[0023] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0024] Combination Figure 1 and Figure 2 The embodiment of the present application provides an atomizing device 1. The atomizing device 1 includes a housing 11, a nozzle 12, a fixed bracket 13 and a rotating bracket 14.

[0025] The housing 11 can provide a space for installing components such as the fixed bracket 13, the rotating bracket 14 and the suction nozzle 12, and can provide mechanical support for them. The housing 11 can also be held by the user for easy use. For ease of description, the housing 11 described in this application has a first end and a second end. The first end and the second end refer to the two ends of the housing 11, respectively. Figure 2 The end with the suction nozzle 12 may be the first end, and the other opposite end may be the second end.

[0026] The fixing bracket 13 is disposed in the housing 11. The fixing bracket 13 can divide the space inside the housing 11 in the housing 11, thereby forming a space for installing different components, such as the rotating bracket 14 and the atomizer 20. The fixing bracket 13 can provide mechanical support for different components and space different components to reduce mutual influence between different components during operation.

[0027] Furthermore, combined with Figure 2 and Figure 3The fixed bracket 13 includes a fixed base 131 and a fixed shaft 132. The fixed base 131 can separate the space inside the housing 11 into a portion close to the first end of the housing 11 and a portion close to the second end of the housing 11. In this way, components of the atomizer 20 that realize different functions can be installed at intervals on both sides of the fixed base 131, and the structural layout of the atomization device 1 can be optimized. The fixed shaft 132 extends from the fixed base 131 toward the first end of the housing 11. The fixed shaft 132 can provide support for the rotating bracket 14, and the rotating bracket 14 can rotate around the fixed shaft 132.

[0028] The rotating bracket 14 is rotatably disposed in the housing 11. The rotating bracket 14 is sleeved on the fixed rotating shaft 132, and the fixed rotating shaft 132 can support the rotating bracket 14 and enable the rotating bracket 14 to rotate around the fixed rotating shaft 132. The rotating bracket 14 is used to carry at least two atomizers 20. The rotating bracket 14 can drive at least two atomizers 20 to rotate relative to the housing 11. The atomizer 20 has a working position. When the atomizer 20 is in the working position, the atomization core in the atomizer 20 is connected to the battery 30, and the atomization channel in the atomizer 20 is connected to the air inlet channel 1341. The rotating bracket 14 can drive at least two atomizers 20 to rotate, so that different atomizers 20 can be in the working position.

[0029] The atomizer 20 includes an atomizing housing, in which a liquid storage space and an atomizing channel are formed. The liquid storage space is used to store the atomizing matrix. An atomizing core is arranged in the atomizing channel. The liquid storage space is connected to the atomizing channel, and the atomizing matrix in the liquid storage space can flow to the atomizing core, and the atomizing core can atomize the atomizing matrix into an aerosol. The aerosol is dispersed in the atomizing channel, and the user can inhale the aerosol by sucking the atomizing device 1.

[0030] In some embodiments, in combination Figure 4 The rotating bracket 14 includes a housing 141 and a sleeve 142. The sleeve 142 is sleeved on the fixed rotating shaft 132, and the housing 141 is sleeved with the sleeve 142. A spacer 143 is connected between the housing 141 and the sleeve 142, and the spacer 143 is spaced in the circumferential direction of the sleeve 142. The spacer 143 can separate a space for installing the atomizer 20. The atomizer 20 is arranged in the space defined by two adjacent spacers 143. The spacer 143 can push the atomizer 20 to rotate together during the rotation of the rotating bracket 14.

[0031] In some embodiments, in combination Figure 1 and Figure 2 The housing 11 is provided with a sliding window 111 on its circumference, and the housing 141 is exposed to the outside through the sliding window 111. In this way, the user can contact the rotating bracket 14 through the sliding window 111, and further can rotate the rotating bracket 14 through the sliding window 111.

[0032] In some embodiments, a suction nozzle 12 is provided at the first end of the shell 11, and the toggle window 111 and the suction nozzle 12 are arranged on the same side relative to the fixed rotating shaft 132. Specifically, the suction nozzle 12 includes a covering portion and a suction portion, and the covering portion covers the first end of the shell 11, and can enclose the rotating bracket 14 and the atomizer 20 in the shell 11. The suction portion is connected to the covering portion and is located on the side of the covering portion away from the shell 11. An air outlet channel is provided through the suction portion and the covering portion for supplying aerosol air. Among them, the suction portion is eccentrically arranged relative to the fixed rotating shaft 132, and is corresponding to at least one atomizer 20 in a working position in the shell 11. Furthermore, the toggle window 111 and the suction portion are located on the same side relative to the fixed rotating shaft 132, so that the structure of the atomizing device 1 is more in line with the user's usage habits and improves the user experience.

