[0008] In some embodiments, the length direction of the second set of fixed magnets and the length direction of the second set of movable magnets are both perpendicular to the line connecting the axes of the first and second air passages.

[0009] In some embodiments, a sealing ring is provided on the inner side of the air outlet, and a sealing element is provided on the outer circumference of the first air passage and the second air passage of the housing.

[0012] In some embodiments, the outer side wall of the housing has a stop hole, and the switching plate extends a lever toward the stop hole, the lever reciprocating along the stop hole.

[0013] In some embodiments, the switching plate has a limiting plate at the root of the lever, the limiting plate being movably disposed in a limiting groove inside the housing, and the area of ​​the limiting plate being larger than the area of ​​the stop hole.

[0028] The specific embodiments of this utility model are described with reference to the accompanying drawings.

[0029] refer to Figures 1 to 5 A suction nozzle 1 with magnetic locking for switching air passages includes a housing 2 with an air outlet 21 at each end and two air passages at the other end. A switching plate 6 is movably disposed inside the housing 2. The switching plate 6 is used to switch the connection state between the two air passages and the air outlet 21. A magnetic locking structure is provided between the switching plate 6 and the housing 2. The magnetic locking structure is disposed along the moving path of the switching plate 6. The magnetic locking structure includes at least two sets of fixed magnets and a corresponding number of movable magnets. At least two sets of fixed magnets are fixed at corresponding positions inside the housing 2. The movable magnets are fixed on the switching plate 6. The movable magnets that move with the switching plate 6 between positions are magnetically engaged with the corresponding fixed magnets to position the switching plate 6 at the corresponding position.

[0030] The magnetic chock structure includes three sets of fixed magnets and three sets of movable magnets. These three sets of fixed magnets and three sets of movable magnets are staggered along the moving path of the switching plate 6 to form three chocks. The switching plate 6 switches between three connection states between the two air passages and the air outlet 21 through these three chocks. In conjunction with the two oil tanks of the main unit 7, it can produce three different concentrations and flavors of aerosol.

[0031] It should be further explained that, in order to improve airtightness, a sealing ring 24 is provided on the inner side of the air outlet 21, and a sealing element 25 is provided on the outer periphery of the first air passage 22 and the second air passage 23 of the housing 2. The two sides of the switching plate 6 cooperate with the sealing ring 24 and the sealing element 25 respectively. The switching plate 6 is provided with multiple through holes. When the switching plate 6 is in the corresponding position, the first air passage 22 or the second air passage 23, or the first air passage 22 and the second air passage 23, are connected to the air outlet 21 through the corresponding through holes. The housing 2 and the switching plate 6 are made of hard plastic, while the sealing ring 24 and the sealing element 25 of the air outlet 21 are made of soft plastic. The switching plate 6 is pressed tightly against the sealing element 25 by the magnetic force of the fixed magnet and the movable magnet, so that the switching plate 6 has good airtightness with the two air passages and avoids air leakage at the gap between the air passages and the switching plate 6.

[0032] To provide clear gear feedback, in this embodiment, reference is made to... Figures 1 to 5 The housing 2 is provided with a first air passage 22 and a second air passage 23. The first air passage 22 and the second air passage 23 are arranged side by side. Among the three sets of fixed magnets, the second set of fixed magnets 32 is located at the center point between the first air passage 22 and the second air passage 23. The first set of fixed magnets 31 and the second set of fixed magnets 32 are symmetrically arranged on both sides of the first air passage 22 and the second air passage 23. The vertical distance between two adjacent sets of fixed magnets is greater than the vertical distance between two adjacent sets of movable magnets.

[0033] It should be further explained that the first group of fixed magnets 31, the third group of fixed magnets 33, the first group of movable magnets 41, and the third group of movable magnets each include a long strip magnet 51 and a round magnet 52. These long strip magnets 51 are parallel to the moving path of the switching plate 6. The second group of fixed magnets 32 and the second group of movable magnets 42 each have only one long strip magnet 51, which is perpendicular to the moving path of the switching plate 6. The first group of fixed magnets 31 and the third group of fixed magnets 33 are arranged on the same straight line, while the second group of fixed magnets 32 is arranged on a different straight line. At the same time, the first group of movable magnets 41 and the third group of movable magnets 43 are on the same straight line. The first set of movable magnets 42 moves along one straight line, while the second set of movable magnets 42 moves along another straight line. This ensures that the second set of movable magnets 42 will not be magnetically attracted to the first set of fixed magnets 31 or the third set of fixed magnets 33. The distance between the first set of fixed magnets 31 and the third set of fixed magnets 33 is greater than the moving distance of the switching plate 6. This ensures that the first set of movable magnets 41 will not be magnetically attracted to the third set of fixed magnets 33, and the third set of movable magnets 43 will not be magnetically attracted to the first set of fixed magnets 31. It can be understood that by setting the magnet positions in the above staggered manner, the pairing relationship between the three sets of fixed magnets and the three sets of movable magnets is unique, forming a stable gear shift feel and providing the user with clear gear shift feedback.

