reaches the end of its lifespan, without discarding other parts of the atomizer, thus reducing operating costs. This modular design makes the atomizer coil an independent consumable, extending the lifespan of the liquid reservoir. The liquid inlet assembly can move linearly to control the connection or disconnection between the first liquid inlet port and the first liquid outlet port, thereby achieving on-demand supply of the aerosol matrix. The detachable insertion of the atomizer coil into the insertion cavity facilitates quick replacement by users, improving the user experience, and reduces the risk of aerosol matrix leakage during coil replacement, contributing to improved overall sealing and reliability of the atomizer.

[0033] In some implementations, the bottom of the mounting cavity has a first air inlet, and the power supply assembly includes a second liquid suction element, which is disposed opposite to the first air inlet.

[0034] By adopting the above solution, the second liquid-absorbing component can absorb the aerosol matrix that may leak out during the replacement of the atomizing core, or other liquids generated during use, thereby ensuring the safety of the power supply component. Attached Figure Description

[0038] In related technologies, the core components of an electronic atomizing device include the atomizer and the power supply module. The power supply module provides electrical energy to the atomizer, driving the atomizer core inside to heat up, which in turn heats the aerosol matrix in the reservoir, generating an aerosol that the user can inhale. In the design of electronic atomizing devices, the reservoir and atomizer core are usually not detachable, making it suitable for disposable use. However, this design presents several problems in practical use. First, during storage or transportation, especially in high-altitude environments, the aerosol matrix in the reservoir is prone to leakage due to pressure changes, affecting the reliability of the device and the user experience. Second, when the atomizer core reaches the end of its lifespan, the user must discard the entire reservoir and atomizer core together and replace them with new components. However, the reservoir usually still has usability at this point, and this complete replacement leads to waste of the reservoir and increases the cost of using the electronic atomizing device. Furthermore, because the reservoir and atomizer core are not detachable, users cannot replace the atomizer core or reservoir separately, further exacerbating resource waste.

[0039] Therefore, this application provides an atomizer 100 and an electronic atomizing device to solve the problems in the related art.

[0040] 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.

[0041] Combination Figures 1 to 3 As shown in the figure, this application provides an electronic atomizing device, including a power supply component 200 and an atomizer 100, wherein the atomizer 100 is connected to the power supply component 200. The power supply component 200 can supply power to the atomizer 100 to atomize the aerosol matrix stored in the atomizer 100 to generate an aerosol. It is understood that the connection between the power supply component 200 and the atomizer 100 can be a detachable connection or a non-detachable connection, that is, the power supply component 200 and the atomizer 100 are integrated into one unit.

[0042] Combination Figure 1 , Figure 4 and Figure 5As shown, in this embodiment of the application, the atomizer 100 includes a housing 101, a liquid inlet assembly 102, and an atomizing core 103. The housing 101 has a liquid storage chamber 104 and a mounting chamber 105. The liquid storage chamber 104 is used to store the aerosol matrix. The housing 101 has a first liquid outlet hole 106 that connects the liquid storage chamber 104 and the mounting chamber 105. The liquid inlet assembly 102 is disposed in the mounting chamber 105. The liquid inlet assembly 102 has an insertion chamber 107 and a first liquid inlet hole 108. The insertion chamber 107 is connected to the first liquid inlet hole 108. The liquid inlet assembly 102 can move in a straight line so that the first liquid inlet hole 108 and the first liquid outlet hole 106 are disconnected or connected. The atomizing core 103 can be inserted into the insertion chamber 107 to be detachably connected to the liquid inlet assembly 102. The aerosol matrix stored in the liquid storage chamber 104 can flow into the atomizing core 103 sequentially through the first liquid outlet hole 106 and the first liquid inlet hole 108.

