According to the atomizer, the containing cavity is arranged to be communicated between the air inlet channel and the atomization channel, so that the air inlet channel and the atomization channel are communicated in an open mode, and therefore it can be avoided that aerosol matrixes or condensate leaked out of the atomization channel directly enters the air inlet channel; furthermore, airflow enters the air inlet channel in the first direction parallel to the axial direction of the atomization channel, and the airflow leaves the airflow channel from the air outlet end deviating from the atomization channel or parallel to the axial direction of the atomization channel so as to enter the containing cavity. Therefore, the end face of the air outlet end does not face the atomization assembly, aerosol matrixes or condensate dripping in the atomization channel or the containing cavity does not fall into the air inlet channel from the air outlet end, and the aerosol matrixes or the condensate is further prevented from leaking to the outside of the atomizer through the air inlet channel.

[0044] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0047] See also Figure 1-3 As shown, the present application provides an atomizer 100, which includes a main body and an atomizer assembly 80. The atomizer assembly 80 is arranged in the main body and is constructed to form an atomization channel 81. The main body is constructed to form an air inlet channel 225 and a accommodating chamber 13. The accommodating chamber 13 is connected between the air inlet channel 225 and the atomization channel 81.

[0048] The accommodating chamber 13 is arranged to be connected between the air inlet channel 225 and the atomization channel 81, so that the air inlet channel 225 and the atomization channel 81 are in an open connection state within the main body, that is, the air inlet channel 225 and the atomization channel 81 are not directly connected, or are connected through a pipeline, thereby preventing the aerosol matrix or condensate leaked from the atomization channel 81 from directly entering the air inlet channel 225, thereby reducing the risk of the aerosol matrix and condensate leaking from the air inlet channel 225 to the outside of the nebulizer 100.

[0049] Furthermore, the air inlet channel 225 has an air inlet end 226 and an air outlet end 227. The airflow enters the air inlet channel 225 from the air inlet end 226 along a first direction, enters the accommodating chamber 13 from the air outlet end 227, and then enters the atomization channel 81 from the accommodating chamber 13, and leaves the atomizer 100 after mixing with the generated aerosol in the atomization channel 81.

[0050] The first direction is a direction perpendicular to the orthographic projection of the end face of the air inlet end 226, and the first direction is parallel to the axial direction of the atomization channel 81, so that when the atomizer 100 is in use, the air inlet end 226 is located at the bottom of the atomizer 100, thereby preventing the user from blocking the air inlet end 226 when holding the atomizer 100, thereby preventing the inhalation resistance from increasing.

[0051] The end surface of the gas outlet 227 faces away from the atomizing channel 81, so that the airflow flowing out of the gas inlet channel 225 and entering the accommodating chamber 13 enters the accommodating chamber 13 in the direction toward the gas inlet end 226, thereby preventing the aerosol matrix or condensate dripping from the atomizing channel 81 from directly falling from the gas outlet 227 into the gas inlet channel 225, and the condensate dripping in the accommodating chamber 13 will not fall from the gas outlet 227 into the gas inlet channel 225 and leak from the gas inlet end 226 to the outside of the atomizer 100. Therefore, the aerosol matrix or condensate is further prevented from leaking to the outside of the atomizer 100 through the gas inlet channel 225.

[0052] Alternatively, the end surface of the gas outlet end 227 is parallel to the axial direction of the atomizing channel 81, so that the end surface of the gas outlet end 227 is neither facing the atomizing channel 81 nor away from the atomizing channel 81, thereby preventing the aerosol matrix or condensed liquid dripping from the atomizing channel 81 from directly falling from the gas outlet end 227 into the gas inlet channel 225, and the condensed liquid dripping from the accommodating cavity 13 will not fall from the gas outlet end 227 into the gas inlet channel 225 and leak from the gas inlet end 226 to the outside of the atomizer 100. Therefore, the aerosol matrix or condensed liquid is further prevented from leaking to the outside of the atomizer 100 through the gas inlet channel 225.

