[0081] The electronic atomization device is provided by the embodiments of the present application.

[0082] Please refer to Figures 1 to 8In the first embodiment, the electronic atomization device comprises a housing 100, an atomizer assembly 200, an airway control part 300, and a mouthpiece assembly 400. The housing 100 has a mounting cavity with one side open and an airway switching area 110, and the airway switching area 110 is provided with a first air hole 111 and a second air hole 112. The atomizer assembly 200 comprises a first atomizer 210 and a second atomizer 220 which are independently arranged in the mounting cavity, the first atomizer 210 has a first atomization airway 211, and the second atomizer 220 has a second atomization airway 221. The mouthpiece assembly 400 comprises a mouthpiece 700 which is arranged on the housing 100, and the housing 100 has an air inlet channel formed inside for communication with the outside, which specifically comprises a first air inlet channel 711 and a second air inlet channel 721. It should be understood by those skilled in the art that the first air inlet channel 711 is provided with a first pneumatic switch 712, and the second air inlet channel 721 is provided with a second pneumatic switch 722, and the two pneumatic switches are respectively electrically connected with a control mainboard, the control mainboard is electrically connected with a battery, and the control mainboard is also electrically connected with the first atomizer 210 and the second atomizer 220. The airway control part 300 is arranged on the airway switching area 110, and the airway control part 300 has a first state, a second state and a third state which can be switched under the action of external force. In this application, the first air hole 111 and the second air hole 112 can be corresponding air inlets, corresponding atomizer inlets, and aerosol outlets, etc. For example, in the first embodiment shown in Figure 1 and Figure 8 , the first air hole 111 is an air inlet arranged at one end of the housing 100 away from the mouthpiece 700, and the second air hole 112 is another air inlet arranged at the other end of the housing 100 away from the mouthpiece 700.

[0083] As shown in Figures 1 to 3 , Figure 5 , Figure 6 and Figure 8 , in the first state, the airway control part 300 opens the first air hole 111, so that the mouthpiece 700, the first atomization airway 211 of the first atomizer 210, and the first air inlet channel 711 are in communication with the outside, forming a fluid communication, so that when the user inhales, the outside air can enter the first air inlet channel 711 from the first air hole 111, and flow through the first pneumatic switch 712, the air flow triggers the start switch, and the first pneumatic switch 712 feeds back a trigger signal to the control mainboard after detecting the air flow, so that the control mainboard controls the battery to supply power to the first atomizer 210, so that the first atomizer 210 starts to work, and the first atomizer 210 generates aerosol; after the air flow flows through the first pneumatic switch 712, it enters the first atomization airway 211 to drive the aerosol generated by the first atomizer 210 to be delivered to the mouthpiece 700 for the user to inhale.

[0084] Similarly, in the second state, the airway control part 300 opens the second air hole 112, so that the suction nozzle 700, the second atomization airway 221 of the second atomizer 220, and the second air inlet channel 721 are communicated with the outside, forming fluid communication, when the user inhales, the outside air can enter the second air inlet channel 721 from the second air hole 112, and flow through the second pneumatic switch 722, the air flow triggers the start switch, the second pneumatic switch 722 feeds back a trigger signal to the control mainboard after detecting the air flow, so that the control mainboard controls the battery to supply power to the second atomizer 220, so that the second atomizer 220 can start to work, and the second atomizer 220 generates aerosol which is delivered to the user through the suction nozzle.

[0085] In the third state, the airway control part 300 simultaneously opens the first air hole 111 and the second air hole 112, and the first atomization airway 211 and the second atomization airway 221 are both in fluid communication with the suction nozzle and the corresponding air inlet channel, and the first atomizer 210 and the second atomizer 220 can both start to work, and the aerosols generated by the first atomizer 210 and the second atomizer 220 are mixed in the suction nozzle and then delivered to the user.

[0086] Based on the structure design, in the present application, since the airway control part 300 is arranged on the electronic atomization equipment with double atomizers, in the actual use process, the user can operate the airway control part according to his own needs, and the airway control part 300 can be switched to the first state, the second state and the third state under the action of external force. When the airway control part 300 is in the first state, the first air hole 111 is opened, so that the first air inlet channel 711, the first atomization airway 211 and the suction nozzle 700 are in fluid communication, so that the first atomizer works alone to generate one kind of aerosol; when the airway control part 300 is in the second state, the second air hole 112 is opened, and the second atomizer 220 works alone to generate one kind of aerosol; when the airway control part 300 is in the third state, the first air hole 111 and the second air hole 112 are both opened, and the first atomizer 210 and the second atomizer 220 work simultaneously to generate mixed aerosol. From the above use process, it can be known that in the technical solution of the present application, the user can control whether the airway of the atomization equipment is in fluid communication by selecting the state of the airway control part 300, so that the mode of one atomizer working alone or two atomizers working simultaneously can be easily realized, and the airway control part 300 has the advantages of simple structure design, convenient operation and good sealing effect.