[0043] In this embodiment, the atomizer 100 detachably connects the atomizing core 103 to the liquid inlet assembly 102. This allows users to replace only the atomizing core 103 when it reaches the end of its service life, without discarding other parts of the atomizer 100, thus reducing operating costs. This modular design makes the atomizing core 103 an independent consumable, extending the service life of the liquid reservoir. The liquid inlet assembly 102 can move linearly to control the connection or disconnection between the first liquid inlet port 108 and the first liquid outlet port 106, thereby achieving on-demand supply of the aerosol matrix. The atomizing core 103 is detachably inserted into the insertion cavity 107. This design facilitates quick replacement by the user, improves the user experience, and reduces the risk of aerosol matrix leakage during the replacement of the atomizing core 103, contributing to improved overall sealing and reliability of the atomizer 100.

[0044] For ease of description, the length direction of the electronic atomizing device is defined as the AA direction. The length direction of the atomizer 100 and the length direction of the atomizing core 103 are parallel to the length direction of the electronic atomizing device, and the linear motion direction of the liquid inlet assembly 102 is also parallel to the length direction of the atomizer 100.

[0045] See Figure 1 and Figure 5As shown, in some embodiments, the housing 101 and the power supply component 200 can be connected by a snap-fit ​​mechanism. For example, the housing 101 has a second locking platform 110, and the power supply component 200 has a locking hole 201. The second locking platform 110 snaps into the locking hole 201, achieving a snap-fit ​​connection between the housing 101 and the power supply component 200. It is understood that the housing 101 and the power supply component 200 can also be bonded together for fixation. The liquid inlet assembly 102 functions as a switch to open or close the first liquid outlet 106. When the atomizing core 103 is inserted into the preset position in the insertion cavity 107 of the liquid inlet assembly 102, the liquid inlet assembly 102 moves to the bottom of the mounting cavity 105, abutting against the bottom of the mounting cavity 105. This prevents the liquid inlet assembly 102 from continuing its linear movement. At this point, the first liquid outlet 106 connects to the first liquid inlet 108, which in turn connects to the atomizing core 103, allowing the aerosol matrix to flow into the atomizing core 103. The detachable connection between the atomizing core 103 and the liquid inlet assembly 102 is a plug-and-play method, facilitating the installation and removal of the atomizing core 103. Furthermore, during the insertion and removal of the atomizing core 103, the liquid inlet assembly 102 always controls the opening and closing of the first liquid outlet 106, significantly reducing the possibility of aerosol matrix leakage.

[0046] In this embodiment, the liquid inlet assembly 102 has a connected state and a disconnected state; see also Figure 5 and Figure 16 As shown, in the connected state, the first liquid outlet 106 and the first liquid inlet 108 are connected; during the process of switching from the connected state to the disconnected state, the liquid inlet assembly 102 moves along the length direction of the atomizer 100, causing the first liquid outlet 106 and the first liquid inlet 108 to gradually misalign in the length direction of the atomizer 100; combined with Figures 6 to 8 ,as well as Figure 17 and Figure 18 As shown, in the disconnected state, the first liquid outlet 106 and the first liquid inlet 108 are completely misaligned and no longer connected. After the atomizing core 103 is connected to the liquid inlet assembly 102, the liquid inlet assembly 102 is in the connected state. After the atomizing core 103 is pulled out of the liquid inlet assembly 102, the liquid inlet assembly 102 switches from the connected state to the disconnected state.

[0047] See Figure 1 As shown, in some embodiments, the atomizer 100 also includes a mouthpiece 111, which is fixedly connected to the atomizing core 103, thus facilitating the insertion and removal of the atomizing core 103.

