Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0026] Please see Figure 5 and Figure 6The airway switch structure 10 includes an airway 101, a moving part 102, a lead screw 103, and a driving part 104. The airway 101 has at least two ports, namely an inlet end and an outlet end, and the airflow in the airway 101 flows from the inlet end to the outlet end. A blocking part 1022 is disposed at the port of the airway 101 and is fixedly connected to the connecting part 1021. In this embodiment, the blocking part 1022 and the connecting part 1021 are fixedly connected by screws, and can move along the lead screw 1031 and has a closed position for closing the port of the airway 101 and an open position for opening the port of the airway 101, thereby realizing the airflow switch in the airway 101. The shielding part 1022 has multiple vents for gas to flow from inside the airway 101 to outside the airway 101 or from outside the airway 101 to inside the airway 101. The specific location depends on whether the shielding part 1022 is located at the inlet or outlet of the airway 101. In this embodiment, the shielding part 1022 is located at the inlet of the airway 101, and the gas at the vents flows from outside the airway 101 to inside the airway 101. In this embodiment, there are two airways 101, designated as the first airway and the second airway, and the airflow within the two airways 101 does not interfere with each other. The driving member 104 is connected to the lead screw 1031 to drive the lead screw 1031 to rotate, further driving the moving member 102 to switch between a closed position and an open position.

[0027] Please see Figure 4 , Figure 5 as well as Figure 6The moving part 102 includes a connecting part 1021 and a blocking part 1022. A screw 1031 is threadedly connected to the connecting part 1021, and the blocking part 1022 is fixedly connected to the connecting part 1021. The blocking part 1022 is used to close or open the air passage 101 port. More preferably, the moving part 102 has at least three working positions: when the moving part 102 is in the first position, the first air passage port is open and the second air passage port is closed, with only gas in the first air passage flowing into the housing 20; when the moving part 102 is in the second position, the first air passage port is closed and the second air passage port is open, with only gas in the second air passage flowing into the housing 20; this achieves switching between a single air passage, i.e., the first air passage or the second air passage. When the moving part 102 is in the third position, both the first and second air passage ports are open, and gas in both the first and second air passages can flow into the housing 20. In addition, the moving part 102 can also be in the fourth position, at which time both blocking parts 1022 are in a closed position, and the gas in the two air passages 101 cannot flow into the housing 20. It should be noted that one moving part 102 can complete the above functions. In this embodiment, preferably, two moving parts 102 are provided, corresponding to the first air passage and the second air passage respectively, so as to control the opening and closing of the first air passage and the second air passage respectively. That is, the blocking part 1022 and the connecting part 1021 are set in two groups along the lead screw 1031, corresponding to the two air passages 101 respectively. More preferably, two lead screws 1031 are arranged in parallel, and two connecting parts 1021 are fixedly connected to both ends of the blocking part 1022, and the two connecting parts are threaded to the two lead screws 1031 respectively. The end faces of the two connecting parts 1021 connected to the same blocking part 1022 are flush with the blocking part 1022, thereby restricting the rotation of the connecting parts 1021. When the lead screw 1031 rotates, the connecting parts 1021 can be driven to move along the lead screw 1031. Furthermore, the same driving member 104 connects the two lead screws 1031 and drives the two lead screws 1031 simultaneously, so that the two lead screws 1031 move synchronously.

[0028] Please see Figure 3 and Figure 4The airway switch structure 10 also includes a base bracket 105, which has a first mounting groove 1051. The two ends of the lead screw 1031 abut against the two sides of the first mounting groove 1051, thereby restricting the axial movement of the lead screw 1031. It should be noted that when there is only one lead screw 1031, the connecting part 1021 is disposed in the first mounting groove 1051, and the two sides of the connecting part 1021 correspond to and abut against the two sides of the first mounting groove 1051, thereby restricting the rotation of the connecting part 1021. Preferably, the base bracket 105 has a second mounting groove 1052, and the airway switch structure 10 also includes a sealing elastic element 106, which is disposed in the second mounting groove 1052. The sealing elastic element 106 communicates with the airway 101, and the blocking part 1022 abuts against the sealing elastic element 106. The sealing elastic element 106 is made of elastic material, which can enhance the airtightness between the airway 101 and the blocking part 1022.

[0029] Please see Figure 2 , Figure 3 as well as Figure 5 Specifically, the airway switch structure 10 also includes a control component 107, which is communicatively connected to the drive unit 104 to control the operation of the drive unit 104, further driving the connection part 1021 to switch between the closed and open positions. Furthermore, the control component 107 includes an operating element 1071, a power supply element 1072, and a circuit board 1073. The circuit board 1073 is electrically connected to the operating element 1071, the power supply element 1072, and the drive unit 104 respectively. After operating the operating element 1071, a signal is sent to the circuit board 1073, which controls the drive unit 104 to rotate the lead screw 1031. The airway 101 is switched using electrically driven air regulating plates. Compared to the airway switch structure 10 using a traditional toggle switch, this reduces the number of mating parts and openings, resulting in a more complete product appearance.