[0053] For further information, see Figure 3-5 As shown, the main body includes a shell 10, and the shell 10 is constructed to have an air inlet hole 121 and the accommodating cavity 13. The air inlet hole 121 is connected to the accommodating cavity 13, and one end of the air inlet hole 121 away from the accommodating cavity 13 defines the air inlet end 226, so that external gas enters the interior of the atomizer 100 from the air inlet hole 121.

[0054] The main body further includes an airflow redirecting member 20 , which is in communication with the air inlet hole 121 and defines the air inlet passage 225 together with the air inlet hole 121 .

[0055] Furthermore, the airflow diverting member 20 includes a first section 21 and a second section 22, the first section 21 is connected between the second section 22 and the air inlet hole 121, and the end of the second section 22 away from the first section 21 defines the air outlet end 227, so that the external airflow enters from the air inlet hole 121 and flows out from the end of the second section 22 away from the first section 21 and enters the accommodating cavity 13.

[0056] The flow direction of the airflow in the first section 21 is different from the flow direction in the second section 22, so that after the airflow enters the air inlet 121 along the first direction, it will flow out of the airflow diverter 20 from the second direction. The second direction is perpendicular to the first direction, so that the air outlet end 227 is neither facing the atomizer assembly 80 nor away from the atomizer assembly 80; or, the angle between the second direction and the first direction is an acute angle, so that the air outlet end 227 is away from the atomizer assembly 80.

[0057] Furthermore, the airflow redirecting member 20 can be made of plastic or metal, which is not limited here. By providing the independent airflow redirecting member 20, the movement direction of the airflow before entering the accommodating chamber 13 can be adjusted, so that the structure for changing the airflow direction is simple and easy to assemble with the housing 10.

[0058] Furthermore, the first section 21 and the second section 22 are perpendicular to each other, so that the airflow enters the accommodating cavity 13 along the second direction perpendicular to the first direction, and the airflow moves along a straight line in the first section 21 and the second section 22, respectively, so as to facilitate the processing and manufacturing of the airflow diverting member 20, and one of the first section 21 and the second section 22 can be connected to the air inlet 121 at will.

[0059] The connection between the first section 21 and the second section 22 may be a right angle, or may be an oblique angle, a rounded angle, or an arc, so that the airflow can flow smoothly from the first section 21 into the second section 22 .

[0060] Alternatively, the angle between the first section 21 and the second section 22 is less than 90 degrees. Thus, the airflow enters the accommodating chamber 13 along the second direction whose angle with the first direction is an acute angle. The airflow moves along a straight line in the first section 21 and the second section 22 respectively, and returns to enter the accommodating chamber 13 at the connection between the first section 21 and the second section 22, and the air outlet end 227 is lower than the connection between the first section 21 and the second section 22. Therefore, even if the aerosol matrix or condensed liquid enters the second section 22 from the air outlet end 227, it can be prevented from directly entering the first section 21 and then leaking to the outside of the atomizer 100.

[0061] Alternatively, the first section 21 extends along the first direction, and the second section 22 extends along a curve, so that the gas outlet end 227 is away from the atomization assembly 80 , preventing the aerosol matrix or condensate in the atomization channel 81 and the accommodating chamber 13 from directly dripping into the gas inlet channel 225 .

[0062] For further information, see Figure 1-3 As shown, the housing 10 includes a first shell 11 and a second shell 16 connected to each other. The first shell 11 is structured to form a connecting pipe portion 12, and the connecting pipe portion 12 at least partially extends toward the accommodating chamber 13 along an axial direction parallel to the atomizing channel 81, and the connecting pipe portion 12 is structured to form the air inlet hole 121, the first section 21 is connected to the connecting pipe portion 12, and the second shell 16 is structured to form a nozzle 17, the nozzle 17 is located at one end of the second shell 16 away from the air inlet hole 121, and the end of the atomizing channel 81 away from the accommodating chamber 13 is connected to the nozzle 17, so that the generated aerosol is mixed with the airflow and leaves the atomizer 100 from the nozzle 17.

