[0002] An atomizer is the part of an atomizing device used to atomize an internal aerogel matrix to produce aerogel. It requires an internal sensor to detect airflow and activate, and therefore, the sensor is typically located within the airflow channel inside the atomizer. In actual production processes, atomizers need to undergo backflush testing to verify their quality.

[0003] However, during the backflush test, it is easy to blow aerosol onto the sensor, causing it to adhere and accumulate on the sensor, affecting the sensitivity and lifespan of the sensor in subsequent use, or even causing the sensor to fail, thus affecting the quality of the atomizer.

Detailed Implementation

[0034] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0035] Please refer to Figure 1 , Figure 2 and Figure 3 One embodiment of this application provides a sensing device 100 for powering an atomizer 200, comprising:

[0036] Circuit board 10;

[0037] The sensor 20 is disposed on the surface of the circuit board 10 and is used to sense the suction action;

[0038] The first sealing element 30 is disposed on the side of the sensing element 20 away from the circuit board 10, and is used to at least partially cover the sensing element 20.

[0039] The surface of the first sealing member 30 away from the sensing member 20 is provided with a drainage groove 31, and the drainage groove 31 is provided with a protruding structure 311, making the drainage groove 31 a non-linear groove.

[0040] The flow channel 31 is used to transmit changes in airflow within the atomizer 200, enabling the sensor 20 to detect these changes. In other words, the independently designed flow channel 31, serving as a sensing channel, allows the sensor 20 to operate normally without needing to be located within the airflow channel of the atomizer 200.

[0041] The sensor 20 is used to detect or sense the airflow in the atomizer 200, that is, the pressure change in the flow channel 31, and thus sense the airflow in the airflow channel of the atomizer 200. Therefore, it can sense the user's inhalation action.

[0042] The protruding structure 311 on the flow channel 31 can transform the flow channel 31 into a non-linear channel, thereby extending the length of the flow channel 31. This extends the path of aerosol flow in the airflow channel of the atomizer to the sensor 20, thereby reducing the probability of aerosol flowing to the sensor 20, improving the sensitivity and service life of the sensor 20, and thus improving the user experience.

[0043] In one example, the drainage channel 31 is a curved channel, such as a wavy channel, an arc-shaped channel, or a spiral channel, and its protruding structure 311 is provided at the corresponding curved position. In another example, the drainage channel 31 is a bent channel, in which case the protruding structure 311 is provided at the corresponding bend or corner position, making the channel a multi-segment broken line shape. That is, this application does not limit the specific shape of the protruding structure 311.

[0044] In one embodiment, please refer to Figure 2 and Figure 3 It also includes:

[0045] The second seal 40 and the first seal 30 together form the connecting cavity 50 of the atomizing chamber 400 of the atomizer 200, and the connecting cavity 50 is connected to one end of the drainage groove 31.

[0046] The first sealing element 30 is also provided with an installation groove 31, which is connected to the end of the drainage groove 31 away from the connecting cavity 50, and the sensing element 20 is disposed in the installation groove 31.

[0047] The second seal 40 is used to cooperate with the first seal 30 to form a communicating cavity 50.

[0048] The connecting cavity 50 is connected to the atomizing cavity 400 of the atomizer 200 to help the atomizing core assembly 80 form an aerosol in the airflow channel when heated. The connecting cavity 50 is connected to the guide groove 31 so that the pressure change inside the connecting cavity 50 caused by the airflow in the atomizing cavity 400 can be transmitted to the sensor 20 through the guide groove 31 and detected by the sensor 20.

[0049] The mounting slot 31 is used to mount the sensor 20 and to protect the sensor 20.

[0050] For details, please refer to Figure 1 , Figure 2 and Figure 3The second sealing element 40 is described below. The second sealing element 40 may have a groove, allowing it to cooperate with the first sealing element 30 to form a communicating cavity 50. The second sealing element 40 has a through hole 41. The atomizer 200 also includes an atomizing airway 60, a liquid storage chamber 70, and an atomizing core assembly 80. The atomizing core assembly 80 is disposed within the atomizing airway 60, and an atomizing cavity 400 is formed within it. The atomizing cavity 400 communicates with both the liquid storage chamber 70 and the atomizing airway 60. Simultaneously, the atomizing cavity 400 communicates with the communicating cavity 50 through the through hole 41. When the atomizing core assembly 80 is activated, it heats the aerosol matrix within the liquid storage chamber 70, causing it to form an aerosol within the atomizing cavity 400. The aerosol flows with the airflow through the atomizing airway 60 and reaches the mouthpiece 90 of the atomizer 200 for inhalation. The second sealing element 40 serves as a partial sealing structure for the liquid storage chamber 70.

[0051] Please refer to Figure 2 and Figure 3 The connecting cavity 50 is described below. The connecting cavity 50 is also equipped with absorbent cotton 51 to seal the connecting cavity 50 and prevent leakage.