[0087] The airway control part 300 includes a switching switch that opens and closes the first air hole 111 and the second air hole 112, and the switching switch can be a toggle switch, a rotary switch or an elastic compression switch, etc., which can switch positions under the action of external force, and in the present embodiment, the switching switch is preferably a toggle switch 310. Figures 1 to 3 and Figure 8As shown, the toggle switch 310 can move on the airway switching area 110 relative to the housing and has a first position, a second position and a third position. When the toggle switch 310 moves to the first position, the toggle switch 310 blocks the second air hole 112 and opens the first air hole 111, at this time the first air hole 111 is in communication with the outside, so that the first air inlet channel 711, the first atomization airway 211, the mouthpiece 700 are in fluid communication, so that external air can enter the first air inlet channel 711 through the first air hole 111 to trigger the first pneumatic switch 712, thereby enabling the first atomizer 210 to work when the user sucks at the mouthpiece 700. Similarly, when the toggle switch 310 moves to the second position, the toggle switch 310 blocks the first air hole 111 and opens the second air hole 112, at this time the second air hole 112 is in communication with the outside, so that the second air inlet channel 721, the second atomization airway 221, the mouthpiece 700 are in fluid communication, so that external air can enter the second air inlet channel 721 through the second air hole 112 to trigger the second pneumatic switch 722, thereby enabling the second atomizer 220 to work when the user sucks at the mouthpiece 700. When the toggle switch 310 moves to the third position, i.e. the middle position, the first air hole 111 and the second air hole 112 are both opened to communicate with the outside, and when the user sucks at the mouthpiece 700, the first atomizer 210 and the second atomizer 220 are both started to work.

[0088] To ensure that the toggle switch 310 has good sealing performance when blocking the first air hole 111 or the second air hole 112, the first sealing ring 321 is preferably arranged in the first air hole 111 and the second sealing ring 322 is arranged in the second air hole 112 in the embodiment. Specifically, as shown in Figure 2 the toggle switch 310 is toggled to the first position, the first air hole 111 is opened, and the toggle switch 310 presses the second sealing ring 322 to close the second air hole 112; as shown in Figure 3 the toggle switch 310 is toggled to the second position, the second air hole 112 is opened, and the toggle switch 310 presses the first sealing ring 321 to close the first air hole 111; as shown in Figure 1 the toggle switch 310 is toggled to the third position, the first air hole 111 and the second air hole 112 are both opened.

[0089] Please refer to Figures 1 to 5, specifically, in the embodiment, the airway switching area 110 is provided with a mounting groove 113, the toggle switch 310, the first sealing ring 321 and the second sealing ring 322 are all built-in the mounting groove 113, the first air hole 111 and the second air hole 112 are both provided at the groove bottom of the mounting groove 113 and are respectively arranged at the two sides of the toggle switch 310 along the toggle direction. Of course, in other embodiments, the mounting groove 113 can not be provided, but in the embodiment, the provision of the mounting groove 113 is beneficial to the assembly stability of the toggle switch 310, and the inner side wall of the mounting groove 113 also provides a certain limiting effect for the movement of the toggle switch 310 along the toggle direction. Here, the length extension direction of the toggle switch 310 is consistent with the length extension direction of the mounting groove 113, and the first air hole 111 and the second air hole 112 are respectively located at the two side regions of the mounting groove 113 along the length extension direction. In addition, a plurality of ribs 313 are also provided on the outer side of the toggle switch 310 away from the mounting groove 113, so as to enhance the friction between the toggle switch 310 and the fingers when the toggle switch 310 is toggled.

