Description

Technical Field

[0001] This application belongs to the field of electronic atomization equipment technology, and more specifically, relates to an electronic atomization device. Background Technology

[0002] Electronic atomizing devices are appliances that atomize an aerosol matrix to form an aerosol. Some electronic atomizing devices have a function to adjust the draw resistance, i.e., they are equipped with an air regulating component. However, the air regulating plate in these components is relatively large. When the air regulating component is moved to the closed position, the air regulating knob is located in the middle of the air inlet of the housing, making the on / off indication weak and causing inconvenience in draw resistance adjustment. To improve the on / off indication, some electronic atomizing devices have two holes in the bottom of the housing. One hole is used to accommodate the air regulating knob, and the other hole forms the air inlet. However, having multiple holes in the bottom of the housing significantly affects the appearance of the product. Utility Model Content

[0003] The purpose of this application is to provide an electronic atomizing device with strong indication of gas adjustment on / off and simple structure.

[0004] To achieve the above objectives, the technical solution adopted in this application is: to provide an electronic atomizing device, comprising:

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0040] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0041] Please refer to the following: Figures 1 to 3 The electronic atomizing device provided in this application embodiment will now be described. The electronic atomizing device includes a housing 10, and an atomizing component 30, an elastic sealing member 40, and an air regulating component 20 disposed within the housing 10. The housing 10 has an air inlet 120. The air regulating component 20 includes an air regulating plate 21 and a knob 22 connected together. The air regulating plate 21 and the knob 22 are integrally formed. The side of the knob 22 facing away from the air regulating plate 21 has an anti-slip structure to facilitate operation by finger operation. The air regulating plate 21 is slidably disposed within the housing 10 and can move back and forth linearly relative to the housing 10. The knob 22 is located at the air inlet 120. The air regulating component 20 can move back and forth between a first position and a second position relative to the housing 10.

[0042] See Figures 2 to 4 The air regulating plate 21 has air inlets 210, with at least two inlets 210, and the number of inlets 210 can be increased as needed. When the air regulating component 20 moves to the first position, the toggle switch 22 is located at one end of the air inlet 120, and the air inlets 210 are completely blocked by the housing 10. This enhances the indicative nature of the air regulating component 20 being closed, allowing the user to clearly know the current adjustment status of the air regulating component 20 without having to slide it left and right, thus improving the convenience of adjustment. Simultaneously, the position of the air inlets 210 is closer to the toggle switch 22, resulting in a smaller overall length of the air regulating component 20, reducing space occupation and making the internal structure more compact. (See reference...) Figure 4 When the air regulating component 20 moves to the second position, the air inlet 210 communicates with the air inlet 120. Specifically, the air regulating plate 21 is slidably connected to the housing 10. By sliding the air regulating plate 21, the number of air inlets 210 communicating can be adjusted, thereby changing the suction resistance of the air inlet 120. The housing 10 has only one air inlet 120, which is simple in structure and reduces the number of openings on the housing 10, thereby reducing the impact on the appearance of the product, making the overall appearance of the product cleaner and improving the aesthetics of the product. In this embodiment, multiple air inlets 210 are provided. When the air regulating plate 21 slides to the second position, the toggle 22 moves to the other end of the air inlet 120, and all air inlets 210 communicate with the air inlet 120.

[0043] The atomizing assembly 30 is provided with an airflow channel 301, and an elastic seal 40 is sealed on the bottom surface of the atomizing assembly 30. The elastic seal 40 may be, but is not limited to, using sealing silicone. The elastic seal 40 is provided with an air inlet chamber 41 that communicates with the airflow channel 301. The air regulating plate 21 is in sealing contact with the elastic seal 40, thereby improving the sealing performance and increasing the airflow sensing sensitivity of the electronic atomizing device. When the air regulating assembly 20 moves to the first position, the air inlet 210 and the air inlet chamber 41 are closed, and at this time, the airflow channel 301 and the air inlet 120 are closed. When the air regulating assembly 20 moves to the second position, the air inlet 210 and the air inlet chamber 41 are connected, and the airflow channel 301 and the air inlet 120 are connected.

[0044] Compared with the prior art, the electronic atomizing device provided in this application has an air regulating plate 21 slidably disposed inside the housing 10 of the air regulating component 20. When the air regulating plate 21 is adjusted and moved to the first position, the knob 22 moves to one end of the air inlet 120 of the housing 10, and the air inlet 210 on the air regulating plate 21 is completely blocked by the housing 10, which enhances the indicativeness of the opening and closing of the air regulating component 20. The user can know the current adjustment status without having to slide back and forth to adjust, thus bringing convenience to the user's adjustment and use. When the air regulating component 20 is moved to the second position, the air inlet 210 and the air inlet 120 are connected, thereby realizing the adjustment of the suction resistance. The housing 10 only has one air inlet 120, which reduces the impact of the opening on the product appearance, and the overall appearance of the product is cleaner and more beautiful.