[0048] Combination Figure 8 , Figure 10 and Figure 11As shown, in some embodiments, the liquid inlet assembly 102 includes a support tube 112 and a sealing sleeve 113. An insertion cavity 107 is formed in the support tube 112, and a first liquid inlet hole 108 is formed on the support tube 112 and the sealing sleeve 113. The sealing sleeve 113 wraps around the support tube 112, wherein at least a portion of the inner wall of the support tube 112 is covered by the sealing sleeve 113, and at least a portion of the outer wall of the support tube 112 is covered by the sealing sleeve 113. By wrapping the inner and outer walls of the support tube 112 with the sealing sleeve 113, a multi-layer sealing structure can be formed, effectively preventing leakage of the aerosol matrix when the first liquid inlet hole 108 is connected to the first liquid outlet hole 106, and preventing leakage when the atomizing core 103 is connected to the liquid inlet assembly 102. The first liquid inlet hole 108, formed on the support tube 112 and the sealing sleeve 113, can ensure that the transmission path of the aerosol matrix from the liquid storage chamber 104 to the atomizing core 103 is unobstructed. For example, the support tube 112 can be made of rigid plastic, such as PC (Polycarbonate), PET (Polyethylene Terephthalate), PETG (Polyethylene Terephthalate Glycol-modified), PCTG (Poly-Cyclohexylenedimethylene Terephthalate Glycol-modified), or PCT (Polycyclohexylene Dimethylene Terephthalate). The sealing sleeve 113 can be made of silicone or rubber. The support tube 112 includes a sealing part 114 and an exposed part 115, which are connected and can be integrally molded to form a single structure. The outer wall of the support tube 112 has a limiting boss 116, which is annular, thus limiting the sealing sleeve 113. The sealing sleeve 113 is fitted onto the sealing part 114 of the support tube 112. The first liquid inlet 108 includes a through hole in the sealing sleeve 113 and a through hole in the support tube 112, which are combined to form the first liquid inlet 108. There can be one or more first liquid inlets 108. When there are multiple first liquid inlets 108, they are evenly distributed around the circumference of the support tube 112, which helps to achieve uniform flow of the aerosol matrix to the atomizing core 103. The number of first liquid outlets 106 is equal to the number of first liquid inlets 108. When the liquid inlet assembly 102 is in a connected state, the position of the first liquid outlet 106 corresponds to the position of the first liquid inlet 108.

[0049] Combination Figure 5 and Figure 8As shown, in some embodiments, the sealing sleeve 113 has a first protrusion 117, a second protrusion 118, and a third protrusion 119 arranged sequentially at intervals along the axial direction of the support tube 112. The first protrusion 117, the second protrusion 118, and the third protrusion 119 are all annular and are located outside the support tube 112. The sealing sleeve 113 also has two fourth protrusions 120 arranged at intervals along the axial direction of the support tube 112. The fourth protrusions 120 are all annular and are located inside the support tube 112. In the axial direction of the support tube 112, a first liquid inlet 108 is located between the first protrusion 117 and the second protrusion 118, and the first liquid inlet 108 is also located between two adjacent fourth protrusions 120. Thus, the first protrusion 117, the second protrusion 118, and the third protrusion 119 form three annular sealing barriers outside the support tube 112, enhancing the sealing between the liquid inlet assembly 102 and the housing 101. The first protrusion 117 and the second protrusion 118 limit the liquid flow range when the first liquid inlet hole 108 and the first liquid outlet hole 106 are connected, preventing the aerosol matrix from spreading to other areas. When the liquid inlet assembly 102 moves in a straight line, so that the first liquid outlet hole 106 is located between the second protrusion 118 and the third protrusion 119, the connection between the first liquid outlet hole 106 and the first liquid inlet hole 108 can be achieved, thus preventing the aerosol matrix from leaking from the first liquid outlet hole 106 into non-designed areas. The two fourth protrusions 120 located inside the support tube 112 ensure that the aerosol matrix flows directly into the atomizing core 103, preventing the aerosol matrix from leaking into non-designed areas of the insertion cavity 107. It should be noted that the number of the fourth protrusion 120 is not limited to two; it can also be three, four, or five, etc.

