Thus, other examples of exemplary embodiments can have different values. It is noted that like numbers and letters refer to like elements throughout the several views of the drawings and, as such, no further discussion with regard thereto is deemed necessary.

[0037] Referring to Figures 1-5 As shown in the drawings, in one aspect, the present application provides an atomizer 100, which comprises a housing 10, a mounting seat 20 and an atomization assembly 30, wherein the mounting seat 20 and the atomization assembly 30 are respectively arranged in the housing 10.

[0038] The housing 10 is configured to form a receiving space; the mounting seat 20 divides the receiving space into a first space and a second space 101 in the housing 10; the atomization assembly 30 is arranged in the first space, and a liquid storage chamber 102 is defined between the atomization assembly 30, the mounting seat 20 and the housing 10; the atomization assembly 30 is used to heat an aerosol substrate contained in the liquid storage chamber 102, so that the heated aerosol substrate is atomized to generate an aerosol.

[0039] Further, referring to Figures 2-3As shown, the atomization assembly 30 has an air inlet end 31, an air outlet end 32, and an atomization channel 33 communicated between the air inlet end 31 and the air outlet end 32. The mounting base 20 is configured with a liquid collecting groove 211, an air passing channel 221, and a recovery channel 231. The liquid collecting groove 211 faces the first space, the air outlet end 32 is sealingly inserted into the shell 10, and the air inlet end 31 is sealingly inserted into the liquid collecting groove 211, so that the condensed liquid in the atomization channel 33 can flow / drop into the liquid collecting groove 211 under the action of gravity to achieve interception of the condensed liquid. The air passing channel 221 communicates the atomization channel 33 and the second space 101, so that the condensed liquid that drips through the air passing channel 221 can be intercepted again through the second space 101, thereby achieving double interception of the condensed liquid and reducing the risk of condensed liquid leakage. Further, the air passing channel 221 extends from the bottom of the liquid collecting groove 211 to the first space, so that the liquid collecting groove 211 is arranged around the side of the air passing channel 221, thereby facilitating smooth passage of external airflow through the liquid collecting groove 211 to enter the atomization channel 33, thereby reducing the suction resistance of suction and improving the user experience.

[0040] Further, the recovery channel 231 communicates the liquid collecting groove 211 and the second space 101, and the recovery channel 231 extends to the second space 101; so that in the state of user suction, the negative pressure generated in the recovery airway will drive the condensed liquid in the second space 101 to enter the liquid collecting groove 211 through the recovery channel 231, and the condensed liquid in the liquid collecting groove 211 will flow along the inner wall of the atomization channel 33 towards the direction away from the liquid collecting groove 211 along with the airflow in the atomization airway, until it is heated and atomized again by the atomization assembly 30 to form an aerosol, thereby achieving recycling of the condensed liquid, and thereby reducing the amount of condensed liquid accumulated in the liquid collecting groove 211 and the second space 101, thereby reducing the risk of condensed liquid leakage.

[0041] Further, as shown in Figure 2 、 4 -5, the mounting base 20 includes a base body 21, a first pipe portion 22, and a second pipe portion 23. The base body 21 is arranged in the shell 10 and is configured to form the liquid collecting groove 211 and to separate the accommodation space into the first space and the second space 101. The first pipe portion 22 penetrates the base body 21 and extends into the liquid collecting groove 211 to define the air passing channel 221. The second pipe portion 23 penetrates the base body 21 and extends into the second space 101 to define the recovery channel 231.

[0042] The aperture of the recovery channel 231 is smaller than that of the air passing channel 221, and the surface tension of the aerosol substrate in the liquid collecting groove 211 at the recovery channel 231 is greater than the gravity, so that the condensed liquid in the liquid collecting groove 211 does not directly flow along the recovery channel 231 to the second space 101 due to gravity, thereby avoiding increasing the amount of condensed liquid in the second space 101, and facilitating the movement of the condensed liquid in the second space 101 to the liquid collecting groove 211 through the recovery channel 231 based on negative pressure.

[0043] Further, at least one recovery channel 231 is provided between the liquid collecting groove 211 and the second space 101, preferably two recovery channels 231 are provided between the liquid collecting groove 211 and the second space 101 to increase the efficiency of the movement of the condensed liquid in the second space 101 to the liquid collecting groove 211.

[0044] Further, at least one atomization assembly 30 is provided in the first space. Preferably, two atomization assemblies 30 are provided in the first space, and the mounting seat 20 is provided with one liquid collecting groove 211 corresponding to each atomization assembly 30, and one air passing channel 221 and at least one recovery channel 231 corresponding to each liquid collecting groove 211. By providing two atomization assemblies 30, the amount of aerosol generated can be effectively increased.