[0090] Further, as shown in Figure 5 , in the embodiment, the first sealing ring 321 and the second sealing ring 322 are both made of soft colloid and are arranged in a ring shape, for example, the first sealing ring 321 and the second sealing ring 322 can be made of silica gel with high heat resistance, of course, in other embodiments, the two sealing members can also be made of other materials with sealing function. The first sealing ring 321 has a first through hole 321a penetrating along the axial direction and communicating with the first air hole 111, and the second sealing ring 322 has a second through hole 322a penetrating along the axial direction and communicating with the second air hole 112, so that the air inlet of the atomizer 200 from the external environment can be realized. In addition, the ring-shaped first sealing ring 321 and the second sealing ring 322 are both provided with a limiting skirt, when the first sealing ring 321 and the second sealing ring 322 are respectively plugged into the corresponding first air hole 111 and the second air hole 112, the limiting skirt will be clamped in the corresponding air hole, so that the two sealing members are not easy to fall off from the corresponding air hole, thereby affecting the sealing effect.

[0091] Further, in the embodiment, as shown in Figure 4 and Figure 5As shown, the first sealing ring 321 is provided with a ring-shaped first sealing boss 321b protruding towards the end surface of the toggle switch 310, and the second sealing ring 322 is provided with a ring-shaped second sealing boss 322b protruding towards the end surface of the toggle switch 310; when the toggle switch 310 is toggled to the first position, the second sealing boss 322b elastically abuts against the toggle switch 310, and the second through hole 322a and the second air hole 112 are both closed; when the toggle switch 310 is toggled to the second position, the first sealing boss 321b elastically abuts against the toggle switch 310, and the first through hole 321a and the first air hole 111 are both closed. It can be understood that the provision of the first sealing boss 321b and the second sealing boss 322b can further improve the sealing performance when the toggle switch 310 elastically abuts against the corresponding sealing member, and at the same time reduce the friction force of the toggle switch 310 when being toggled.

[0092] As shown in Figure 5 , the airway control part 300 further comprises a positioning elastic pin 330 and an elastic member 340; one end of the positioning elastic pin 330 is the body of the positioning elastic pin 330, the body of the positioning elastic pin 330 is sleeved with the elastic member 340 and is installed in the accommodating groove on the airway switching area 110, and the other end of the positioning elastic pin 330 is a positioning part 331 movably connected with the inner side surface of the toggle switch 310; in this embodiment, the elastic member 340 is a spring, but it can also be, but not limited to, a pressure elastic sheet, etc. Correspondingly, the inner side surface of the toggle switch 310 is provided with a first positioning groove (not shown), a second positioning groove (not shown) and a third positioning groove (not shown) matched with the positioning part 331; when the positioning part 331 is clamped into the first positioning groove, the toggle switch 310 is in the first position; when the positioning part 331 is clamped into the second positioning groove, the toggle switch 310 is in the second position; and when the positioning part 331 is clamped into the third positioning groove, the toggle switch 310 is in the third position, so that the smooth toggling of the toggle switch 310 and the reliability of the position conversion can be realized. For example, taking the toggling of the toggle switch 310 from the first position as an example, the toggle switch 310 sequentially passes through the first position, the third position and the second position, and the positioning part 331 sequentially passes through the first positioning groove, the third positioning groove and the second positioning groove; specifically, when the positioning part 331 of the positioning elastic pin 330 is ready to slide from the first positioning groove to the third positioning groove, the spring is compressed, and then when the positioning part 331 slides to the edge of the third positioning groove, the spring elastically returns, so that the positioning part 331 can be automatically clamped into the third positioning groove, and the process of the positioning part 331 sliding from the third positioning groove into the second positioning groove is similar.

[0093] Please refer to Figure 4 and Figure 5In the embodiment, the toggle switch 310 includes a switch body 311 and a plurality of connecting buckles 312 protruding from the inner side edge of the switch body 311 towards the air passage switching area 110; the bottom of the installation slot 113 is provided with a buckle hole 114 between the first air hole 111 and the second air hole 112, the connecting buckle 312 can be buckled into the buckle hole 114, and the length of the buckle hole 114 is greater than the width of the connecting buckle 312 in the toggle direction. It can be understood that after the connecting buckle 312 is buckled into the buckle hole 114, the switch body 311 can be limited and connected in the up-down direction, and the connecting buckle can move in the transverse direction of the buckle hole with the position switching of the switch. Specifically, the design that the length of the buckle hole 114 is greater than the width of the connecting buckle 312 provides sufficient space for the movement of the toggle switch 310 in the toggle direction. Further, as shown in Figure 5 In the embodiment, a relief groove 115 is concavely arranged on the inner wall surface of the buckle hole 114 to facilitate the smooth buckling of the connecting buckle 312 into the buckle hole 114.