[0050] Combination Figure 5 and Figure 8 As shown, exemplarily, the axial direction of the support tube 112 is parallel to the length direction of the atomizer 100; along the axial direction of the support tube 112, the first protrusion 117 is close to the mouthpiece 111, while the third protrusion 119 is far from the mouthpiece 111, that is, the distance between the first protrusion 117 and the mouthpiece 111 is less than the distance between the third protrusion 119 and the mouthpiece 111. When the liquid inlet assembly 102 is in the disconnected state, the first liquid outlet 106 is located between the second protrusion 118 and the third protrusion 119, and at this time, the first liquid outlet 106 is disconnected from the first liquid inlet 108. When the liquid inlet assembly 102 is in the connected state, the first liquid outlet 106 is located between the first protrusion 117 and the second protrusion 118, and the first liquid outlet 106 is connected to the first liquid inlet 108.

[0051] Combination Figures 19 to 22As shown, in some embodiments, one of the housing 101 and the support tube 112 has a guide block 121, and the other of the housing 101 and the support tube 112 has a guide groove 122. The guide block 121 can move along the guiding direction of the guide groove 122, so that the liquid inlet assembly 102 can move in a straight line. This provides a clear trajectory constraint for the linear movement of the liquid inlet assembly 102, ensuring that the first liquid inlet hole 108 and the first liquid outlet hole 106 can be precisely aligned during movement. In addition, after the atomizing core 103 is in contact with the liquid inlet assembly 102, when the atomizing core 103 is rotated, the rotation of the liquid inlet assembly 102 relative to the housing 101 can also be restricted, thereby ensuring that the first liquid inlet hole 108 and the first liquid outlet hole 106 are aligned. The linear movement design of the guiding structure enables the liquid inlet assembly 102 to stably switch between the two states of "connection" and "disconnection", controlling the flow of the aerosol matrix from the liquid storage chamber 104 to the atomizing core 103. For example, the support tube 112 may have a guide block 121, and the housing 101 may have a guide groove 122; the guide block 121 is inserted into the guide groove 122, and the guide groove 122 may be a through hole structure opened on the housing 101; the number of guide blocks 121 may be multiple, and the number of guide grooves 122 is equal to the number of guide blocks 121. The number of guide blocks 121 may be 2, 3 or 4. Multiple guide blocks 121 are evenly distributed along the circumference of the support tube 112, which can ensure the stability of the liquid inlet assembly 102 when it makes linear movement.

[0052] It should be noted that in some other possible implementations, see [link to relevant documentation]. Figure 23 As shown, the guide groove 122 may have a horizontal portion 123 and a vertical portion 124. The insertion cavity 107 has a stop block on its wall, and the atomizing core 103 has a stop groove. When the stop block is located in the stop groove, the liquid inlet assembly 102 can rotate together with the atomizing core 103 around the axis of the atomizing core 103. When the guide block 121 is located in the horizontal portion 123, the liquid inlet assembly 102 cannot descend, and the liquid inlet assembly 102 is in a disconnected state. The atomizing core 103 is first inserted into the insertion cavity 107 of the liquid inlet assembly 102, and then passes through the insertion cavity 107... The stop block on the wall of 7 restricts the insertion depth of the atomizing core 103 to ensure that the atomizing core 103 is connected to the first liquid inlet 108, and the stop block is limited to the stop groove; then the atomizing core 103 is rotated, and due to the cooperation between the stop block and the stop groove, the liquid inlet assembly 102 and the atomizing core 103 rotate together, so that the guide block 121 moves from the horizontal part 123 to the vertical part 124, and then the liquid inlet assembly 102 and the atomizing core 103 move together to the bottom of the mounting cavity 105, thereby realizing the liquid inlet assembly 102 switching from the disconnected state to the connected state.