[0045] Further, referring to Figures 1-2 As shown, the atomizer 100 further includes a liquid storage member 40 provided in the second space 101, so that the condensed liquid in the second space 101 can be latched by the liquid storage member 40, avoiding the risk of leakage of the condensed liquid in the second space 101 when the atomizer 100 is placed obliquely or upside down.

[0046] Further, the recovery channel 231 extends to the end of the second space 101 close to or in contact with the liquid storage member 40, so that the condensed liquid latched by the liquid storage member 40 can move to the liquid collecting groove 211 through the recovery channel 231 under the action of negative pressure.

[0047] Further, the atomization channel 33 is coaxially arranged with the air passing channel 221, so that the air passing channel 221 is vertically located directly below the atomization channel 33, so as to facilitate the smoother entry of external airflow into the atomization channel 33 through the air passing channel 221, thereby reducing the suction resistance when the user inhales.

[0048] Please refer to Figure 2 , 5As shown, the aperture of the air passage 221 near the atomizing channel 33 is smaller than the minimum aperture of the atomizing channel 33. This allows the condensate in the atomizing channel 33 to drip directly into the collection tank 211 when the atomizer 100 is placed vertically and the air passage 221 is located below the atomizing channel 33. This facilitates the condensate flowing directly from the collection tank 211 with the airflow in the atomizing channel to the atomizing component 30, where it is reheated and atomized by the atomizing component 30 to generate an aerosol. This also reduces the risk of the condensate dripping directly into the second space 101.

[0049] The aperture of the air passage 221 can be consistent along the direction of airflow or it can gradually decrease along the direction of airflow.

[0050] Further, please refer to Figures 2-3 As shown, the atomizing assembly 30 includes an atomizing tube 34, a first liquid guiding element 35, and a heating element 36. The first liquid guiding element 35 is disposed within the atomizing tube 34, and the heating element 36 is disposed inside the first liquid guiding element 35. The first liquid guiding element 35 encloses and forms a portion of the minimum aperture of the atomizing channel 33, that is, the first liquid guiding element 35 defines the minimum aperture forming the atomizing air passage.

[0051] Since the first liquid guiding element 35 is generally made of cotton material, it also has a locking function for the aerosol matrix. Therefore, when the atomizer 100 is placed vertically and the air passage 221 is located below the atomization channel 33, the condensate formed in the atomization channel 33 above the first liquid guiding element 35 will be absorbed and locked by the first liquid guiding element 35, and will be heated again to generate aerosol when the heating element 36 is heating. The condensate formed in the atomization channel 33 below the first liquid guiding element 35 will flow along the inner wall of the atomization channel 33 into the liquid collection tank 211, thereby reducing the risk that the condensate in the atomization channel 33 will directly drip into the second space 101 through the air passage 221.

[0052] Furthermore, the atomizing assembly 30 also includes a fixing tube 37 and a second liquid guiding member 38. The second liquid guiding member 38 is disposed inside the atomizing tube 34 and surrounds the outside of the first liquid guiding member 35. The fixing tube 37 is inserted into the atomizing tube 34 and abuts against the bottom of the liquid collecting tank 211, so as to seal the connection between the outer wall of the atomizing tube 34 and the tank wall of the liquid collecting tank 211, thereby preventing the aerosol matrix contained in the liquid storage chamber 102 from leaking between the outer wall of the atomizing tube 34 and the tank wall of the liquid collecting tank 211.

[0053] Further, the first liquid guide 35 is arranged on the inner wall of the fixed tube 37, and the second liquid guide 38 is arranged on the outer wall of the fixed tube 37, so that the first liquid guide 35 and the second liquid guide 38 are arranged in the atomization tube 34 through the fixed tube 37 respectively.

[0054] The atomization tube 34 is provided with a first liquid guide hole 341, and the fixed tube 37 is provided with a second liquid guide hole 371. The second liquid guide 38 covers the first liquid guide hole 341 and the second liquid guide hole 371 on the inner wall of the atomization tube 34 and the outer wall of the fixed tube 37. The first liquid guide 35 covers the second liquid guide hole 371 on the inner wall of the fixed tube 37.

[0055] The second liquid guide 38 is generally made of cotton material, so the second liquid guide 38 also has a latching function for the aerosol substrate. Therefore, by arranging the first liquid guide 35 and the second liquid guide 38, the atomization assembly 30 has stronger latching ability for the aerosol substrate contained in the liquid storage compartment 102, thereby reducing the risk of leakage of the aerosol substrate in the liquid storage compartment 102 through the first liquid guide hole 341 and the second liquid guide hole 371 in a non-use state.