[0052] Please refer to Figure 2 and Figure 3 The connection between the connecting cavity 50 and the atomizing cavity 400 is also provided with a condensation absorbent cotton 52 to prevent the condensate generated when the atomizing core assembly 80 is heated to form an aerogel from flowing into the connecting cavity 50.

[0053] Please refer to Figure 2 and Figure 3 The first sealing element 30 is described below. The first sealing element 30 may also have a groove, which can cooperate with the second sealing element 40 to form a communicating cavity 50. Alternatively, the second sealing element 40 and the first sealing element 30 may each have a groove to cooperate to form a communicating cavity 50.

[0054] Please continue to refer to this. Figure 2 and Figure 3 The second seal 40 and the first seal 30 cooperate to form a drainage groove 31. This can be achieved by either having a groove on the second seal 40 to mate with the first seal 30, or by having a groove on the first seal 30. The mounting groove 31 can be located not only on the first seal 30, but also on the second seal 40, or between the second seal 40 and the first seal 30, as long as it communicates with the drainage groove 31. The first seal 30 can also be used to mount a circuit board.

[0055] In one embodiment, please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6The drainage channel 31 is provided with multiple protruding structures 311, which are spaced apart on the channel wall of the drainage channel 31.

[0056] Among them, at least two protruding structures 311 are relatively staggered and arranged on the groove wall.

[0057] In this embodiment, the drainage groove 31 is disposed on the side of the first seal 30 facing the second seal 40, and the protruding structure 311 is disposed in the drainage groove 31, thereby forming a non-linear drainage groove 31.

[0058] For details, please refer to Figure 5 and Figure 6 At least two protruding structures 311 are disposed opposite to each other on the channel wall. The protruding structures 311 disposed opposite to each other on both sides can be staggered and asymmetrically arranged so that the channel is a non-linear channel. In one embodiment, the protruding structures 311 disposed opposite to each other on both sides can also be symmetrically arranged so that the cross-sectional area of ​​the channel at the corresponding position can be reduced by the symmetrically arranged protruding structures 311, thereby hindering the flow of aerosols.

[0059] In one embodiment, please refer to Figure 2 , Figure 3 , Figure 5 and Figure 6 A transition channel 43 is also provided between the second seal 40 and the first seal 30. The connecting cavity 50 is connected to the drainage groove 31 through the transition channel 43, and there is an angle between the transition channel 43 and the drainage groove 31.

[0060] In this embodiment, the structure between the second seal 40 and the first seal 30 is further optimized. The transition channel 43 is formed by the second seal 40 and the first seal 30, and is set at an angle to the drainage groove 31. At this time, the aerosol in the connecting cavity 50 first enters the transition channel 43. Due to the angle between the transition channel 43 and the drainage groove 31, the aerosol enters the drainage groove 31, which is blocked or delayed. Finally, the protruding structure 311 in the drainage groove 31 further blocks or delays the aerosol.

[0061] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 4 The sensing device 100 also includes:

[0062] The blocking member 42 is disposed at the connection between the connecting cavity 50 and the drainage groove 31. The end of the blocking member 42 near the drainage groove 31 is connected to the second seal 40, and the end of the blocking member 42 away from the drainage groove 31 is spaced apart from the first seal 30 to form a transition channel 43.

[0063] In this embodiment, the blocking member 42 is used to further prevent aerosol from entering the drainage channel 31. One end of the blocking member 42 is connected to the second sealing member 40 to seal the connection, while the other end is spaced apart from the first sealing member 30, thus creating a spaced channel between them to ensure communication between the connecting cavity 50 and the drainage channel 31, ensuring that the sensing element 20 can sense the negative pressure change. Simultaneously, the blocking member 42 is spaced apart from the first sealing member 30, rather than from the second sealing member 40, further preventing aerosol in the connecting cavity 50 from entering the drainage channel 31. Therefore, the aerosol in the connecting cavity 50 is first blocked by the blocking member 42, preventing or delaying its entry into the transition channel 43, further ensuring that the sensing element 20 is not adhered to by aerosol.

[0064] In one example, the barrier 42 is a baffle. In another example, the barrier 42 is integrally formed with the second seal 40, making it easy to assemble. At the same time, the design of the barrier 42 can block most of the aerosol without adding extra cost.

[0065] In this embodiment, please refer to Figure 2 , Figure 3 and Figure 4 The blocking member 42 can be arranged perpendicular to the second seal 40, and the transition channel 43 can also be arranged perpendicular to the drainage groove 31. In this embodiment, the blocking member 42 can be arranged to cooperate with the corresponding mounting groove 31 in the first seal 30 to form the transition channel 43.

[0066] In one embodiment, please refer to Figure 2 and Figure 3 The first sealing element 30 is also provided with an air inlet 32, which is connected to the connecting cavity 50. The blocking element 42 is provided on the side adjacent to the air inlet 32.