[0030] Please refer to the figure. Figure 1 , Figure 2 as well as Figure 3This application also provides an aerosol atomizing device, including the aforementioned airway switch structure 10 and a housing 20. A nozzle 201 may be provided on the top of the housing 20, allowing the user to perform a suction action at the nozzle 201. A base support 105 is located at the end of the housing 20 away from the nozzle 201. The aerosol atomizing device has two independent atomization systems. The corresponding atomization system is activated based on the opening and closing status of the two airways 101. After activation, the corresponding atomization system atomizes the aerosol generating matrix. The atomized aerosol is then drawn out from the nozzle 201, thus allowing adjustment of the aerosol volume. Furthermore, the housing 20 stores two aerosol generating matrices of different flavors. These two aerosol generating matrices correspond to the two independent atomization systems. The corresponding atomization system is activated based on the opening and closing status of the two airways 101, and the corresponding flavor of the aerosol generating matrix is ​​atomized accordingly, thereby enabling switching between different flavors of aerosol within the same aerosol atomizing device.

[0031] Furthermore, the housing 20 includes an outer shell 202 and an inner shell 203, and the base bracket 105 is installed on the bottom of the outer shell 202 by a snap-fit ​​connection. A suction nozzle 201 is provided at the top center of the outer shell 202. The inner shell 203 is provided above the mounting bracket 40 of the outer shell 202. The inner shell 203 has two liquid storage chambers arranged symmetrically on the left and right sides. The liquid storage chambers on the left and right sides respectively store aerosol generating matrix. In this embodiment, liquid storage cotton 30 is placed in the liquid storage chamber, and the liquid storage cotton 30 is soaked in liquid aerosol generating matrix; furthermore, the liquid storage cotton 30 on the left and right sides can respectively store aerosol generating matrix with different flavors.

[0032] Please see Figure 2 The aerosol atomizing device also includes two atomizing components 50, which are arranged symmetrically on the left and right sides within the housing 20. Each atomizing component 50 includes a guide tube 501, a heating element 502, and a liquid guiding element 503. The guide tube 501 is constructed to form a first airflow channel 5011, and the nozzle 201 has a second airflow channel 2011 connecting the first airflow channel 5011 to the outside of the aerosol generating device. The guide tube 501 passes through the liquid storage cotton 30. The heating element 502 is disposed on the guide tube 501 and is provided with an electrode 5021. One end of the liquid guiding element 503 is connected to the heating element 502, and the other end of the liquid guiding element 503 extends into the liquid storage cotton 30 to conduct the aerosol generating matrix of the liquid storage cotton 30 to the heating element 502. The aerosol generating matrix is ​​heated by the heating element 502, atomized, and forms an aerosol. The aerosol flows through the first airflow channel 5011 and the second airflow channel 2011 to the nozzle 201, and finally flows out of the aerosol generating device.

[0033] Furthermore, the aerosol atomizing device also includes a mounting bracket 40, within which an airway 101 is formed. A power supply unit 1072 is disposed within the mounting bracket 40. The top of the mounting bracket 40 has two independent mounting cavities 401. Each mounting cavity 401 has an air outlet 402 at a corner corresponding to one of the lower airways 101, allowing the airway 101 to communicate with the corresponding first airflow channel 5011 through the mounting cavity 401. A first sealing silicone 60 is provided between the liquid storage cotton 30 and the mounting bracket 40, sealingly connecting the first sealing silicone 60 to the liquid storage cotton 30. A portion of the first sealing silicone 60 extends into the mounting cavity 401 at the top of the mounting bracket 40 and seals against the inner wall of the mounting cavity 401. The bottom end of the guide tube 501 of the atomizing component 50 passes through the first sealing silicone 60 and extends into the mounting cavity 401. The inner shell 203 is provided with a second sealing silicone 70 on the top, and the second sealing silicone 70 is covered with a mounting base 80. The mounting base 80 and the second sealing silicone 70 are provided with through holes at corresponding positions so that the first airflow channel 5011 formed by the guide tube 501 is connected to the second airflow channel 2011 of the suction nozzle 201.

[0034] In summary, this application drives the lead screw to rotate via a drive component, which further moves and switches the blocking part between the closed and open positions, thereby opening or closing the air passage. The drive component replaces the user's fingers to complete the air passage switching operation, solving the problem of different difficulties caused by fingers and nails when the user directly operates the physical mechanical key, and avoiding the risk of key jamming.