[0033] In some embodiments, in combination Figure 2 The atomizing device 1 further includes a stopper 15. The stopper 15 is fixedly mounted on one side of the fixed rotating shaft 132 close to the first end, and is used to abut against the rotating bracket 14 to limit the movement of the rotating bracket 14 in the axial direction of the fixed rotating shaft 132, thereby preventing the atomizing device 1 from excessively shaking from the housing 11 or even falling out of the housing 11 during use.

[0034] In some embodiments, the rotating bracket 14 includes a sleeve 142 sleeved on the fixed rotating shaft 132, the sleeve 142 extends along the axis direction of the fixed rotating shaft 132, and the end of the sleeve 142 close to the first end abuts against the limiter 15 to limit the movement of the rotating bracket 14 toward the first end. On the one hand, the sleeve 142 can form a rotation pair with the fixed rotating shaft 132, and on the other hand, the end surface of the sleeve 142 can abut against the limiter 15, thereby limiting the movement of the rotating bracket 14 on the rotation axis.

[0035] Optionally, in other embodiments, the rotating bracket 14 includes a limiting portion extending from the end of the shaft sleeve 142 in a direction perpendicular to the rotation axis, and the limiting portion can abut against the limiting member 15 to limit the movement of the rotating bracket 14. The limiting portion can limit the rotating bracket 14 by extending into the gap between the limiting member 15 and the fixed rotating shaft 132, thereby improving the stability of the limit.

[0036] In some embodiments, the outer diameter of at least a portion of the stopper 15 near the first end is larger than the outer diameter of at least a portion of the stopper 15 near the second end. In this way, the stopper 15 can be formed with a step surface. The end surface of the sleeve 142 can easily abut the step surface to limit the movement of the rotating bracket 14 in the axial direction of the fixed shaft 132. The stopper 15 arranged in the above manner can achieve the above-mentioned limitation during the assembly process by installing the rotating bracket 14 to the fixed shaft 132 and then installing the stopper 15 to the fixed shaft 132. It is simple and convenient, and the assembly efficiency is high.

[0037] In some embodiments, the limit member 15 is provided with a fixing hole, the fixed shaft 132 is provided with an installation hole, the fixing member 151 is penetrated by the fixing hole and the installation hole, the inner diameter of the fixing hole close to the fixed shaft 132 is smaller than the inner diameter of the part away from the fixed shaft 132, and a flange is provided at one end of the fixing member 151 close to the limit member 15, and the flange abuts the limit member 15 to install the limit member 15 on the fixed shaft 132.

[0038] In some embodiments, the atomizer 1 further comprises a nozzle 12, which is mounted at the first end of the housing 11. When the atomizer 20 is in the working position, the air outlet passage of the nozzle 12 can be communicated with the atomization passage of the atomizer 20 in the working position, so that the aerosol can be discharged through the air outlet passage. Optionally, one of the engaging portion or the engaging groove is provided on the side of the stopper 15 close to the nozzle 12, and the other of the engaging portion or the engaging groove is provided on the side of the nozzle 12 close to the stopper 15. The engagement of the engaging portion and the engaging groove can limit the rotation of the nozzle 12 relative to the housing 11.

[0039] In some embodiments, in combination Figure 3 and Figure 5 , the fixed bracket 13 also includes a support member 133. The support member 133 extends from the fixed base 131 toward the second end of the shell 11. The support member 133 and the shell 11 form an installation space, and the installation space is used to install the battery 30. On the one hand, the standard-produced battery 30 has standardized specifications, and the structure of the atomizer 1 needs to be adapted to the battery 30 to avoid the use of non-standard batteries 30, which can reduce costs. On the other hand, in addition to the battery 30, the atomizer 1 also needs to accommodate components such as the control board 17 and the airflow sensing device 18, and the structure of the atomizer 1 also needs to take into account the installation of components other than the battery 30. By providing the support member 133, on the one hand, a suitable installation space that is adapted to the specifications of the battery 30 can be formed, and on the other hand, a space for installing components such as the control board 17 and the airflow sensing device 18 and separated from the battery 30 can be formed.

[0040] Specifically, in some embodiments, the support member 133 has a first abutting portion 1331 and a second abutting portion 1332, the surface of the first abutting portion 1331 facing the battery 30 is arranged in an arc shape, the surface of the second abutting portion 1332 facing away from the battery 30 is arranged in a plane, and the first abutting portion 1331 and the inner wall of the housing 11 are surrounded to form an installation space. For a circular battery 30, the arc-shaped surface of the first abutting portion 1331 can better fit the battery 30, so that the contact area with the battery 30 can be increased as much as possible when the volume of the first abutting portion 1331 is limited, so as to improve the stability of the installation of the battery 30. Optionally, the arc of the surface of the first abutting portion 1331 facing the battery 30 is on the circumference of a concentric circle with the surface of the battery 30.

