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

The matrix storage module stores the atomizing matrix, and the atomization module is connected to the matrix storage module to atomize the atomized matrix within it. The control module is connected to the atomization module to control its operation.

[0003] During use, the internal environment of atomizers and e-vaporizers is relatively enclosed, making it easy for heat to accumulate inside. Therefore, when atomizers and e-vaporizers are used for extended periods, the outer surface of the casing can easily become hot. This is especially true for atomizers and e-vaporizers that use heating to achieve atomization; excessively high temperatures on the outer casing can even burn the user, thus reducing their vaping experience. Summary of the Invention

[0004] In view of this, the present invention provides an atomizer and an electronic atomizing device. By setting a heat dissipation bracket in the air passage, the airflow entering the housing guides the heat on the heat dissipation bracket to the atomizing module to cool the inside of the housing, thus solving the technical problem of excessively high external temperature of the housing and poor atomization experience caused by the relatively closed housing structure in the prior art.

[0005] To address the aforementioned problems, according to one aspect of this application, the present invention provides an atomizer comprising:

[0006] The outer casing has an air inlet, an air outlet, and an air passage that communicates with the air inlet and the air outlet.

[0007] The atomizing module, located inside the housing, is used to generate aerosols.

[0008] The control module is located inside the housing and is connected to the atomizing module;

[0009] A heat dissipation bracket extends from the air inlet to the air outlet and is positioned close to the air duct. It is used to transfer heat from inside the housing to the airflow within the air duct to cool the housing. In some embodiments, one end of the heat dissipation bracket is connected to the atomizing module, and the other end is connected to the control module. A chamber communicating with the air duct is located in the middle of the heat dissipation bracket.

[0010] In some embodiments, the atomizer includes a first support member disposed at one end of a heat dissipation bracket. The first support member has a first groove for mounting an atomizing module and a second groove located on the periphery of the first groove.

[0011] In some embodiments, a first air passage is provided between the inner wall of one end of the heat dissipation bracket and the outer wall of the first support member, and a second air passage is provided between the outer wall of the other end of the heat dissipation bracket and the inner wall of the outer shell. The first air passage is connected to the second air passage through a chamber to form an air passage.

[0012] In some embodiments, the atomizer further includes a second support member disposed in the first groove, the second support member being used to form an atomization channel, the outer wall of the second support member and the inner wall of the first groove forming a third air passage segment, one end of the third air passage segment being connected to the first air passage segment, and the other end of the third air passage segment being connected to the air outlet.

[0013] In some embodiments, the atomizing module includes a heating element connected to the control module;

[0014] A flow guiding module is installed inside the chamber. The flow guiding module is electrically connected to the heating core and is used to guide the gas in the airway.

[0015] In some embodiments, the flow guiding module includes a micro motor and a fan blade connected to the micro motor, and the heating core is electrically connected to the micro motor to drive the fan blade to rotate.

[0016] In some embodiments, the bottom of the first support member is provided with a snap-fit ​​portion for fixing the atomizing module.

[0017] In some embodiments, the control module includes a circuit board disposed along the direction in which the heat sink extends.

[0018] To address the aforementioned problems, according to one aspect of this application, the present invention provides an electronic atomizing device, which includes the aforementioned atomizer.

[0019] Compared with the prior art, the atomizer of the present invention has at least the following beneficial effects:

[0020] The atomizer provided in this embodiment is used to generate an aerosol that can be inhaled by a user from an atomizing matrix. The air duct guides the airflow into the housing and the generated aerosol. The atomizing module is disposed within the housing to generate an aerosol from the atomizing matrix within the housing. The control module is disposed within the housing and connected to the atomizing module to control its operation. However, during use, due to the relatively enclosed structure of the housing, and the gradual increase in temperature inside the housing due to prolonged use of the atomizing module and control module, the user faces a risk of burns while holding the atomizer. Furthermore, the high temperature of the housing degrades the user's atomization experience. A heat dissipation bracket is disposed within the housing to improve the heat dissipation efficiency of the internal modules. The heat dissipation bracket extends from the air inlet and outlet of the housing to increase the heat dissipation area and improve efficiency. Additionally, the heat dissipation bracket is positioned close to the housing to guide heat into the airflow within the air duct, and through this airflow, transfers some of the heat to the atomizing module to improve the atomization effect. This invention solves the technical problem of excessively high external temperature and poor atomization experience caused by the relatively closed shell structure in the prior art, by setting a heat dissipation bracket in the air duct, so that the airflow entering the shell can guide the heat on the heat dissipation bracket to the atomization module to cool the inside of the shell.

[0021] On the other hand, the electronic atomizing device provided by the present invention is designed based on the above-mentioned atomizer, and its beneficial effects are all described in the above-mentioned atomizer, and will not be repeated here.