[0053] Please return Figure 8As shown, in some embodiments, the atomizer 100 further includes an elastic element 125, which is used to disconnect the first liquid inlet hole 108 on the liquid inlet assembly 102 from the first liquid outlet hole 106. The elastic element 125 can keep the first liquid inlet hole 108 and the first liquid outlet hole 106 disconnected in the atomizer 100 when there is no atomizing core 103, effectively preventing accidental leakage of the aerosol matrix when not in use. This automatic cut-off mechanism improves the safety of using the atomizer 100. The elastic element 125, combined with the multiple protrusions (second protrusion 118, third protrusion 119) on the sealing sleeve 113, can further ensure the sealing effect when the first liquid inlet hole 108 and the first liquid outlet hole 106 are disconnected. For example, the elastic element 125 is located at the bottom of the mounting cavity 105. The elastic element 125 is a compression spring, which is sleeved on the support tube 112. When the liquid inlet assembly 102 switches from the disconnected state to the connected state, the support tube 112 can compress the elastic element 125. When the atomizing core 103 is pulled out, the liquid inlet assembly 102 can return to the disconnected state under the action of the elastic element 125.

[0054] See Figure 11 As shown, in some embodiments, the liquid inlet assembly 102 has a second guide slope 126, which is disposed around the opening of the insertion cavity 107. This guides the atomizing core 103 to automatically align with the center of the insertion cavity 107 during insertion, reducing insertion difficulties caused by angular deviations or improper operation, and making the insertion process of the atomizing core 103 smoother. For example, the second guide slope 126 can be a slope formed by chamfering the opening of the insertion cavity 107.

[0055] Combination Figure 4 and Figure 5 As shown, in some embodiments, the mounting cavity 105 includes a first sub-cavity 127 and a second sub-cavity 128. The diameter of the first sub-cavity 127 is smaller than the diameter of the second sub-cavity 128, and the liquid inlet assembly 102 is disposed in the second sub-cavity 128. The first sub-cavity 127 is used to guide the atomizing core 103 into the insertion cavity 107. The smaller diameter of the first sub-cavity 127 serves as a guide channel for the insertion of the atomizing core 103, ensuring that the atomizing core 103 can be accurately aligned and smoothly enter the insertion cavity 107. The larger diameter of the second sub-cavity 128 provides sufficient space for the installation and linear movement of the liquid inlet assembly 102, while also accommodating structures such as the elastic element 125. In addition, the smaller diameter of the first sub-cavity 127 also facilitates increasing the volume of the liquid storage cavity 104, thereby allowing the liquid storage cavity 104 to store more aerosol matrix.

[0056] Combination Figure 4 and Figure 5As shown, in some embodiments, the housing 101 includes an outer shell 129 and an inner support 130, with the outer shell 129 and the inner support 130 cooperating to form a liquid storage chamber 104. The separate arrangement of the outer shell 129 and the inner support 130 facilitates the manufacturing of the housing 101. For example, the outer shell 129 has an outer surface portion 131 and a first inner tube portion 132, which are fixedly connected. This fixed connection can be achieved by using an integral molding process to form an integral structure between the outer surface portion 131 and the first inner tube portion 132. The inner support 130 includes a first base portion 133 and a second inner tube portion 134, which are fixedly connected. This fixed connection can also be achieved by using an integral molding process to form an integral structure between the first base portion 133 and the second inner tube portion 134. The first base portion 133 is inserted into the outer surface portion 131. A sealing ring can be provided between the first base portion 133 and the outer surface portion 131 to improve the sealing performance of the connection between the two. The outer shell 129 also has a liquid injection hole 135, which communicates with the liquid storage chamber 104. The atomizer 100 also includes a liquid injection plug 136, which is detachably installed in the liquid injection hole 135. The aerosol matrix can be added to the liquid storage chamber 104 through the liquid injection hole 135.