[0041] In some embodiments, two or more support members 133 may be provided. The support members 133 may also be symmetrically arranged, with the axis of symmetry passing through the center of the battery 30. Further, the axis of symmetry may be a line connecting the geometric center of the housing 11 and the geometric center of the battery 30 in the same cross section. In this way, the stability of the installation of the battery 30 can be further increased.

[0042] In other embodiments, the battery 30 may not be circular, in which case the shape of the first abutting portion 1331 may be configured to conform to the shape of the battery 30 to ensure the stability of the installation of the battery 30 .

[0043] In some embodiments, in combination Figure 5 The airflow sensing device 18 is disposed on the side of the second abutting portion 1332 away from the first abutting portion 1331, and the airflow sensing device 18 is connected to the atomizer 20. The airflow sensing device 18 can sense the user's inhalation, thereby sending a signal to put the atomizer 20 in a working state. The airflow sensing device 18 is disposed on the side of the second abutting portion 1332 away from the first abutting portion 1331, which can separate the airflow sensing device 18 from the battery 30 to reduce the influence between them. In addition, the second abutting portion 1332 can cooperate with the side wall of the housing 11 to improve the stability of the installation of the airflow sensing device 18.

[0044] In some embodiments, an airflow sensing device 18 is further provided on the side of the support member 133 away from the installation space. A control board 17 is further provided between the support member 133 and the airflow sensing device 18. The support member 133 and the airflow sensing device 18 can sandwich the control board 17, which can facilitate the connection between the airflow sensing device 18 and the control board 17 on the one hand, and can increase the stability of the installation of the control board 17 with the cooperation of the support member 133 on the other hand. Optionally, the control board 17 is provided between the second abutting portion 1332 and the airflow sensing device 18, and the plane of the second abutting portion 1332 can better sandwich the control board 17.

[0045] In some embodiments, in combination Figure 5 and Figure 7 A clamping member 135 is provided from the fixed base 131 toward the second end of the housing 11, and the control board 17 is provided between the clamping member 135 and the support member 133. The clamping member 135 cooperates with the support member 133 to further increase the stability of the installation of the control board 17. Optionally, the extension length of the clamping member 135 is less than the extension length of the support member 133. The support member 133 needs to have a sufficient length to stably support the battery 30, but if the length of the clamping member 135 is too long, it will affect the arrangement of the components on the surface of the control board 17, which is not conducive to improving the space utilization.

[0046] In some embodiments, the thickness direction of the control board 17 is perpendicular to the axis direction of the fixed rotation shaft 132. The length or width direction of the control board 17 is along the axis direction of the fixed rotation shaft 132.

[0047] In some embodiments, in combination Figure 2 and Figure 3 , the fixed base 131 is provided with a sealing groove 134 opening toward the first end, and the sealing groove 134 can accommodate a sealing member 16. A sealing member 16 is installed in the sealing groove 134. The sealing member 16 is arranged corresponding to at least one atomizer 20. An air inlet channel 1341 runs through the sealing member 16 and the bottom wall of the sealing groove 134, and the air inlet channel 1341 is connected to the atomizer 20. The air inlet channel 1341 can connect the side of the fixed base 131 close to the second end with the side of the fixed base 131 close to the first end, and with the assistance of the sealing member 16, the air inlet channel 1341 can be connected to the atomization channel of the atomizer 20. The sealing member 16 can abut against the bottom of the atomizer 20, so that the connection between the atomization channel and the air inlet channel 1341 is sealed during the process of the atomization channel and the air inlet channel 1341 being connected. The sealing member 16 can also be used to form the air inlet channel 1341 and to penetrate the electrode terminal, etc. The air inlet channel 1341 includes two parts, one of which is opened in the seal 16, and the other part is penetrated through the bottom wall of the seal groove 134. In some embodiments, the seal 16 is formed with a receiving groove, which can form a receiving space with the bottom of the atomizer 20, and the air inlet channel 1341 can be indirectly connected with the atomizer 20 through the receiving space, so that the atomizer 20 and the air inlet channel 1341 do not need to be precisely docked to achieve airflow transmission. The receiving groove can also accommodate condensed liquid or atomized matrix that may leak from the atomizer 20 to reduce the leakage of the atomizing device 1.