[0037] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly.

[0038] Example 1

[0039] This invention provides an atomizer, see reference. Figures 1 to 9 The atomizer includes a housing 1, an atomizing module 2, a control module 3, and a heat dissipation bracket 4. The housing 1 has an air inlet 11, an air outlet 12, and an air passage 5 communicating with the air inlet 11 and the air outlet 12. The atomizing module 2 is disposed inside the housing 1 and is used to generate aerosol. The control module 3 is disposed inside the housing 1 and connected to the atomizing module 2. The heat dissipation bracket 4 extends from the air inlet 11 to the air outlet 12 and is positioned close to the air passage, used to transfer heat from inside the housing to the airflow within the air passage to cool the housing.

[0040] Specifically, the atomizer provided in this embodiment is used to generate an aerosol that can be inhaled by a user from an atomizing matrix. The air duct 5 guides the airflow into the outer shell 1 and the generated aerosol. The atomizing module 2 is disposed within the outer shell 1 to generate an aerosol from the atomizing matrix within the outer shell 1. The control module 3 is disposed within the outer shell 1 and is connected to the atomizing module 2 to control its operation. However, during use, due to the relatively enclosed structure of the outer shell 1, and the gradual increase in temperature inside the outer shell 1 due to prolonged use of the atomizing module 2 and the control module 3, the user faces a risk of burns while holding the atomizer. Furthermore, the high temperature of the outer shell 1 degrades the user's atomization experience. A heat dissipation bracket 4 is disposed within the outer shell 1 to improve the heat dissipation efficiency of the internal modules. The heat dissipation bracket 4 extends from the air inlet 11 and air outlet 12 of the outer shell 1 to increase the heat dissipation area within the outer shell 1 and improve heat dissipation efficiency. In addition, the heat dissipation bracket 4 is located near the outer shell 1 to guide heat into the airflow in the air passage 5, and through the airflow, transfer part of the heat to the atomizing module 2 to improve the atomization effect.

[0041] It should be noted that the air inlet 11 and the air outlet 12 are located on the outer wall of the outer casing 1. The air inlet 11 can be located on the bottom wall, side wall, or top wall of the outer casing 1, and similarly, the air outlet 12 can be located on the bottom wall, side wall, or top wall of the outer casing 1. To improve heat dissipation efficiency, the air inlet 11 is located at the bottom of the outer casing 1, and the air outlet 12 is located at the top of the outer casing 1, so that the air passage 5 is longer. This structure can reduce the speed at which heat is transferred from inside the outer casing 1 to the outside, and the airflow in the air passage 5 can absorb more of the heat lost from inside the outer casing 1 and bring the heat back to the vicinity of the atomizing module 2 to improve the atomization effect.

[0042] The atomizing module 2 includes a heating core and pins connected to the heating core. The heating core is connected to the control module 3 via the pins to generate heat, which in turn heats the atomizing matrix inside the housing 1. It should be noted that an independent atomizing matrix storage module can be set inside the housing 1 to store the atomizing matrix. Of course, the heating core can also be directly connected to the liquid storage cotton filled with the atomizing matrix to achieve atomization.

[0043] An air passage 5 (not shown in the figure) is provided on the inner wall of the outer casing 1, or an air passage 5 is formed between the inner wall of the outer casing 1 and the outer wall of the heat dissipation bracket 4 (see reference). Figure 3 and Figure 4 ).

[0044] The control module 3 includes a micro circuit board and a pneumatic switch and a power switch electrically connected to the micro circuit board. The pneumatic switch is connected to the air passage 5 and is used to control the operation of the heating element through airflow. The power button is movably set on the outer casing 1 and is used to control the on / off state of the micro circuit board circuit.

[0045] The heat dissipation bracket 4 is used to fix the atomizing module 2, the control module 3, and the matrix storage module. The shape of the heat dissipation bracket 4 can be adjusted to adapt to the structure of these modules. Furthermore, the heat dissipation bracket 4 conducts heat from inside the outer casing 1 to itself, and simultaneously transfers the carried heat to the airflow in the cooler air passage 5 through its large surface area. (Reference) Figure 8 The heat dissipation bracket 4 has an overall cylindrical structure that matches the height and shape of the outer shell 1. The cylindrical structure has a square first heat dissipation hole and a square second heat dissipation hole that match the height of the control module 3. The first and second heat dissipation holes are positioned opposite each other to facilitate airflow within the cylindrical structure, preventing poor heat dissipation caused by a closed internal structure. The heat dissipation bracket 4 also has a limiting structure for fixing the atomization module 2, the control module 3, and the matrix storage module. (Refer to...) Figures 3 to 5 as well as Figure 8 The limiting structure is a limiting block. The heat dissipation bracket 4 can be made of materials such as copper or iron, which have supporting and heat-conducting functions.

