Description

Technical Field

[0001] This utility model relates to the field of atomizing device technology, and in particular to a mouthpiece and atomizing device with freely switchable airways. Background Technology

[0002] Existing atomizing devices use single-channel or dual-channel nozzles. Single-channel nozzles have only a single airflow path and a single fuel tank, so they lack airflow adjustment functionality. Dual-channel nozzles have two airflow paths and two fuel tanks, enabling airflow adjustment. However, existing dual-channel nozzles have a limited airflow adjustment mode, which is inconvenient and inaccurate. The airtight structure at the airflow adjustment point is also unstable, making it prone to cross-contamination and leakage, thus affecting the customer experience. Utility Model Content

[0003] To address the shortcomings of existing technologies, this invention provides a mouthpiece and atomizing device with freely switchable airways.

[0004] In a first aspect, this utility model provides a suction nozzle with freely switchable airways, including a suction nozzle and a switching plate. The air outlet of the suction nozzle is connected to a first airway and a second airway through a switching cavity. The switching plate is provided with multiple through holes and is movably disposed within the switching cavity. By adjusting the positions of the multiple through holes between the air outlet, the first airway, and the second airway, multiple positions are formed. In the first position, the air outlet and the second airway are separated by the switching plate, and the air outlet is connected to the first airway through one of the through holes of the switching plate. In the second position, the air outlet is connected to the first airway and the second airway respectively through two corresponding through holes on the switching plate. In the third position, the air outlet and the first airway are separated by the switching plate, and the air outlet is connected to the second airway through one of the through holes of the switching plate.

[0005] In some embodiments, the switching plate is provided with four through holes. In the first position, the air outlet and the second air outlet are separated by the switching plate, and the air outlet is connected to the first air outlet through the first through hole of the switching plate. In the second position, the air outlet is connected to the first air outlet and the second air outlet through the second through hole and the third through hole, respectively. In the third position, the air outlet and the first air outlet are separated by the switching plate, and the air outlet is connected to the second air outlet through the fourth through hole.

[0006] In some embodiments, the switching plate is provided with a partition in the area between the second through hole and the third through hole. In the first position, the partition is located in the second air passage to isolate the air outlet passage from the second air passage. In the third position, the partition is located in the first air passage to isolate the air outlet passage from the first air passage.

[0007] In some embodiments, the switching chamber is provided with a first sealing ring on the air outlet side to seal the gap between the switching plate and the air outlet. The switching chamber is provided with a second sealing ring and a third sealing ring on the first air outlet side and the second air outlet side, respectively. When the switching plate is in the first position, the air outlet, the first through hole and the first air outlet form a first airtight channel through the first sealing ring and the second sealing ring. When the switching plate is in the second position, the air outlet, the second through hole, the first air outlet, the third through hole and the second air outlet form a second airtight channel through the first sealing ring, the second sealing ring and the third sealing ring. When the switching plate is in the third position, the air outlet, the fourth through hole and the second air outlet form a third airtight channel through the first sealing ring and the third sealing ring.

[0008] In some embodiments, a fourth sealing ring is provided between the second and third sealing rings in the switching cavity. When the switching plate is in the first position, the fourth sealing ring seals the outer circumference of the second through hole, and when it is in the third position, the fourth sealing ring seals the outer circumference of the third through hole.

[0009] In some embodiments, the switching plate is provided with multiple positioning slots corresponding to multiple gear positions, and the switching cavity is provided with a positioning block. When the switching plate moves to one of the gear positions, the positioning block engages with the corresponding positioning slot for positioning.

[0010] In some embodiments, the switching plate has an elastic portion on the side near the positioning block, and the positioning groove is formed at the edge of the elastic portion.

[0011] In some embodiments, the switching plate is provided with a lever, the outer wall of the suction nozzle is provided with a toggle groove, and the lever is movably disposed in the toggle groove.

[0012] In some embodiments, the bottom of the suction nozzle is provided with a plurality of magnets that magnetically engage with the host.

[0013] Secondly, this utility model provides an atomizing device, including the mouthpiece with freely switchable airways as described in the first aspect.

[0014] Compared with the prior art, the beneficial effects of this utility model are: by using a switching plate to connect the air outlet with one or both of the first and second air channels, the switching plate can be freely switched between three positions, so that the nozzle can switch between two single air channels and one dual air channel mode, thereby freely adjusting the air according to the usage situation.

[0024] The specific embodiments of this utility model are described with reference to the accompanying drawings.

[0025] refer to Figure 1 The diagram shows the position and structure of the switching plate 2 in three positions of the nozzle with freely switchable airways. Part a of the diagram shows the position of the switching plate 2 in the first position, where only the first through hole 21 of the switching plate 2 is connected to the first airway 4, so that the air outlet 3 is only connected to the first airway 4. Part b of the diagram shows the position of the switching plate 2 in the second position, where the second through hole 22 of the switching plate 2 is connected to the first airway 4 and the third through hole 23 is connected to the second airway 5, so that the air outlet 3 is connected to both the first airway 4 and the second airway 5. Part c of the diagram shows the position of the switching plate 2 in the third position, where only the fourth through hole 24 of the switching plate 2 is connected to the second airway 5, so that the air outlet 3 is only connected to the second airway 5.