[0057] Combination Figure 4 , Figure 5 , Figure 9 and Figure 10 As shown, in one embodiment, the atomizer 100 further includes a sealing ring 137, which is disposed on the first inner tube portion 132. The first inner tube portion 132 is inserted into the second inner tube portion 134. The sealing ring 137 is used to ensure the tightness of the connection between the two after the first inner tube portion 132 is inserted into the second inner tube portion 134. The sealing ring 137 can be made of silicone. The first inner tube portion 132 and the second inner tube portion 134 cooperate to form an installation cavity 105. The first inner tube portion 132 is used to form a first sub-cavity 127, and the second inner tube portion 134 is used to form a second sub-cavity 128. The sealing ring 137 can also limit the movement distance of the liquid inlet assembly 102 in the length direction of the atomizer 100 to ensure that when the liquid inlet assembly 102 is disconnected, the first liquid outlet 106 is located between the second protrusion 118 and the third protrusion 119.

[0058] Combination Figures 18 to 20As shown, in another embodiment, the first inner tube portion 132 is inserted into the second inner tube portion 134. A sealing ring can be provided between the first inner tube portion 132 and the second inner tube portion 134 to ensure the sealing of the connection between them. The inner support 130 also includes an extension tube portion 138, the diameter of which is smaller than the diameter of the second inner tube portion 134. Thus, the extension tube portion 138 is inserted into the first inner tube portion 132, and a guide groove 122 can be provided on the extension tube portion 138. The first inner tube portion 132 and the extension tube portion 138 cooperate to form an installation cavity 105. A portion of the liquid inlet assembly 102 extends into the cavity of the extension tube portion 138. The liquid inlet assembly 102 can move linearly in the first inner tube portion 132. The diameter of the cross-section of the cavity of the first inner tube portion 132 is equal everywhere along the length direction of the first inner tube portion 132.

[0059] Combination Figure 24 and Figure 25 As shown, in some embodiments, the atomizing core 103 has a second liquid inlet 139. The diameter of the second liquid inlet 139 can be smaller than the diameter of the first liquid inlet 108, which reduces the alignment requirements between the second liquid inlet 139 and the first liquid inlet 108. The number of first liquid inlets 108 is equal to the number of second liquid inlets 139. When the atomizing core 103 is inserted and the liquid inlet assembly 102 is in a connected state, the positions of the first liquid inlets 108 and the second liquid inlets 139 correspond. The second liquid inlets 139 are located between two adjacent fourth protrusions 120. The two fourth protrusions 120 can be press-fitted with the corresponding areas of the atomizing core 103, so that the aerosol matrix flowing out from the first liquid inlet 108 will not flow into non-designed areas, thus ensuring the sealing between the liquid inlet assembly 102 and the atomizing core 103 after insertion. For example, the number of second liquid inlets 139 can be 2, 3, or 4.

[0060] Combination Figures 24 to 26As shown, in some embodiments, the atomizing core 103 includes a shell 140, a heating element 141, and a first liquid-absorbing element 142. The first liquid-absorbing element 142 encloses the heating element 141, and both the first liquid-absorbing element 142 and the heating element 141 are installed in the cavity of the shell 140. This allows the shell 140 to provide support for the heating element 141 and the first liquid-absorbing element 142, reducing the possibility of deformation of the heating element 141 during insertion and removal. The first liquid-absorbing element 142 can continuously absorb aerosol matrix from the liquid storage cavity 104 and supply it to the heating element 141, reducing the possibility of the heating element 141 burning out. For example, the first liquid-absorbing element 142 can be made of polyester fiber, organic cotton, or silicone foam. The shell 140 can be made of metal, such as aluminum alloy, copper, or stainless steel, which can improve rigidity. The second liquid inlet 139 can be formed on the shell 140; the shell 140 can also have a second air inlet 143, with the second liquid inlet 139 close to the nozzle 111 and the second air inlet 143 away from the nozzle 111. There can be multiple second air inlets 143; for example, there can be two, three, or four second liquid inlets 139. The atomizing core 103 also includes a supporting inner tube 144 and a third liquid-absorbing element 145; the first liquid-absorbing element 142 wraps around the supporting inner tube 144, the third liquid-absorbing element 145 is located within the supporting inner tube 144, the third liquid-absorbing element 145 wraps around the heating element 141, and the third liquid-absorbing element 145 forms an airflow channel 146, which is connected to the second air inlet 143. The material of the third liquid-absorbing element 145 can be polyester fiber, organic cotton, or silicone foam. The inner support tube 144 has a third liquid inlet 147, through which the aerosol matrix flows from the second liquid inlet 139 to the first liquid suction element 142, then through the third liquid inlet 147 to the third liquid suction element 145, and finally through the third liquid suction element 145 to the heating element 141. The heating element 141 can be a heating mesh or a heating wire. When the heating element 141 is energized, it can atomize the liquid aerosol matrix, thereby forming an aerosol.