[0046] In a specific embodiment, reference is made to... Figures 3 to 7 One end of the heat dissipation bracket 4 is connected to the atomizing module 2, and the other end of the heat dissipation bracket 4 is connected to the control module 3. The middle part of the heat dissipation bracket 4 is provided with a chamber 41 that communicates with the air passage 5.

[0047] Specifically, when the distance between the air inlet 11 and the air outlet 12 of the outer casing 1 is too far, it can easily lead to excessive suction resistance at the air outlet 12, making it difficult for airflow outside the outer casing 1 to enter the air passage 5. A chamber 41 is provided between the atomizing module 2 and the control module 3. On the one hand, this increases the radial cross-sectional width of the air passage 5 to reduce suction resistance; on the other hand, it can turbulentize the high-speed airflow within the air passage 5, achieving noise reduction.

[0048] It should be noted that the side of the heat dissipation bracket 4 closest to the atomizing module 2 can be a relatively enclosed structure to form chamber 41. For example, the heat dissipation bracket 4 can be... Figure 7 and Figure 8 In the intermediate structure, the end of the heat dissipation bracket 4 near the atomizing module 2 is a cylindrical structure, while the end near the control module 3 is a frame structure. The frame structure increases the contact area between the control module 3 and the airflow, thereby improving the cooling efficiency of the control module 3. In a specific embodiment, refer to... Figures 3 to 5 The atomizer includes a first support member 6 disposed at one end of the heat dissipation bracket 4. The first support member 6 is provided with a first groove 61 for installing the atomizing module 2. The first support member 6 is also provided with a second groove 62, which is located around the first groove 61.

[0049] Specifically, the first support member 6 is used to fix and support the atomizing module 2, wherein the first groove 61 on the first support member 6 is used to prevent the atomizing module 2 from being exposed. The second groove 62 is disposed on the periphery of the first groove 61 to form a heat insulation layer, which is used to prevent the temperature of the atomizing module 2 in the first groove 61 from being too fast, resulting in excessively high temperature on the outside of the outer shell 1 and high energy consumption of the atomizing module 2.

[0050] It should be noted that the first groove 61 can be a columnar structure or an annular structure. When the first groove 61 is a columnar structure, multiple columnar first grooves 61 are provided, and the multiple first grooves 61 are arranged circumferentially along the second groove 62. When the first groove 61 is an annular structure, the annular first groove 61 extends circumferentially along the second groove 61. In addition, the opening end of the first groove 61 faces the chamber 41. After part of the airflow enters the first groove 61 from the chamber 41, it forms a heat-insulating air layer. On the one hand, it prevents the heat of the atomizing module 2 from being transferred to the outside of the outer shell 1, resulting in a high temperature on the outside of the outer shell 1. On the other hand, it prevents excessive heat loss from the inside of the atomizing module 2, thereby reducing the atomization effect. The opening end of the second groove 62 faces the top of the outer shell 1 and is connected to the air passage 5.

[0051] In a specific embodiment, refer to 3 to 3. Figure 5 A first air passage section 51 is provided between the inner wall of one end of the heat dissipation bracket 4 and the outer wall of the first support member 6, and a second air passage section 52 is provided between the outer wall of the other end of the heat dissipation bracket 4 and the inner wall of the outer shell 1. The first air passage section 51 is connected to the second air passage section 52 through the chamber 41 to form an air passage 5.

[0052] Specifically, one end of the second airway section 52 is connected to the air inlet 11, and the other end of the second airway section 52 is connected to the inlet of the chamber 41, so as to guide the airflow outside the outer shell 1 into the chamber 41. At the same time, the airflow guides the heat on the control module 3 into the chamber 41 during the process of flowing through the second airway section 52. One end of the first airway section 51 is connected to the outlet of the chamber 41, and the other end of the first airway section 51 flows through the atomizing module 2 and then connects to the air outlet 12, so as to guide the airflow to the heating core of the atomizing module 2 and guide the aerosol at the heating core to the air outlet 12. At the same time, the airflow guides the heat in the chamber 41 to the heating core when it passes through the first airway section 51. Compared with the prior art, the temperature required for heating the heating core is relatively low at this time. Therefore, the atomizer provided in this embodiment is more energy-efficient.

[0053] In the specific embodiments, please continue to refer to Figures 3 to 5 The atomizer also includes a second support member 7 disposed in the first groove 61. The second support member 7 is used to form an atomization channel. The outer wall of the second support member 7 and the inner wall of the first groove 61 form a third air passage section 53. One end of the third air passage section 53 is connected to the first air passage section 51, and the other end of the third air passage section 53 is connected to the air outlet 12.