[0067] In this embodiment, the air inlet 32 ​​is the air inlet end of the connecting cavity 50. The blocking member 42 is positioned adjacent to the air inlet 32, so that when the aerosol entering the connecting cavity 50 is blocked by the blocking member 42, it is cooled and condensed into droplets at the air inlet 32, and then discharged from the air inlet 32 ​​without entering the transition channel 43. Therefore, this setting can increase the difficulty for aerosol to enter the drainage groove 31.

[0068] In one embodiment, please refer to Figure 2 , Figure 3 and Figure 5 The mounting groove 31 is located on the side of the first seal 30 away from the drainage groove 31. The mounting groove 31 is provided with a connecting hole 312, and the mounting groove 31 is connected to the drainage groove 31 through the connecting hole 312.

[0069] And / or, the sensing element 20 is an airflow sensor.

[0070] In this embodiment, the setting position and structure of the mounting groove 31 are optimized so that the first sealing member 30 protrudes towards the direction of the drainage groove 31 at the position corresponding to the mounting groove 31, thereby helping the blocking member 42 and the first sealing member 30 to form a transition channel 43 that can be set at an angle with the drainage groove 31.

[0071] In another embodiment, the sensor 20 is a microphone. Please refer to [reference needed]. Figure 2 and Figure 3 A protective element 201 is provided between the sensing element 20 and the mounting groove 31 to protect the sensing element 20 from interference by aerosol.

[0072] The atomizer provided according to the above embodiments features a flexible design for its flow channel 31, a simple and stable structure, and easy assembly without increasing assembly difficulty. This enhances structural stability and makes the design and manufacturing processes more stable. Furthermore, it maintains a consistent flavor during actual use, improving the atomizer's quality and enhancing its performance in actual testing without increasing costs. It also eliminates liquid spillage during use.

[0073] Please refer to Figure 1 and Figure 6 Another embodiment of this application provides an atomizing device 1000, which includes any of the above-mentioned sensing devices 100. The atomizing device 1000 also includes an atomizer 200, which is connected to the sensing device 100. The sensing device 100 is used to supply power to the atomizer 200.

[0074] Among them, sensing device 100

[0075] The atomizing device also includes a battery assembly 300, which can be installed within the atomizing device 1000.

[0076] The battery assembly 300 includes a battery 301, a display panel 302, and a circuit board 10. The battery 301 is located on the side of the second seal 40 away from the flow channel 31, and absorbent cotton 303 is placed between the battery 301 and the second seal 40. The display panel 302 is located on one side of the battery 301 and connected to the circuit board 10. The display panel 302 is used to control the operating mode of the atomizer 200. The circuit board 10 is located on the side of the first seal 30 away from the flow channel 31, and the sensor 20 is located on the side of the circuit board 10 closer to the first seal 30. The side of the circuit board 10 away from the first seal 30 also has a button 304 and a charging interface 305. The button 304 is used to increase the power of the atomizer, and the charging interface 305 is used for charging.

[0077] In one embodiment, the display panel 302 is provided with a mask and a plurality of LED beads, which are correspondingly disposed in the openings of the mask to avoid optical crosstalk between adjacent beads. The plurality of LED beads can be used to display the battery level of the battery 301, the sensing status of the sensor 20, and the remaining liquid level in the liquid storage chamber 70. For example, different conditions can be displayed by the color and emission frequency of the LED beads; the specific design can be tailored to actual needs and will not be elaborated further here.

[0078] In one embodiment, a condensation return cotton 306 is provided between the liquid storage chamber 70 and the suction nozzle 90 to improve the sealing between the liquid storage chamber 70 and the suction nozzle 90 to avoid leakage.

[0079] In one example, circuit board 10 is a charging board.

[0080] In one example, charging port 305 is a Type-C charging port.

[0081] In one embodiment, please refer to Figure 2 and Figure 3 An air intake channel 202 is also formed inside the atomizer 200. One end of the air intake channel 202 is connected to the connecting cavity 50, and the other end of the air intake channel 202 is connected to the outside of the atomizer 200.

[0082] In this embodiment, the air intake channel 202 is used to allow external gas to enter the communicating cavity 50 through the air intake channel 202 to form an aerosol.

[0083] In one embodiment, please refer to Figure 2 and Figure 3 The connection between the air intake channel 202 and the connecting cavity 50 is located near the connection between the connecting cavity 50 and the flow channel 31 of the sensing device 100.

[0084] In this embodiment, the connection point between the air intake channel 202 and the connecting cavity 50 is the air intake end of the connecting cavity 50. That is, the air intake end in the connecting cavity 50 is located near the connection point of the drainage groove 31, thereby helping the sensing element 20 to sense negative pressure changes more quickly. It is understood that the connection point between the air intake channel 202 and the connecting cavity 50 in this application can also be located at the connection point between the non-connecting cavity 50 and the drainage groove 31 of the sensing device 100.