[0061] See Figure 25 As shown, in some embodiments, the atomizing core 103 further includes a conductive electrode 148, and the heating element 141 is electrically connected to the conductive electrode 148. The conductive electrode 148 is fixedly connected to the shell 140, thus ensuring electrical connection between the atomizing core 103 and the power supply assembly 200 to supply power to the heating element 141. The atomizing core 103 also includes an insulating ring 149. The atomizing core 103 has two conductive electrodes 148, one of which is annular and the other is columnar. The columnar conductive electrode 148 is inserted into the insulating ring 149, while the annular conductive electrode 148 is sleeved on the outside of the insulating ring 149. The annular conductive electrode 148 is insulated from the shell 140, for example, by using an insulating sleeve. The two conductive pins of the heating element 141 are electrically connected to the two conductive electrodes 148 respectively.

[0062] See Figure 27 As shown, in some embodiments, the nozzle 111 has a first channel 160, the inner wall of the first channel 160 has a first slot 150, and the outer surface of the atomizing core 103 has a first retaining platform 151, which is confined within the first slot 150. This ensures the stability of the connection between the nozzle 111 and the atomizing core 103, reducing the possibility of separation between the nozzle 111 and the atomizing core 103 during removal. The first channel 160 communicates with the cavity of the shell 140 and also with the airflow channel 146. For example, the nozzle 111 and the shell 140 of the atomizing core 103 can be integrated using an insert injection molding process.

[0063] In some embodiments, the nozzle 111 and the housing 101 may have a threaded structure (not shown). This threaded structure ensures that after the atomizing core 103 is engaged with the liquid inlet assembly 102, the liquid inlet assembly 102 will not return to the open state under the action of the elastic member 125. This also allows for a detachable connection between the atomizing core 103 and the nozzle 111 as a whole and the housing 101. For example, the nozzle 111 may have an external thread, while the housing 101 may have an internal thread that mates with the external thread.

[0064] See Figure 5 and Figure 12 As shown, in one embodiment, the end of the support tube 112 away from the nozzle 111 has a stop rib 152, which is located in the cavity of the support tube 112, i.e., in the insertion cavity 107. Since the nozzle 111 is threadedly connected to the housing 101, the nozzle 111 and the atomizing core 103 are prevented from moving along the length of the atomizer 100. When the atomizing core 103 abuts against the stop rib 152, the liquid inlet assembly 102 is blocked, and the elastic element 125 is compressed. Thus, after the atomizing core 103 and the liquid inlet assembly 102 are in contact, the liquid inlet assembly is always in a connected state.

[0065] See Figure 15 and Figure 24 As shown, in another embodiment, the outer surface of the housing 140 of the atomizing core 103 may have a limiting wing 153. When the atomizing core 103 is inserted into the cavity 107, the limiting wing 153 abuts against the top end of the liquid inlet assembly 102 (i.e. the end near the nozzle 111). In this way, after the atomizing core 103 and the liquid inlet assembly 102 are in contact, the liquid inlet assembly can be kept in a connected state.