[0026] refer to Figures 1 to 5A suction nozzle 1 with freely switchable airways includes a suction nozzle 1 and a switching plate 2. The air outlet 3 of the suction nozzle 1 is connected to a first airway 4 and a second airway 5 through a switching cavity 11. The switching plate 2 is provided with multiple through holes and is movably disposed within the switching cavity 11. Multiple positions are formed by adjusting the positions of the multiple through holes between the air outlet 3, the first airway 4, and the second airway 5. In the first position, the air outlet 3 is separated from the second airway 5 by the switching plate 2 and is connected to the first airway 4 through one of the through holes of the switching plate 2. In the second position, the air outlet 3 is connected to the first airway 4 and the second airway 5 through two corresponding through holes on the switching plate 2. In the third position, the air outlet 3 is separated from the first airway 4 by the switching plate 2 and is connected to the second airway 5 through one of the through holes of the switching plate 2.

[0027] The freely switchable airway nozzle 1 of this application connects the air outlet 3 with one or both of the first airway 4 and the second airway 5 via the switching plate 2. The switching plate 2 is pushed to freely switch between three positions, so that the nozzle 1 can switch between two single airway and one dual airway modes, thereby freely adjusting the air according to the usage.

[0028] To achieve switching between the three modes, in this embodiment, reference is made to... Figure 1 The switching plate 2 is provided with four through holes. In the first position, the air outlet 3 and the second air outlet 5 are separated by the switching plate 2, and are connected to the first air outlet 4 through the first through hole 21 of the switching plate 2. In the second position, the air outlet 3 is connected to the first air outlet 4 and the second air outlet 5 through the second through hole 22 and the third through hole 23, respectively. In the third position, the air outlet 3 and the first air outlet 4 are separated by the switching plate 2, and are connected to the second air outlet 5 through the fourth through hole 24.

[0029] Understandably, the four through holes are spaced apart on the switching plate 2. In the first and second gear positions, the air outlet 3 is connected to the first air passage 4 through the first through hole 21 and the second through hole 22, respectively. In the second and third gear positions, the air outlet 3 is connected to the second air passage 5 through the third through hole 23 and the fourth through hole 24, respectively. The first air passage 4 works in conjunction with the first through hole 21 and the second through hole 22, and the second air passage 5 works in conjunction with the third through hole 23 and the fourth through hole 24. This avoids the first air passage 4 and the second air passage 5 using the same through holes, which would cause cross-contamination of flavors. It also makes it easier to adjust the diameter of the through holes according to the air intake of the first air passage 4 and the second air passage 5, thereby improving the adaptability of the solution.

[0030] To avoid cross-contamination, in this embodiment, reference is made. Figure 1 The switching plate 2 is provided with a partition 25 in the area between the second through hole 22 and the third through hole 23. In the first position, the partition 25 is located in the second air passage 5 to isolate the air outlet 3 from the second air passage 5. In the third position, the partition 25 is located in the first air passage 4 to isolate the air outlet 3 from the first air passage 4.

[0031] Understandably, in the first gear position, the air outlet 3 only needs to be connected to the first air outlet 4, and the partition 25 needs to block the second air outlet 5 so that the air outlet 3 and the second air outlet 5 are not connected. In the second gear position, the air outlet 3 only needs to be connected to the second air outlet 5, and the partition 25 can block the first air outlet 4 so that the air outlet 3 and the first air outlet 4 are not connected, thus avoiding cross-contamination of air.

[0032] To ensure the airtightness of the switching cavity 11, in this embodiment, reference is made to... Figure 3 and Figure 4 The switching chamber 11 is provided with a first sealing ring 13 on the side of the air outlet 3 to seal the gap between the switching plate 2 and the air outlet 3. The switching chamber 11 is provided with a second sealing ring 14 and a third sealing ring 15 on the side of the first air outlet 4 and the side of the second air outlet 5, respectively. When the switching plate 2 is in the first position, the air outlet 3, the first through hole 21 and the first air outlet 4 form a first airtight channel through the first sealing ring 13 and the second sealing ring 14. When the switching plate 2 is in the second position, the air outlet 3, the second through hole 22, the first air outlet 4, the third through hole 23 and the second air outlet 5 form a second airtight channel through the first sealing ring 13, the second sealing ring 14 and the third sealing ring 15. When the switching plate 2 is in the third position, the air outlet 3, the fourth through hole 24 and the second air outlet 5 form a third airtight channel through the first sealing ring 13 and the third sealing ring 15.