[0094] Please refer to Figure 6 and Figure 7 In the embodiment, the shell 100 further includes a second installation side 116 opposite to the air passage switching area 110, that is, a suction nozzle end provided with a suction nozzle 700. The suction nozzle assembly 400 includes the suction nozzle 700, a bracket 420 and a sealing sleeve 430. One side edge of the suction nozzle 700 is pivotally connected with the second installation side 116, and the other side of the suction nozzle 700 is detachably connected with the shell 100. The bracket 420 and the sealing sleeve 430 are both arranged in the suction nozzle 700. The sealing sleeve 430 can be made of silica gel, and the sealing sleeve 430 enables the suction nozzle assembly 400 to be tightly connected with the shell 100. In actual use, the suction nozzle 700 is provided with a buckle 440, and the shell 100 is provided with a button 130 at a corresponding position. The button 130 is provided with a buckle position adapted to buckle the buckle 440. When the suction nozzle 700 is forced downward, the buckle 440 on the suction nozzle 700 is adapted to buckle the buckle position of the button 130 to be locked, and the suction nozzle assembly 400 is buckled and locked with the shell 100. When the button 130 is pressed, the buckle 440 on the suction nozzle 700 is separated from the buckle position of the button 130, that is, the buckle on the suction nozzle 700 is unlocked from the buckle position of the button 130, and the suction nozzle 700 can be relatively opened, thereby facilitating the replacement of the atomizer or the removal of the atomizer for oil injection.

[0095] Further, in the embodiment, as shown in Figure 7As shown, the bracket 420 is provided with a first magnet 510 on the inner side of the second mounting side 116, the second mounting side 116 is provided with a second magnet 520 corresponding to the position of the first magnet 510, and the magnet polarities of the contact surfaces of the first magnet 510 and the second magnet 520 are the same. Thus, when the buckle 440 and the buckle position of the key 130 are unlocked, the repulsion between the first magnet 510 and the second magnet 520 automatically pops the suction nozzle 700; when the suction nozzle 700 is closed, the repulsion between the first magnet 510 and the second magnet 520 is insufficient to break the connection between the buckle 440 and the buckle position of the suction nozzle 700, that is, the suction nozzle 700 can be locked by the buckle 440 and the buckle position of the key 130.

[0096] Please refer to Figure 13 and Figure 14 In the second embodiment of the present application, the air inlet channel is connected to the outside, and the air inlet channel is connected to the first atomizing air duct 211 and the second atomizing air duct 221. Specifically, the air inlet channel can be a branch of an air duct connected to the first atomizing air duct 211 and the second atomizing air duct 221 respectively, or two air ducts connected to the first atomizing air duct 211 and the second atomizing air duct 221 respectively.

[0097] The air duct switching area is located at the top end of the shell, that is, the end provided with the suction nozzle 700. The first air hole 111 is connected to the first atomizing air duct 211 of the first atomizer 210, and the second air hole 112 is connected to the second atomizing air duct 221 of the second atomizer 220. The air duct control part 300 is installed in the air duct switching area, and the air duct control part 300 includes an air adjusting ring 371 and a fixing part 372 sleeved in the air adjusting ring 371. The air adjusting ring 371 serves as a switching switch, and the bottom of the air adjusting ring 371 has a bottom plate 371a to open or close the first air hole 111 or the second air hole 112. In this embodiment, the air adjusting ring 371 is integrally formed with the bottom plate 371a at the bottom thereof, and in other variant embodiments, the air adjusting ring 371 and the bottom plate 371a can be connected in linkage. The first end of the fixing part 372 is connected between the suction nozzle 700 and the air adjusting ring 371, and the second end of the fixing part 372 is connected with the air duct switching area on the shell 100 to install the suction nozzle 700 and the air adjusting ring 371. The second end of the fixing part 372 is provided with a first notch 372a and a second notch 372b respectively, and the outer peripheral edge of the top end of the fixing part 372 away from the shell 110 is provided with a first mark 372c and a second mark 372d respectively; the first mark 372c corresponds to the first notch 372a in position, and the second mark 372d corresponds to the second notch 372b in position; the air adjusting ring 371 is provided with a third mark 371b.

[0098] When the air adjusting ring 371 rotates to the first position, i.e., the third mark 371b of the air adjusting ring 371 corresponds to the first mark 372c, the first atomizing air passage 211 of the first atomizer 210 is communicated with the suction nozzle 700 through the first air hole 111, the first gap 372a and the second air hole 112 in sequence, and the second air hole 112 is shielded by the bottom plate 371a of the air adjusting ring 371, so that the air inlet passage, the first atomizing air passage 211, the first air hole 111 and the suction nozzle 700 are in fluid communication, thereby the first atomizer 210 can be controlled to work when the user uses the atomizing device, and the second atomizer 220 cannot work.