[0048] In some embodiments, an airflow sensing device 18 is further provided on one side of the fixed base 131 near the second end, and an airflow sensing channel 1342 penetrates the seal 16 and the bottom wall of the sealing groove 134, and the airflow sensing channel 1342 connects the atomizer 20 and the airflow sensing device 18. The airflow sensing channel 1342 includes two parts, one part of which penetrates the bottom wall of the sealing groove 134, and the other part penetrates the seal 16. The airflow sensing channel 1342 can transmit the negative pressure of the user's inhalation to the airflow sensing device 18. The airflow sensing device 18 can detect the user's inhalation, thereby controlling the operation of the atomizer core through the control board 17.

[0049] In some embodiments, the rotating bracket 14 is used to drive at least two atomizers 20 to rotate relative to the housing 11 . The at least two atomizers 20 can be arranged corresponding to the airflow sensing device 18 through rotation, and the airflow sensing device 18 is connected to the corresponding atomizer 20 .

[0050] In some embodiments, in combination Figure 6 and Figure 7 A mounting seat 136 is provided on the side of the fixed base 131 away from the rotating bracket 14. The mounting seat 136 has a mounting groove 1360. The mounting groove 1360 is used to mount the airflow sensing device 18. The bottom wall of the mounting groove 1360 and the bottom wall of the sealing groove 134 are at least partially the same bottom wall. The airflow sensing channel 1342 can penetrate the bottom wall to connect the mounting groove 1360 and the sealing groove 134. The mounting seat 136 can be used to fix the airflow sensing device 18 and provide support and positioning for the airflow sensing device 18.

[0051] Specifically, in some embodiments, the mounting seat 136 includes a first side wall 1361 and a second side wall 1362, the first side wall 1361 and the second side wall 1362 extending in a perpendicular direction, and the plurality of first side walls 1361, the second side walls 1362 and the fixed base 131 are surrounded to form a mounting groove 1360, and the mounting groove 1360 has an opening toward the side wall of the housing 11. The first side wall 1361 extends from the fixed base 131 in a direction close to the second end, and the second side wall 1362 is perpendicular to the direction perpendicular to the extending direction of the second side wall 1362 from the end wall of the first side wall 1361. At least two first side walls 1361 and the second side wall 1362 may be symmetrically arranged as a whole, and the second side walls 1362 extend toward each other, thereby surrounding a T-shaped mounting groove 1360. At least a portion of the airflow sensing device 18 can be installed into the mounting seat 136 from the opening of the mounting groove 1360.

[0052] In some embodiments, when the atomizer 1 is in use, the gravity direction of the airflow sensing device 18 is nearly perpendicular to the opening direction of the mounting slot 1360, and the mounting seat 136 can achieve stable installation of the airflow sensing device 18. Furthermore, the airflow sensing device 18 can be assembled with the mounting seat 136 first, and then the whole assembly can be assembled with the housing 11.

[0053] Furthermore, the mounting seat 136 can be arranged at the edge of the fixed base 131. In this way, the side wall of the housing 11 can block or close the opening of the mounting groove 1360 to a certain extent after the atomizer 1 is assembled and assembled, so as to play a limiting role and further improve the stability of the installation of the airflow sensing device 18. At the same time, the mounting seat 136 is arranged at the edge, which can also facilitate the matching of the airflow sensing device 18 and the atomizer 20.

[0054] In some embodiments, in combination Figure 2 and Figure 6 The airflow sensing device 18 includes a device body 181 and a device cover 182. The device includes a wrapping portion 1821 that wraps the device body 181 and an insertion portion 1822 for cooperating with the mounting groove 1360. The insertion portion 1822 includes a first extension portion 1822A and a second extension portion 1822B. The first extension portion 1822A extends from the wrapping portion 1821 along a first direction, and the second extension portion 1822B extends from the first extension portion 1822A along a second direction. The first direction is a direction away from the device body 181, and the second direction is perpendicular to the first direction. In other words, the device cover 182 has a "T-shaped" insertion portion 1822. In the above manner, the airflow sensing device 18 can be adapted to the mounting seat 136 to achieve stable installation of the airflow sensing device 18.

[0055] In other embodiments, the mounting seat 136 includes a plurality of side walls disposed from the fixed base 131 toward the second end, the plurality of side walls are surrounded to form a mounting groove 1360, and the opening of the mounting groove 1360 is disposed toward the second end. In this way, the airflow sensing device 18 can be installed in the mounting groove 1360 from the second end toward the first end. The airflow sensing device 18 can be connected to the mounting seat 136 by interference fit or snap fit.

[0056] The above are merely embodiments of the present application and are not intended to limit the patent scope of the present application.