[0066] Combination Figure 28 and Figure 29As shown, in some embodiments, one of the nozzle 111 and the housing 101 has a positioning groove 154, and the other of the nozzle 111 and the housing 101 has a positioning protrusion 155; when the positioning protrusion 155 is confined within the positioning groove 154, the first liquid inlet 108 communicates with the second liquid inlet 139. The cooperation between the positioning protrusion 155 and the positioning groove 154 can reduce the possibility of the process nozzle 111 rotating relative to the housing 101, and reduce the problem of poor liquid transfer caused by misalignment between the first liquid inlet 108 and the second liquid inlet 139. For example, the positioning protrusion 155 is provided on the housing 101, while the positioning groove 154 is provided on the nozzle 111.

[0067] Combination Figure 28 and Figure 29 As shown, in some embodiments, the nozzle 111 has a first guide slope 156, the length of which extends circumferentially along the nozzle 111; a positioning protrusion 155 or a positioning groove 154 is disposed on the first guide slope 156. The first guide slope 156 extends circumferentially along the nozzle 111, forming a continuous inclined surface, which guides the positioning protrusion 155 into the positioning groove 154 when the nozzle 111 and the atomizing core 103 are inserted into the housing 101, thereby limiting the positioning between the positioning protrusion 155 and the positioning groove 154, ensuring communication between the second liquid inlet hole 139 and the first liquid inlet hole 108 of the atomizing core 103, and avoiding poor liquid transmission due to installation deviation. For example, the positioning groove 154 is located on the first guide slope 156. The housing 101 may also have an open indicator and a close indicator, and the mouthpiece 111 may have an arrow indicator (not shown). When the arrow indicates the open indicator, the mouthpiece 111 is unlocked from the housing 101, and the atomizing core 103 is also unlocked from the housing 101. At this time, the atomizing core 103 can be pulled out from the liquid inlet assembly 102. When the arrow indicates the close indicator, the mouthpiece 111 is locked from the housing 101, and the atomizing core 103 is also locked from the housing 101. At this time, the atomizing core 103 cannot be pulled out from the liquid inlet assembly 102. In this case, the elastic element 125 is compressed, the liquid inlet assembly 102 is connected, and the second liquid inlet hole 139 on the atomizing core 103 is connected to the first liquid inlet hole 108.

[0068] See Figure 13As shown, in some embodiments, the bottom of the mounting cavity 105 has a first air inlet 157, and the power supply assembly 200 includes a second liquid-absorbing member 159, which is disposed opposite to the first air inlet 157. The second liquid-absorbing member 159 can absorb aerosol matrix that may leak out during the replacement of the atomizing core 103, or other liquids generated during use, thereby ensuring the safety of the power supply assembly 200. The material of the second liquid-absorbing member 159 can be polyester fiber, organic cotton, or silicone foam.

[0069] See Figure 1 , Figure 14 and Figure 30 As shown, in some embodiments, the power supply assembly 200 includes a battery 202, a power supply electrode 203, a printed circuit board assembly (PCBA) 204, and a power supply box 205. The power supply electrode 203 is electrically connected to the PCBA 204, and the battery 202 is also electrically connected to the PCBA 204. The battery 202, power supply electrode 203, and PCBA 204 are housed in the power supply box 205. The housing 101 of the atomizer 100 is connected to the power supply box 205. An airflow sensor (or microphone) may also be integrated on the PCBA 204 to activate the atomizing core 103 of the atomizer 100, which then heats the aerosol matrix stored in the atomizer 100, converting the aerosol matrix into an aerosol. The airflow sensor can be protected by a silicone sleeve 206. The second liquid suction element 159 is installed in the power supply box 205. The bottom of the power supply box 205 has a third air inlet 207, so that when the user draws through the nozzle 111, the outside air can enter the interior of the atomizing core 103 in sequence through the third air inlet 207, the first air inlet 157 and the second air inlet 143.