[0099] Similarly, when the air adjusting ring 371 rotates to the second position, i.e., the third mark 371b of the air adjusting ring 371 corresponds to the second mark 372d, the second atomizing air passage 221 of the second atomizer 220 is communicated with the suction nozzle 700 through the second air hole 112, the second gap 372b and the first air hole 111 in sequence, and the first air hole 111 is shielded by the bottom plate 371a of the air adjusting ring 371, so that the air inlet passage 710, the second atomizing air passage 221 and the suction nozzle 700 are in fluid communication, thereby the second atomizer 220 can work when the user uses the atomizing device, and the first atomizer 210 cannot work.

[0100] When the air adjusting ring 371 rotates to the third position, i.e., the third mark 371b of the air adjusting ring 371 is located between the first mark 372c and the second mark 372d, the bottom plate 371a of the air adjusting ring 371 is away from the first air hole 111 and the second air hole 112, so that the first air hole 111 and the second air hole 112 are both opened, the first atomizing air passage 211 and the second air hole 112 are both communicated with the suction nozzle 700, thereby the first atomizing air passage 211 and the second atomizing air passage 221 are both in fluid communication with the air inlet passage and the suction nozzle 700, thereby the first atomizer 210 and the second atomizer 220 can work simultaneously when the user uses the atomizing device. The principle of triggering the first atomizer 210 and the second atomizer 220 to work is referred to the first embodiment, which will not be described here.

[0101] The first mark 372c, the second mark 372d and the third mark 371b are arranged to prompt the user to select which atomizer to work.

[0102] Please refer to Figure 12In the third embodiment of the present application, the switching switch of the airway control part 300 is a pressing assembly, i.e. the switching switch comprises a first pressing key 361 and a second pressing key 362, the first pressing key 361 corresponds to the first air hole 111, and the second pressing key 362 corresponds to the second air hole 112. Here, the first pressing key 361 and the second pressing key 362 can be linked, i.e. when the user presses the first pressing key 361, the second pressing key 362 is linked to be in the released state, and when the user presses the second pressing key 362, the first pressing key 361 is linked to be in the released state. Of course, the first pressing key 361 and the second pressing key 362 can also be set without linkage. Specifically, the first pressing key 361 and the second pressing key 362 both have a pressing state and a released state, the first pressing key 361 is in the released state to open the first air hole 111, the first pressing key 361 is in the pressing state to close the first air hole 111, the second pressing key 362 is in the released state to open the second air hole 112, and the second pressing key 362 is in the pressing state to close the second air hole 112. When the first pressing key 361 is in the released state and the second pressing key 362 is in the pressing state, the airway control part 300 is in the first state, the switching switch is in the first position, i.e. the first air hole 111 is open, and the second air hole 112 is closed by the second pressing key 362; when the first pressing key 361 is in the pressing state and the second pressing key 362 is in the released state, the airway control part 300 is in the second state, the switching switch is in the second position, i.e. the first air hole 111 is closed by the first pressing key 361, and the second air hole 112 is open; when the first pressing key 361 and the second pressing key 362 are both in the released state, the airway control part 300 is in the third state, and the switching switch is in the third position, i.e. the first air hole 111 and the second air hole 112 are both open. As shown in FIG. 8, the first pressing key 361 and the second pressing key 362 are both in the pressing state, and at this time, the first air hole 111 and the second air hole 112 are both closed. In this embodiment, the user can conveniently switch the state of the airway control part by pressing or releasing the two pressing keys, so as to select the atomizer as needed. Figure 12

[0103] In addition to the above-mentioned mode of directly controlling the airway on-off of the atomization device through the switching switch, in the present application, the switching switch can also drive the switching assembly inside the shell to control the opening and closing of the first air hole and the second air hole, so as to control the airway on-off of the atomization device.

[0104] Specifically, the airway control part comprises a switching switch exposed to the shell, and a switching assembly installed in the shell and connected with the switching switch.

[0105] ​The switching switch is movable relative to the shell under the action of external force, and has a first position, a second position and a third position; when the switching switch is located at the first position, the switching assembly opens the first air hole and closes the second air hole, the air inlet channel, the first atomization air channel and the suction nozzle are in fluid communication, and a user can select the first atomizer to work; when the switching switch is located at the second position, the switching assembly opens the second air hole and closes the first air hole, the air inlet channel, the second atomization air channel and the suction nozzle are in fluid communication, and the user can select the second atomizer to work; when the switching switch is located at the third position, the switching assembly simultaneously opens the first air hole and the second air hole, the air inlet channel, the first atomization air channel and the suction nozzle are in fluid communication, and the air inlet channel, the second atomization air channel and the suction nozzle are in fluid communication, and the user can select the first atomizer and the second atomizer to work simultaneously.