[0063] By arranging the connecting tube portion 12 to extend toward the accommodating cavity 13 along the axial direction of the atomizing channel 81, so that the air inlet hole 121 protrudes from the corresponding inner bottom wall 161 of the second shell 16, it is convenient to connect the airflow deflecting member 20 with the connecting tube portion 12, thereby reducing the difficulty of assembly and improving the assembly efficiency. At the same time, it can also prevent the aerosol matrix or condensate dripping onto the inner bottom wall 161 from leaking from the air inlet hole 121.

[0064] Furthermore, the main body further comprises a mounting seat 30, and the mounting seat 30 is sealed and connected between the first shell 11 and the second shell 16, so that the first shell 11 is separated from the second shell 16. The accommodating chamber 13 is defined between the mounting seat 30 and the first shell 11, the atomizing assembly 80 is connected between the nozzle 17 and the mounting seat 30, and a liquid storage chamber 70 is defined and formed between the mounting seat 30, the second shell 16 and the atomizing assembly 80. The liquid storage chamber 70 is used to contain an aerosol matrix.

[0065] For further information, see Figure 3 , Figure 6-7 As shown, the main body also includes a first sealing member 40 and a liquid locking member 60. The first sealing member 40 is sealingly connected between the first shell 11 and the mounting seat 30, and defines the accommodating cavity 13 with the first shell 11. The liquid locking member 60 is arranged in the accommodating cavity 13 to lock the aerosol matrix or condensate leaked from the atomization channel 81 into the accommodating cavity 13.

[0066] Furthermore, the first sealing member 40 is structured to form an air guiding channel 41 , and the air guiding channel 41 connects the accommodating cavity 13 and the atomizing channel 81 , so as to allow the gas in the accommodating cavity 13 to enter the atomizing channel 81 .

[0067] One end of the air guiding channel 41 away from the atomizing channel 81 is directly opposite to the liquid locking component 60, so that the aerosol matrix or condensed liquid dripping from the atomizing channel 81 to the air guiding channel 41 and from the air guiding channel 41 will directly fall onto the liquid locking component 60 and be directly locked by the liquid locking component 60, or the aerosol matrix or condensed liquid dripping from the atomizing channel 81 directly through the air guiding channel 41 to the liquid locking component 60 will be directly locked by the liquid locking component 60, thereby preventing the condensed liquid or aerosol matrix from dripping directly onto the airflow deflecting component 20, or dripping onto the inner bottom wall 161, thereby achieving effective interception of the aerosol or condensed liquid.

[0068] Furthermore, the liquid locking member 60 may be made of cotton material, such as cotton or sponge.

[0069] Furthermore, an air guiding space 14 is formed between the liquid locking component 60 and the inner wall of the first shell 11, and the air guiding space 14 is a part of the accommodating cavity 13, and the air guiding space 14 is staggeredly connected to the air guiding channel 41 and the air inlet channel 225, respectively, so that the air flow enters the air guiding space 14 from the air outlet end 227 to pass through the liquid locking component 60 and enter the air guiding channel 41, and the aerosol matrix or condensate dripping from the air guiding channel 41 will not fall into the air guiding space 14, and the condensate or aerosol matrix in the air guiding space 14 will not fall into the air inlet channel 225.

[0070] By providing the liquid locking member 60 and the air guiding space 14 , the aerosol matrix and the condensate are intercepted and locked, and it is also ensured that the airflow can smoothly pass through the liquid locking member 60 and enter the air guiding channel 41 .

[0071] Furthermore, the liquid locking member 60 is arranged at a certain distance from the first sealing member 40 so that the air flow in the air guiding space 14 can smoothly enter the air guiding channel 41 .