[0033] Understandably, the first sealing ring 13 has a larger diameter, ensuring that the corresponding through hole can communicate with the air outlet 3 in all three positions, while also sealing the gap between the switching plate 2 and the air outlet 3. The second sealing ring 14 and the third sealing ring 15 have smaller diameters, respectively responsible for sealing the outer circumference of the first air outlet 4 and the second air outlet 5, ensuring good airtightness of the airtight channels during switching and preventing cross-contamination and mutual interference between the first air outlet 4 and the second air outlet 5.

[0034] To further improve the airtightness of the airtight channel, in this embodiment, reference is made to... Figure 3 The switching chamber 11 is provided with a fourth sealing ring 16 between the second sealing ring 14 and the third sealing ring 15. When the switching plate 2 is in the first position, the fourth sealing ring 16 seals the outer circumference of the second through hole 22. When it is in the third position, the fourth sealing ring 16 seals the outer circumference of the third through hole 23.

[0035] Understandably, the fourth sealing ring 16 seals the second through hole 22 in the first position to prevent the airflow of the first airtight channel from leaking out through the second through hole 22, and the fourth sealing ring 16 seals the third through hole 23 in the third position to prevent the airflow of the third airtight channel from leaking out through the third through hole 23, thereby improving airtightness.

[0036] To facilitate accurate gear shifting for users, in this embodiment, reference is made to... Figure 1 and Figure 4 The switching plate 2 is provided with three positioning slots 27 corresponding to the three gear positions, and the switching cavity 11 is provided with a positioning block 12. When the switching plate 2 moves to one of the gear positions, the positioning block 12 engages with the corresponding positioning slot 27 for positioning.

[0037] It is understandable that the positioning block 12 protrudes towards the switching plate 2. When the switching plate 2 is pushed in the switching cavity 11, the positioning block 12 will slide along the edge of the switching plate 2. When the positioning block 12 slides to the positioning groove 27, the positioning block 12 will be engaged in the positioning groove 27, giving the user feedback so that the user knows that the switching plate 2 has been pushed into place. When the positioning block 12 is engaged in the positioning groove 27, the positioning block 12 will have a certain locking force to prevent the switching plate 2 from easily coming loose from the gear position.

[0038] To prevent the positioning block 12 from jamming the switching plate 2, in this embodiment, reference is made to... Figure 1 The switching plate 2 has an elastic part 26 on the side near the positioning block 12, and the positioning groove 27 is opened on the edge of the elastic part 26.

[0039] It is understandable that there is a shaped hole 28 between the elastic part 26 and the main body of the switching plate 2. When the user pushes the switching plate 2, the positioning block 12 will press against the positioning groove 27, causing the elastic part 26 to bend and deform in the direction of the shaped hole 28 (the degree of deformation is low), so that the positioning block 12 and the positioning groove 27 will not be squeezed too tightly, ensuring that the positioning block 12 can disengage from the positioning groove 27 to realize the gear switching.

[0040] To facilitate the user in pushing the switchboard 2, in this embodiment, refer to Figure 1 and Figure 2 The switching plate 2 is equipped with a lever 29, and the outer wall of the suction nozzle 1 is equipped with a toggle groove 17. The lever 29 is movably disposed in the toggle groove 17.

[0041] It should be further explained that a limiting plate 20 is provided on one side of the lever 29 of the switching plate 2. The limiting plate 20 moves along the sliding groove 19 on the inner wall of the switching cavity 11 to limit the movement path of the switching plate 2 and ensure that the switching plate 2 can move stably in the switching cavity 11.

[0042] It is understandable that the main body of the switching plate 2 is inside the switching cavity 11. The exposed lever 29 allows the user to easily operate the switching plate 2. The moving area of ​​the lever 29 is limited by the toggle groove 17 to avoid excessive pushing of the switching plate 2 and to prevent damage to the switching plate 2.

[0043] To facilitate the installation of the suction nozzle 1, in this embodiment, refer to Figure 5 The bottom of the suction nozzle 1 is equipped with multiple magnets 18 that magnetically connect with the main unit.

[0044] Understandably, the nozzle 1 can be quickly connected to the atomizing device main unit via the magnet 18 at the bottom, making it convenient to replace the nozzle 1 and improving ease of use.

[0045] The freely switchable airway mouthpiece 1 of this application embodiment can be well adapted to electronic atomization devices that use multiple flavored e-liquid cartridges, and can also be applied to medical atomization devices that require precise control of the drug-air mixing ratio. It can select single airway or dual airway mode, and users can choose single airway or dual airway intake according to the actual situation, which greatly enhances the user experience and adapts to a variety of usage environments.

[0046] This application embodiment also provides an atomizing device, including a main unit and the above-mentioned freely switchable airway nozzle 1, wherein the nozzle 1 is magnetically connected to the main unit via a magnet 18.

[0047] The atomizing device of this application embodiment can support single-channel use and dual-channel mixing through the freely switchable airway nozzle 1. The switching plate 2 can quickly switch modes, expanding the usage modes of the atomizing device. For example, different concentrations and components of aerosols can be selected according to needs. The switching operation is convenient. With clear gear feedback, misoperation is avoided, and a compact and reliable three-gear airway switching function is achieved.

[0048] The above does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