[0045] See Figures 1 to 3 The housing 10 includes an outer shell 11 and a bottom cover 12 connected together. An air inlet 120 is formed on the bottom surface of the bottom cover 12, which is attached to the bottom of the outer shell 11 by a snap-fit ​​connection. A mouthpiece 13 is provided on the top of the outer shell 11. A lanyard hook 18 is provided at the top and bottom of one side of the outer shell 11, allowing for easy attachment and carrying of the electronic atomizing device. A display screen is also provided on the other side of the outer shell 11, displaying product parameters and usage status information of the electronic atomizing device.

[0046] The outer casing 11 contains a liquid storage chamber 19, in which a liquid storage cotton 190 is placed, and the liquid storage cotton 190 is impregnated with a liquid aerosol generating matrix. The atomizing assembly 30 includes a guide tube 31, a heating element 32, and a liquid guiding element 33. The guide tube 31 is constructed to form an airflow channel 301, and the guide tube 31 passes through the liquid storage cotton 190. The heating element 32 is disposed on the guide tube 31 and has a first electrode. One end of the liquid guiding element 33 is connected to the heating element 32, and the other end of the liquid guiding element 33 extends into the liquid storage cotton 190 to conduct the aerosol generating matrix of the liquid storage cotton 190 to the heating element 32. The aerosol generating matrix is ​​heated by the heating element 32, atomizes, and forms an aerosol. The aerosol flows through the airflow channel 301 to the mouthpiece 13 and finally flows out of the electronic atomizing device.

[0047] See Figure 5 , Figure 9 A bracket 60 is detachably connected inside the bottom cover 12, and the bracket 60 can be assembled with the bottom cover 12 by a snap-fit ​​connection. The bottom surface of the bracket 60 is provided with a groove 61 that slides in connection with the air regulating plate 21, and the elastic seal 40 is at least partially housed in the bracket 60. In this embodiment, most of the elastic seal 40 is housed in the bracket 60 and is arranged horizontally.

[0048] See Figure 3 , Figures 5 to 8 The upper end of the liquid storage chamber 19 is provided with an upper sealing silicone 14, and the lower end of the liquid storage chamber 19 is provided with a lower sealing silicone 16. An upper absorbent cotton 15 is provided above the upper sealing silicone 14, and a lower absorbent cotton 17 is provided below the lower sealing silicone 16. The lower sealing silicone 16 has a through-hole 160. A cavity 44 is formed between the lower sealing silicone 16 and the elastic sealing element 40. The bottom end of the guide tube 31 of the atomizing assembly 30 passes through the lower sealing silicone 16 and extends into the cavity 44. The airflow channel 301 communicates with the cavity 44. Specifically, the bottom surface of the lower sealing silicone 16 is provided with a first thin-walled structure 161, which forms a roughly annular first receiving cavity. The top surface of the elastic sealing member 40 is provided with a second thin-walled structure 43, which forms a second receiving cavity 430. The lower absorbent cotton 17 is placed in the second receiving cavity 430 to absorb condensate. The first thin-walled structure 161 is sleeved on the outer periphery of the second thin-walled structure 43 and is in sealing contact with the second thin-walled structure 43. In this way, the lower sealing silicone 16 and the elastic sealing member 40 form a cavity 44.

[0049] Please see Figures 8 to 10A cavity 220 is formed by hollowing out one side wall of the lever 22 in the width direction. When the air regulating component 20 moves to the first position, the lever 22 is directly opposite the air inlet end of the air inlet cavity 41. That is, by reducing the amount of adhesive on the side of the lever 22, the size of the air regulating plate 21 can be reduced, while ensuring that the contact area between the air regulating plate 21 and the elastic seal 40 is a flat plane. The air regulating plate 21 is always in contact with the elastic seal 40 when sliding back and forth. When the air regulating plate 21 slides to the first position, the contact area between the elastic seal 40 and the air regulating plate 21 must be a closed flat plane to ensure no air leakage. In order to ensure that there is no shrinkage during injection molding, the traditional method is to reduce the amount of adhesive on the back of the lever 22. To ensure that the contact surface between the air regulating plate 21 and the elastic seal 40 is a flat plane, the lever 22 can only move to one side in the width direction of the air regulating plate 21, thus avoiding the air inlet end at the bottom of the elastic seal 40. Therefore, the air regulating plate 21 must be made larger, that is, the width of the air regulating plate 21 is larger. In this embodiment, the contact point between the air regulating plate 21 and the elastic seal 40 is a flat surface by reducing the adhesive on the side of the toggle 22. In this way, the toggle 22 does not need to avoid the air inlet end at the bottom of the elastic seal 40. That is, the toggle 22 can be set in the middle position in the width direction of the air regulating plate 21, and the width of the air regulating plate 21 does not need to be increased. This makes the internal structure of the housing 10 more compact.