[0106] For details, please refer to Figure 9 and Figure 10 In the fourth embodiment of the present application, the air channel control part 300 includes a toggle switch 310 and a shutter 350; the shell 100 has a top plate 120 and a side plate 140 adjacent to the top plate, the top plate 120 has opposite first and second surfaces (not marked), the first surface is provided with a suction nozzle 700, and the air channel switching area 110 is provided opposite to the second surface. The shutter 350 is movably arranged on the air channel switching area 110, one end of the toggle switch 310 is movably arranged on the side plate 140, and the other end of the toggle switch 310 extends into the shell 100 and is connected with the shutter 350. The toggle switch 310 can be toggled on the side plate 140 and drive the shutter 350 to move on the air channel switching area 110; when the toggle switch 310 is toggled to a first position, the shutter 350 moves to a position where the first air hole 111 is opened and the second air hole 112 is closed, and the air inlet channel, the first atomization air channel 211, the first air hole 111 and the suction nozzle 700 are in fluid communication; when the toggle switch 310 is toggled to a second position as shown in Figure 10 , the shutter 350 moves to a position where the second air hole 112 is opened and the first air hole 111 is closed, and the air inlet channel, the second atomization air channel 221, the second air hole 112 and the suction nozzle 700 are in fluid communication; when the toggle switch 310 is toggled to a third position, the shutter 350 moves to a position where the first air hole and the second air hole are simultaneously opened. In this way, the user can also conveniently realize the free switching of the air channel connectivity of the two atomizers by adjusting the toggle switch 310 on the side plate 140.

[0107] Specifically, the first atomizer 210 and the second atomizer 220 are both in the shape of a long column and are arranged in parallel in the mounting cavity; a limiting groove 131 for accommodating the toggle switch 310 is arranged on the side plate 140, and a limiting protruding rib 132 for limiting the movement range of the shutter 350 is also arranged on the air channel switching area 110. In this embodiment, the toggle switch 310 and the shutter 350 are connected in linkage, and in a transformed embodiment, they can also be integrally formed.

[0108] In this regard, in addition to the aforementioned toggle, slide, and press, etc. modes, the control mode of the airway control portion 300 can also be achieved by rotation, i.e., the airway control portion 300 is a rotating assembly that can be rotated about an axis to a first position, a second position, and a third position; when the rotating assembly is rotated to the first position, the airway control portion 300 is in the first state; when the rotating assembly is rotated to the second position, the airway control portion 300 is in the second state; and when the rotating assembly is rotated to the third position, the airway control portion 300 is in the third state.

[0109] Please refer to Figures 15 to 21 In the fifth embodiment of the present application, the airway control portion 300 includes an external knob 381 outside the housing 100 and an airway knob 382 built in the housing 100, one end of the external knob 381 protrudes out of the housing 100, and the other end of the external knob 381 is connected with the airway knob 382 to drive the airway knob 382 to rotate about an axis; the airway knob 382 is built in the installation cavity and located between the external knob 381 and the control mainboard 600 inside the housing. The first atomizing airway 211 and the airway knob 382 are provided with a first air inlet channel 711, and the second atomizing airway 221 and the airway knob 382 are provided with a second air inlet channel 721.

[0110] Specifically, as shown in Figure 17 and Figure 18 , the airway knob 382 includes a rotating sleeve 382a and a fixed sleeve 382b that are sleeved with each other, the fixed sleeve 382b is provided with a first air hole 111 and a second air hole 112, and the rotating sleeve 382a is provided with an air passage 382e; the fixed sleeve 382b is fixedly connected with the support inside the installation cavity, and the rotating sleeve 382a is connected with the external knob 381 and can rotate relative to the fixed sleeve 382b. When the external knob 381 drives the rotating sleeve 382a to rotate to the first position as shown in Figure 19 , the rotating sleeve 382a is rotated to the air passage 382e to communicate with the first air hole 111 to open the first air hole 111 and close the second air hole 112, and the first air hole 111, the first air inlet channel 711, the first atomizing airway 211, and the suction nozzle 700 are in fluid communication; it should be noted that in this embodiment, the first atomizing airway 211 and the second atomizing airway 221 are both directly communicated with the suction nozzle 700.