[0054] Specifically, the first groove 61 is used to fix the atomizing module 2 within the first groove 61, and the first groove 61 forms an atomizing channel for accommodating the heating core of the atomizing module 2. The atomizing channel is connected to the air passage 5 and the air outlet 12. The third air passage section 53 is connected to the first air passage section 51 and the air outlet 12 for guiding the airflow. The outer wall of the second support member 7 and the inner wall of the first groove 61 form the third air passage section 53 so that the third air passage section 53 is located on the periphery of the first groove 61 to form a new heat insulation layer.

[0055] It should be noted that the second air passage section 52 and the third air passage section 53 are arranged parallel to each other in the height direction of the outer shell 1 to keep the atomizing module 2 warm and prevent the external temperature of the outer shell 1 from being too high.

[0056] In a specific embodiment, the atomizing module 2 includes a heating element connected to the control module 3;

[0057] A flow guiding module 8 is installed inside the chamber 41. The flow guiding module 8 is electrically connected to the heating core and is used to guide the gas in the airway 5.

[0058] Specifically, the heating core is used to heat the nearby atomizing matrix to generate an aerosol. The heating core is made of a resistive material, including materials such as gold and copper that can conduct heat. The flow guiding module 8 is located within the chamber 41 to improve the flow of gas within the airway 5. This improves atomization efficiency and cools the outer shell 1 by accelerating gas flow. The flow guiding module 8 is connected to the heating core to conduct current within it. More specifically, the flow guiding module 8 has a first state and a second state. When the temperature inside the outer shell 1 rises, the temperature inside the heating core also rises, and the resistance of the heating core decreases. At this time, the circuit of the flow guiding module 8 is activated, and the flow guiding module 8 accelerates the airflow within the airway 5; in this state, the flow guiding module 8 is in the first state. When the temperature inside the outer shell 1 is low, the temperature inside the heating core also decreases, and the resistance of the heating core increases. At this time, the circuit of the flow guiding module 8 is deactivated, and the flow guiding module 8 does not work; in this state, the flow guiding module 8 is in the second state. Compared to atomizers in the prior art, the atomizer of this embodiment can automatically regulate the temperature inside the outer shell 1 without requiring complex control programs.

[0059] In a specific embodiment, reference is made to... Figure 4 The flow guiding module 8 includes a micro motor 81 and a fan blade 82 connected to the micro motor 81. The heating core is electrically connected to the micro motor 81 to drive the fan blade 82 to rotate.

[0060] Specifically, the power input terminal of the micro motor 81 in the airflow guiding module 8 is electrically connected to the heating core, and the fan blade 82 is connected to the power output terminal of the micro motor 81 to drive the fan blade 82 to rotate, thereby guiding the airflow. It should be noted that the micro motor 81 can also guide the airflow in the first groove 61 by rotating forward and reverse. More specifically, the micro motor 81 drives the fan blade 82 to rotate forward, so as to guide the airflow in the second air passage section 52 and the chamber 41 to the first air passage section 51; after the micro motor 81 rotates for a certain period of time, it drives the fan blade 82 to rotate in reverse, so as to guide the gas in the first groove 61 to the chamber 41, and then to the atomizing module 2 through the first air passage section 51, thereby preventing the technical problem of poor cooling efficiency of the outer shell 1 due to excessively high temperature in the first groove 61.

[0061] In a specific embodiment, reference is made to... Figures 3 to 5 , Figure 7 as well as Figure 9 The bottom of the first support member 6 is provided with a snap-fit ​​part 63 for fixing the atomizing module 2.

[0062] Specifically, the latching part 63 is used to latch the bottom of the atomizing module 2 to prevent the atomizing module 2 from falling into the chamber 41. In addition, when the atomizer is provided with a flow guiding module 8, the flow guiding module 8 can be fixed to the latching part 63. For example, when the flow guiding module 8 is a micro motor 81 and a fan blade 82, the micro motor 81 can be fixed at the latching part 63 or fixed in the second groove 62, and the fan blade 82 is rotatably connected to the latching part 63 through a bearing.

[0063] It should be noted that, as Figure 9 As shown, the snap-fit ​​part 63 includes an annular structure disposed at the bottom of the first support member 6 and a limiting block disposed at the bottom of the annular structure. The inner ring of the bearing is sleeved on the outside of the annular structure, and the middle part of the fan blade 82 is sleeved on the outer ring of the bearing to achieve a rotatable connection.

[0064] In a specific embodiment, refer to 1 Figures 5 to 7 The control module 3 includes a circuit board, which is arranged along the direction of the heat sink bracket 4.

[0065] Specifically, the circuit board is arranged along the extension direction of the heat sink 4 to increase the heat conduction area between the circuit board and the heat sink 4, thereby improving heat dissipation efficiency. In addition, to prevent the heat sink 4 from interfering with the current of the circuit board, an insulating layer can be coated on the outside of the circuit board.