[0050] Furthermore, the cavity 220 extends to the air regulating plate 21, meaning that the corresponding side of the air regulating plate 21 also has a hollowed-out portion. The hollowed-out portions on the same side of the air regulating plate 21 and the toggle 22 together form the cavity 220. The extension of the cavity 220 at the bottom of the toggle 22 to the air regulating plate 21 allows for a greater reduction in the amount of adhesive on the side of the toggle 22, further ensuring that the area where the air regulating plate 21 contacts the elastic seal 40 is planar.

[0051] Please see Figure 3 , Figure 8 and Figure 9 The housing 10 contains a power supply component 50 and a circuit board 51 for electrical connection. The circuit board 51 is horizontally arranged in the bracket 60, and the airflow sensing component 52 is fixed to the top surface of the circuit board 51. The bottom surface of the elastic seal 40 abuts against the circuit board 51. The circuit board 51 has a second electrode 510, which extends through the elastic seal 40 into the cavity 44 and contacts the first electrode, thus electrically connecting to the corresponding atomizing component 30. The airflow sensing component 52 responds to changes in air pressure within the sensing cavity 44, triggering the control circuit to start the corresponding heating element 32, generating aerosol for inhalation. The circuit board 51 has a charging interface 512, and through holes for the charging interface 512 are opened at corresponding positions on the bracket 60 and the bottom cover 12.

[0052] See Figure 6 , Figure 13 and Figure 14The bottom surface of the elastic seal 40 has a vertically protruding hollow extension section 42, which has a cavity extending through the top and bottom. The open end at the bottom of the extension section 42 forms the air intake end of the air intake cavity 41, and the extension section 42 is in sealing contact with the top surface of the air regulating plate 21. In other words, the second receiving cavity 430 formed by the cavity of the extension section 42 and the second thin-walled structure 43 forms the air intake cavity 41, and the elastic seal 40 is in elastic sealing contact with the air regulating plate 21 through the extension section 42.

[0053] The outer peripheral wall of the extension section 42 is provided with an annular groove 420, and the circuit board 51 is provided with a plug hole 511 suitable for insertion of the extension section 42. The extension section 42 is snapped onto the circuit board 51 through the cooperation of the annular groove 420 and the plug hole 511. Specifically, the extension section 42 is provided with an annular groove 420 at the connection of the bottom surface of the elastic seal 40. After the extension section 42 passes through the plug hole 511 of the circuit board 51, it is snapped onto the circuit board 51 through the annular groove 420. The entrance of the extension section 42 is designed as a trumpet shape with a smaller top and a larger bottom. The outer peripheral surface of the extension section 42 is provided with a retaining part 421. The side wall of the upper section of the retaining part 421 is vertical. The lower section of the retaining part 421 is a variable diameter section, and the circumferential profile dimension of the lower section gradually decreases from top to bottom. In this way, an annular groove 420 for retaining the circuit board 51 is formed between the upper section of the retaining part 421 and the elastic seal 40. The lower section of the retaining part 421 forms a conical surface with a larger top and a smaller bottom, which facilitates the operation of the extension section 42 passing through the circuit board 51.

[0054] Please see Figure 11 , Figure 12 The air regulating plate 21 has extension arms 211 on both sides in the width direction, and the symmetrically arranged extension arms 211 slide in cooperation with the slide groove 61. Specifically, the extension arms 211 have a hollow structure, so the extension arms 211 have a certain degree of elasticity. The thickness of the extension arms 211 is set to be less than the thickness of the air regulating plate 21, and the length of the extension arms 211 is set to be less than the length of the air regulating plate 21. The outer side wall of the extension arms 211 has an arc-shaped protrusion 212. The two sides of the slide groove 61 in the width direction have a series of continuous arc-shaped grooves 62. The arc-shaped grooves 62 match the arc-shaped protrusions 212. In this way, when the air regulating plate 21 is slid left and right, the arc-shaped protrusions 212 of the extension arms 211 slide from one arc-shaped groove 62 to another adjacent arc-shaped groove 62. The arrangement of the arc-shaped protrusions 212 and the arc-shaped grooves 62 can improve the feel of the air regulating operation.

[0055] See Figure 13 , Figure 14The elastic seal 40 has a mounting cavity 45 communicating with the air intake cavity 41, and the airflow sensing component 52 is fixed inside the mounting cavity 45. Specifically, the mounting cavity 45 is located near one corner of the elastic seal 40, and the elastic seal 40 has a stepped hole 46, which includes a small-diameter hole 460 and a large-diameter hole 461. The diameter of the large-diameter hole 461 is larger than that of the small-diameter hole 460, and the two are coaxially arranged. The large-diameter hole 461 is adapted to the airflow sensing component 52, and the hole wall of the large-diameter hole 461 forms the mounting cavity 45, which is used to seal the airflow sensing component 52. The second receiving cavity 430 can be connected to the sensing membrane of the airflow sensing component 52 through the small-diameter hole 460, so that the airflow sensing component 52 can sense changes in air pressure.