[0111] Similarly, when the external knob 381 drives the rotating sleeve 382a to rotate to the second position, the rotating sleeve 382a is rotated to the air passage 382e to communicate with the second air hole 112 to open the second air hole 112 and close the first air hole 111, and the second air hole 112, the second air inlet channel 721, the second atomizing airway 221, and the suction nozzle 700 are in fluid communication

[0112] The external knob 381 drives the rotating sleeve 382a to rotate as shown in FIG. Figure 20 In the third position shown, the rotating sleeve 382a rotates to the ventilation channel 382e and simultaneously connects with the first ventilation hole 111 and the second ventilation hole 112, thereby simultaneously opening the first ventilation hole 111 and the second ventilation hole 112. The first ventilation hole 111, the first air inlet channel 711, the first atomizing air channel 211, and the mouthpiece 700 are in fluid communication, and the second ventilation hole 112, the second air inlet channel 721, the second atomizing air channel 221, and the mouthpiece 700 are in fluid communication. In this way, the user can rotate the external knob 381 exposed on the surface of the housing 100 to drive the internal air channel knob 382 to rotate, thereby switching between different air channel paths of the atomizing device, and can choose to operate a single atomizer alone or two atomizers simultaneously as needed.

[0113] In addition, the external knob 381 drives the rotating sleeve 382a to rotate as shown in FIG. Figure 21 In the other positions shown, the airways of both nebulizers are closed and there is no airflow.

[0114] Of course, the present design is not limited to this. In other embodiments, the rotating assembly may also have other structural designs. For example, the rotating assembly includes a rack (not shown), a rotating gear (not shown) and an airway knob 382. Specifically, the airway knob 382 includes a rotating sleeve 382a and a fixed sleeve 382b that are coupled inside and outside. The fixed sleeve 382b is provided with a first vent hole and a second vent hole, and the rotating sleeve 382a is provided with a ventilation channel 382e; the fixed sleeve 382b is fixedly connected to the bracket inside the mounting cavity, and the rotating sleeve 382a is connected to the rotating gear and can rotate relative to the fixed sleeve 382b; one end of the rack is connected to a button or a toggle switch (not shown) provided on the housing 100, and the other end of the rack is engaged with the rotating gear. The button or toggle switch drives the rack to move and drives the rotating gear to rotate.

[0115] In these two technical solutions involving the airway knob 382, ​​a cam portion 383 is provided at one end of the rotating sleeve 382a facing the control main board 600, and a first spring piece 384a and a second spring piece 384b are provided between the rotating sleeve 382a and the control main board 600. When the rotating sleeve 382a drives the cam portion 383 to rotate to the first position, the cam portion 383 presses the first spring piece 384a so that the feeding point of the first spring piece 384a protruding toward the control main board 600 abuts against the control main board 600. At this time, the rotating sleeve 382a is stuck, indicating that the rotating sleeve 382a is rotated into place, to prompt the user that the external knob 381 has been rotated to the first position.

[0116] When the rotating sleeve 382a drives the cam portion 383 to rotate to the second position, the cam portion 383 abuts against the second elastic sheet 384b, so that the protruding feeding point of the second elastic sheet 384b abuts against the control main plate 600. At this time, the rotating sleeve 382a is clamped, indicating that the rotating sleeve 382a is rotated to the position, so as to prompt the user that the external knob 381 is rotated to the second position.

[0117] In the embodiment, when the rotating sleeve 382a drives the cam portion 383 to rotate to the third position, the feeding points of the first elastic sheet 384a and the second elastic sheet 384b are not in contact with the control main plate 600. In other alternative embodiments, the feeding points of the first elastic sheet 384a and the second elastic sheet 384b can be arranged to abut against the control main plate 600 when the rotating sleeve 382a drives the cam portion 383 to rotate to the third position.

[0118] In addition, compared with the scheme of driving the rotating gear by the rack, the scheme in the fifth embodiment is to directly drive the airway knob 382 to rotate by the external knob 381, without switching through any intermediate component, which can effectively increase the transmission efficiency and reduce the failure rate. When the airway knob 382 rotates, the switching of the airway and the switching of the feeding points of the elastic sheet can be simultaneously realized.