[0072] Further, the air guide channel 41 includes a first sub-channel 42 and a second sub-channel 44 that are interconnected, an end of the second sub-channel 44 away from the first sub-channel 42 is connected to the atomization channel 81, and an end of the first sub-channel 42 away from the second sub-channel 44 is connected to the air guide space 14. That is, the external airflow will sequentially pass through the air inlet channel 225, the air guide space 14, the first sub-channel 42, the second sub-channel 44, the atomization channel 81 and the suction nozzle 17.

[0073] The first sealing member 40 is formed with a first liquid collecting groove 43 corresponding to the second sub-channel 44, and the opening of the first liquid collecting groove 43 faces the atomization channel 81. By providing the first liquid collecting groove 43, the aerosol matrix leaked from the atomization channel 81 or the dripping condensate can be effectively collected, so that the aerosol matrix or the condensate is intercepted before the liquid locking member 60.

[0074] Furthermore, the aperture of the first sub-channel 42 gradually becomes smaller along the direction toward the second sub-channel 44, so that the first sub-channel 42 is a variable diameter hole toward the second sub-channel 44, so that the airflow entering the first sub-channel 42 through the air guide space 14 can be quickly converged in the first sub-channel 42, thereby increasing the flow rate of the airflow, thereby improving the user's experience when smoking.

[0075] In addition, the first sub-channel 42 with a variable diameter hole structure can also increase the projected area between the first sub-channel 42 and the opposite liquid lock component 60, so that the aerosol matrix or condensed liquid flowing along the inner wall of the first sub-channel 42 to the end of the first sub-channel 42 close to the liquid lock component 60 can fall onto the liquid lock component 60 in a relatively dispersed manner, avoiding the aerosol matrix or condensed liquid from falling too concentratedly on the same position of the liquid lock component 60.

[0076] Furthermore, a guide portion 45 is formed on one side of the first sealing member 40 close to the atomization channel 81 , and the guide portion 45 is used to intercept the aerosol matrix or condensate dripping from the atomization channel 81 and guide the intercepted aerosol matrix or condensate into the first liquid collecting tank 43 .

[0077] For further information, see Figure 6-7 As shown, the guide portion 45 includes a plurality of guide grooves 451 and air holes 452. The orthographic projection of the atomization assembly 80 along the axial direction of the atomization channel 81 is at least partially projected onto the guide portion 45, so that the aerosol matrix or condensate dripping from the atomization channel 81 to the guide grooves 451 will be guided by the guide grooves 451 and gathered into the first liquid collecting tank 43. The air holes 452 are located between adjacent guide grooves 451 and connected between the second sub-channel 44 and the atomization channel 81, so as to allow the airflow in the second sub-channel 44 to pass through and enter the atomization channel 81.

[0078] Furthermore, the main body further includes a second sealing member 50 , and the second sealing member 50 is sealingly connected between the mounting seat 30 and the second shell 16 .

[0079] Among them, see Figure 2-3As shown, the atomizer assembly 80 includes an atomizer tube 82 and an atomizer core 83. The atomizer core 83 is disposed in the atomizer tube 82. The opposite ends of the atomizer tube 82 are respectively sealed and connected between the suction nozzle 17 and the first sealing member 40, so that the second sealing member 50, the mounting seat 30, the second shell 16 and the atomizer tube 82 define the liquid storage chamber 70.

[0080] Furthermore, the atomizer tube 82 is structured to form at least one first liquid guide hole 821, the atomizer core 83 includes a mounting tube 831, a first liquid guide member 832, a second liquid guide member 833 and a heating member 834, the mounting tube 831 is structured to form at least one second liquid guide hole 8311, the first liquid guide member 832 is filled between the atomizer tube 82 and the mounting tube 831, and covers the first liquid guide hole 821 and the liquid guide hole, the heating member 834 is arranged in the mounting tube 831, the second liquid guide member 833 is filled between the heating member 834 and the mounting tube 831, and covers the second liquid guide hole 8311.