[0056] Further, referring to Figure 2 As shown in the figure, the fixed tube 37 gradually reduces the aperture along the direction from the air inlet end 31 to the air outlet end 32, so that the inner wall of the fixed tube 37 is an annular inclined surface inclined towards the first liquid guide 35. Therefore, in the state of user suction, the condensate in the liquid collecting groove 211 will move more smoothly along the annular inclined surface to the first liquid guide 35, so as to improve the efficiency of recycling the condensate in the liquid collecting groove 211.

[0057] Further, the shell 10 includes a first shell 11, a second shell 12 and a third shell 13. The second shell 12 is sealingly connected between the first shell 11 and the third shell 13, and the first shell 11 is configured to form a suction nozzle 111. The suction nozzle 111 communicates with one end of the atomization channel 33 away from the air passing channel 221. When suctioning, the aerosol generated in the atomization channel 33 will be mixed into the passing airflow and flow out from the suction nozzle 111.

[0058] Further, referring to Figures 1-2As shown, the second shell 12 and the third shell 13 are configured to form the accommodation space, and the mounting base 20 is sealingly connected between the second shell 12 and the third shell 13, so that the second shell 12 and the third shell 13 are sealingly connected to avoid leakage of the condensed liquid in the second space 101 from the connection between the second shell 12 and the third shell 13; and the accommodation space is divided to form the first space and the second space 101.

[0059] Further, the second shell 12 is configured to form an air inlet passage 121, which communicates with the second space 101. External airflow enters the shell 10 through the air inlet passage 121, and continues to flow through the second space 101, the air passage 221, the atomization passage 33, and the suction nozzle 111, and then flows out of the atomizer 100. The airflow mixes with the generated aerosol at the heating element 36, and then flows out of the atomizer 100 together from the suction nozzle 111.

[0060] Further, referring to Figures 1-2 As shown, the atomizer 100 further includes an air adjusting member 50, which is arranged on the shell 10 and is used to adjust the airflow through the air inlet passage 121.

[0061] The air adjusting member 50 is slidingly and sealingly arranged in the air inlet passage 121. In some embodiments, the air adjusting member 50 is provided with a first air passage hole 51 and a second air passage hole 52 having different diameters, and the air adjusting member 50 has a first position, a second position, and a third position. When the air adjusting member 50 is in the first position, the air adjusting member 50 blocks the air inlet passage 121, so that external airflow cannot enter the atomizer 100. When the air adjusting member 50 is in the second position, external airflow can enter the air inlet passage 121 through the first air passage hole 51. When the air adjusting member 50 is in the third position, external airflow can enter the air inlet passage 121 through the second air passage hole 52.

[0062] Further, referring to Figure 2 As shown, the atomizer 100 further includes an air tube 60, which is connected between the second shell 12 and the third shell 13 and forms a detection air passage 103 with the shell 10. The detection air passage 103 is used for detection airflow to flow, so that an airflow sensor in communication with the detection air passage 103 can detect the user's puffing, so as to generate a detection signal according to the user's puffing, and feed the detection signal to the control assembly, so that the control assembly controls the heating element 36 to work according to the detection signal.

[0063] The detection air passage 103 is independent of the air inlet passage 121, the air passing passage 221 and the atomization passage 33, so that the condensed liquid generated in the atomization passage 33 can be effectively prevented from flowing to the air flow sensor through the detection air passage 103 and causing the air flow sensor to be short-circuited.

[0064] Further, referring to Figures 1-2 As shown, the second shell 12 is further provided with a filling hole, which is communicated with the liquid storage compartment 102. The atomizer 100 further comprises a sealing plug 70, which is sealingly and openably arranged on the filling hole. When the aerosol substrate in the liquid storage compartment 102 is consumed, the aerosol substrate can be filled into the liquid storage compartment 102 through the filling hole, so that the atomizer 100 can be continuously used.

[0065] In another aspect, the present application further provides an electronic atomization device, which comprises the above-mentioned atomizer 100. Therefore, the electronic atomization device also has all the beneficial effects of the above-mentioned atomizer 100, which will not be described here again.

[0066] Further, the electronic atomization device further comprises a power supply assembly and a control assembly. The control assembly is electrically connected with the power supply assembly and the heating element 36 in the atomization assembly 30, respectively, so as to control the power supply assembly to supply power to the control assembly and the heating element 36, and to control the heating element 36 to heat the aerosol substrate, so that the heated aerosol substrate generates aerosol.