[0119] In the embodiment, the sealing assembly is required to seal the airway, so that the airflow can flow through the pneumatic switch and enter the first atomizing airway 211 and / or the second atomizing airway 221. The sealing is usually performed by using sealing silica gel. Of course, in other embodiments, the sealing silica gel at the pneumatic switch can be removed, and the foam with larger elastic space is used for sealing, so that the control main plate 600 can obtain more displacement space, and the control main plate 600 can be additionally provided with a reinforcing rib for realizing the reinforcement of the plate member and fixed by a screw, thereby being beneficial to the position stability of the control main plate 600. In addition, in the fifth embodiment, the airway knob 382 is preferably made of powder metallurgy. The protruding portion of the elastic sheet 384 is appropriately increased by 1 mm from the airway knob 382, so as to facilitate the deformation of the elastic sheet. Here, the first elastic sheet 384a and the second elastic sheet 384b have the function of limiting the switching position and also have the function of conducting electricity, that is, the elastic sheet can be a metal elastic sheet. The elastic sheet is connected with the control main plate 600, and the actual design can be performed to make the elastic sheet form the on-off control of the electrical contact connection between the control main plate 600 and the first atomizer 210 and the second atomizer 220, so as to make the first atomizer 210 and / or the second atomizer 220 work by being electrified.

[0120] Of course, in addition to the foregoing embodiments, the air passage of the atomization device can be switched by other means. For example, the switching assembly in the air passage control part inside the shell can be an air path switching clutch (not shown) arranged in the sealing assembly, and the external switching switch can be the aforementioned toggle switch, rotary switch, etc. The air path switching clutch is driven by the switching switch and has a first position, a second position and a third position. When the air path switching clutch moves to the first position, the air passage control part is in the first state. When the air path switching clutch moves to the second position, the air passage control part is in the second state. When the air path switching clutch moves to the third position, the air passage control part is in the third state.

[0121] In addition, please refer to Figure 11 In the sixth embodiment of the present application, unlike the foregoing embodiments, the air passage control part 300 is arranged at the bottom of the mouthpiece 700. In one case, the air passage control part 300 can be the bottom of the mouthpiece 700, i.e. the mouthpiece 700 and the air passage control part 300 are integrally arranged, and the mouthpiece 700 is the switching switch. The bottom of the mouthpiece 700 is in sliding connection with the slide rail (not shown) in the air passage switching area 110. In another case, the air passage control part 300 can also be a slider connected to the bottom of the mouthpiece 700, and the slider is in sliding connection with the slide rail in the air passage switching area 110.

[0122] The air passage control part 300 can move along the air passage switching area 110 relative to the shell 100 and has a first position, a second position and a third position. When in the first position, the air passage control part 300 covers the first air hole 111, so that the first atomization air passage 211 communicates with the mouthpiece 700 through the first air hole 111, and the air inlet channel, the first atomization air passage 211 and the mouthpiece 700 are in fluid communication. The user can select the first atomizer 210 to work, while the second air hole 112 is not covered by the mouthpiece 700 and is not opened. The second atomization air passage 221 and the mouthpiece 700 cannot form effective fluid communication, and the second atomizer 220 is not triggered and does not start working. Similarly, when in the second position, the air passage control part 300 covers the second air hole 112, so that the second atomization air passage 221 communicates with the mouthpiece 700 through the second air hole 112. When the user uses the atomization device, the second atomizer 220 works alone. When in the third position, the air passage control part 300 covers the first air hole 111 and the second air hole 112 at the same time, so that the first atomization air passage 211 communicates with the mouthpiece 700 through the first air hole 111, and the second atomization air passage 221 communicates with the mouthpiece 700 through the second air hole 112. When the user uses the atomization device, the first atomizer 210 and the second atomizer 220 work at the same time.

[0123] Specifically as Figure 11As shown in the right side view of FIG. 1, when the suction nozzle 700 slides to the second position, the air passage control part 300 is in the second state, and the second atomizing air passage 221 of the second atomizer 220 is communicated with the suction nozzle 700 through the second air hole 112; as shown in the middle view of FIG. 1, when the suction nozzle 700 slides to the third position, the air passage control part 300 is in the third state, and the air passages of the two atomizers are respectively communicated with the suction nozzle 700 through the first air hole 111 and the second air hole 112. In this way, the user can push and slide the suction nozzle 700 to conveniently switch the two atomizers. Figure 11

[0124] It should be noted that the switch in the present application is not limited to the above-mentioned specific embodiments of the toggle switch, the rotary switch (such as the adjusting ring), and the button switch. For example, the switch is a toggle switch in one embodiment, and it can also be a rotary switch in other modified embodiments.

[0125] The above is only a preferred embodiment of the present application and is not intended to limit the present application. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.​