[0081] The aerosol matrix in the liquid storage chamber 70 will enter the first liquid guiding member 832 through the first liquid guiding hole 821, enter the second liquid guiding hole 8311 after passing through the first liquid guiding member 832, and then contact the heating member 834 after passing through the second liquid guiding member 833, and be heated by the heating member 834 in the powered state to form an aerosol.

[0082] By providing the first liquid guide member 832 and the second liquid guide member 833, the locking effect of the aerosol matrix in the liquid storage chamber 70 can be effectively improved, and the risk of the aerosol matrix in the liquid storage chamber 70 leaking into the atomization channel 81 during non-use can be reduced.

[0083] Furthermore, the first shell 11 is also constructed to form a liquid collecting chamber 15, which connects the air guiding space 14 and the accommodating chamber 13 and is located on the side of the liquid locking component 60 away from the atomization assembly 80. The connecting pipe portion 12 extends out of the liquid collecting chamber 15 and is connected to the airflow diverting component 20.

[0084] By setting up the liquid collecting chamber 15, the aerosol matrix or condensate dripping from the liquid locking part 60 or from the air guiding space 14 can be collected in the liquid collecting chamber 15, thereby further improving the interception effect of the aerosol matrix and the condensate, and further reducing the risk of leakage of the aerosol matrix or the condensate from the air inlet 121.

[0085] Preferably, a liquid-locking cotton may be provided in the liquid collecting chamber 15 to lock the aerosol matrix or condensed liquid collected in the liquid collecting chamber 15 .

By providing the annular protrusions 221, it is possible to support and limit the side of the liquid locking member 60 close to the liquid collecting cavity 15, and it is also possible to guide the aerosol matrix or condensed liquid that cannot be effectively locked after the liquid locking member 60 is saturated, so that the guided aerosol matrix or condensed liquid can flow directly to the liquid collecting cavity 15.

[0087] Furthermore, an annular protrusion 223 is formed on the inner wall of the second section 22, and the annular protrusion 223 has a first blocking surface 2231 and a first air guiding surface 2232, wherein the first blocking surface 2231 faces the air outlet end 227 and is used to prevent the condensate from passing over the annular protrusion 223, thereby further intercepting the aerosol matrix or the condensate; the first air guiding surface 2232 faces away from the air outlet end 227, and is used to guide the airflow to pass over the annular protrusion 223, so that the airflow can smoothly pass over the annular protrusion 223 and enter the air guiding space 14.

[0088] Furthermore, the inner wall of the second section 22 is formed with a plurality of annular protrusions 223, and adjacent annular protrusions 223 are arranged at intervals, so that a second liquid collecting groove 224 is formed between adjacent annular protrusions 223 and the corresponding inner wall of the second section 22. The second liquid collecting groove 224 is used to collect the aerosol matrix or condensate intercepted by the first blocking surface 2231.

[0089] Furthermore, along the direction of the airflow passing through the second section 22 and entering the accommodating chamber 13, the apertures between the plurality of annular protrusions 223 gradually increase, so that the annular protrusion 223 close to the air outlet end 227 has a first blocking surface 2231 with a larger area relative to the annular protrusion 223 far from the air outlet end 227, thereby achieving more effective interception of the aerosol matrix or condensate on the side close to the air outlet end 227.

Therefore, the electronic atomization device also has all the beneficial effects of the above-mentioned atomizer 100, which will not be repeated here.

[0091] Furthermore, the electronic atomization device also includes a power supply component and a control component, and the control component is electrically connected to the power supply component and the heating element 834 in the atomization component 80, respectively, so as to control the power supply component to supply power to the control component and the heating element 834, and control the heating element 834 to heat the aerosol matrix, so that the heated aerosol matrix generates aerosol.

[0092] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0093] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. Unless otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of this application.