[0034] To facilitate user switching between the three gears, in this embodiment, reference is made to... Figures 1 to 5 The length direction of the second set of fixed magnets 32 and the length direction of the second set of movable magnets 42 are both perpendicular to the line connecting the axes of the first air passage 22 and the second air passage 23.

[0035] Understandably, under the condition of satisfying airtightness, the smaller the distance between the two air channels, the smaller the distance the switching plate 6 moves. The second set of fixed magnets 32 is vertically set in the middle of the two air channels, so that the first set of fixed magnets 31 has a large enough volume to ensure that the first set of fixed magnets 31 and the second set of movable magnets 42 have sufficient magnetic force. At the same time, it can also ensure that the distance between the two air channels is relatively small, thereby reducing the moving distance of the switching plate 6 and also preventing the nozzle 1 from being too large.

[0036] To prevent cross-contamination, in this embodiment, reference is made to... Figures 1 to 5The switching plate 6 has multiple through holes, including a first through hole 61, a second through hole 62, a third through hole 63, and a fourth through hole 64. A second set of movable magnets 42 is disposed between the second through hole 62 and the third through hole 63. When the switching plate 6 is in the first position, the first air passage 22 is connected to the air outlet 21 through the first through hole 61, and the second air passage 23 is separated from the air outlet 21 by the second set of movable magnets 42. When the switching plate 6 is in the second position, the first air passage 22 and the second air passage 23 are connected to the air outlet 21 through the second through hole 62 and the third through hole 63, respectively. When the switching plate 6 is in the third position, the second air passage 23 is connected to the air outlet 21 through the fourth through hole 64, and the first air passage 22 is separated from the air outlet 21 by the second set of movable magnets 42.

[0037] Understandably, the first through hole 61 and the second through hole 62 only cooperate with the first air passage 22, and the third through hole 63 and the fourth through hole 64 only cooperate with the second air passage 23, so as to avoid the cross-contamination of odors between the through holes. In the first and third positions, the second movable magnet blocks the second air passage 23 and the first air passage 22 respectively to prevent cross-contamination of odors.

[0038] To facilitate the docking of the suction nozzle 1 with the main unit 7, in this embodiment, refer to... Figures 1 to 5 The end face of the housing 2 that connects with the host 7 is provided with multiple alignment magnets 28, which are staggered with three sets of fixed magnets.

[0039] It is understandable that the positioning magnet 28 can be magnetically positioned with the docking magnet 71 on the host 7, which facilitates the docking of the nozzle 1 with the host 7. Within the limited space of the nozzle 1, the positioning magnet 28 is staggered between the fixed magnets. One of the positioning magnets 28, which is between the first set of fixed magnets 31 and the third set of fixed magnets 33, is magnetically attracted with the third set of movable magnets 43 and the first set of movable magnets 41 respectively in the first and third positions, further ensuring that the switching plate 6 can be stably pressed on the sealing element 25.

[0040] To facilitate user operation of the switchboard 6, in this embodiment, refer to Figures 1 to 5 The outer wall of the housing 2 is provided with a stop hole 26, and the switching plate 6 extends a lever 65 to the stop hole 26. The lever 65 moves back and forth along the stop hole 26.

[0041] Understandably, the lever 65 protrudes above the housing 2, allowing the user's fingers to easily push the lever 65, enabling the lever 65 to move back and forth along the gear hole 26, facilitating the user's operation of the switching plate 6.

[0042] In order to ensure that the switching plate 6 can move stably within the housing 2, in this embodiment, reference is made to... Figures 1 to 5The switching plate 6 has a limiting plate 66 at the root of the lever 65. The limiting plate 66 is movably disposed in the limiting groove 27 inside the housing 2. The area of ​​the limiting plate 66 is larger than the area of ​​the stop hole 26.

[0043] It is understandable that the upper and lower sides of the switching plate 6 are limited by the sealing element 25 and the sealing ring 24. The limiting plate 66 is perpendicular to the switching plate 6. Through the cooperation of the limiting plate 66 and the limiting groove 27, the switching plate 6 can only move back and forth in a straight line along the direction of the limiting groove 27, so that the switching plate 6 has only one degree of freedom, ensuring that the switching plate 6 can move stably in the housing 2.

[0044] refer to Figures 1 to 5 This application embodiment also provides an atomizing device, including a main unit 7 and a nozzle 1. The nozzle 1 is magnetically positioned with the main unit 7 by a positioning magnet 28. The nozzle 1 is the above-mentioned magnetically locked airway switching nozzle 1.

[0045] The main unit 7 is equipped with an oil tank, a battery, and an atomizing device. The two oil tanks supply oil to the atomizing device, and the battery powers the atomizing device. When the switch plate 6 is moved to the corresponding position, the corresponding atomizing device atomizes the e-liquid or medicine and delivers it to the mouthpiece 1 through two air channels. The three positions provide three different concentrations and flavors of aerosol.

[0046] 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.
