Detailed Implementation

[0043] 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.

[0044] Please refer to Figure 1 and Figure 2 One embodiment of this application provides an atomizing device, comprising:

[0045] The housing assembly 10 includes a first housing 11, and the two ends of the first housing 11 are respectively provided with a mouthpiece 12 and an opening 13.

[0046] The battery holder 20 is disposed inside the housing assembly 10 and is sealed to the opening 13 of the first housing 11. The battery holder 20 and the inner wall of the first housing 11 together define a liquid storage chamber 30, which is used to store the aerosol matrix.

[0047] The atomizing component 40 is disposed between the mouthpiece 12 and the battery holder 20 and is connected to the liquid storage chamber 30. The atomizing component 40 is configured to heat and atomize the aerosol matrix to form an aerosol that is output from the mouthpiece 12.

[0048] In this embodiment, the housing assembly 10 is a housing structure for accommodating the battery holder 20 and the atomizing assembly 40 in the atomizing device. The housing assembly 10 includes a first housing 11, with a mouthpiece 12 and an opening 13 communicating at both ends. In this embodiment, the mouthpiece 12 and the first housing 11 are integrally formed, eliminating the need for separate production and assembly of the mouthpiece and housing, thus simplifying the installation process of the atomizing device. In this embodiment, the opening 13 and the mouthpiece 12 are connected, allowing airflow to be directed towards the mouthpiece 12 inside the atomizer.

[0049] In this embodiment, the battery holder 20 is disposed within the housing assembly 10 and is sealed to the opening 13 of the first housing 11. The battery holder 20 and the first housing 11 together define the liquid storage chamber 30. That is, in this embodiment, the traditional sealed design of the liquid storage chamber 30 is eliminated; there is no need to use silicone parts to define and seal the liquid storage chamber 30. Instead, the liquid storage chamber 30 is directly defined and sealed by the battery holder 20, thereby simplifying the internal structure of the atomizing device. This design minimizes the number of components in the atomizing device, reduces its cost, and improves its cost-effectiveness.

[0050] In this embodiment, the atomizing component 40 is used to heat and atomize the aerosol matrix in the liquid storage chamber 30 to form an aerosol. The aerosol is output from the mouthpiece 12 and can then be inhaled by the user.

[0051] Please continue to refer to this. Figure 2 and Figure 3 In one embodiment, the battery bracket 20 is provided with a locking part 21 at one end near the liquid storage chamber 30, and the first housing 11 is provided with a corresponding slot 111 at the opening 13. The battery bracket 20 is inserted into the slot 111 through the locking part 21 so that the battery bracket 20 is snapped into the first housing 11.

[0052] In this embodiment, the structure of the sealed connection between the battery bracket 20 and the first housing 11 is further optimized. By setting a locking part 21 at one end of the battery bracket 20 near the liquid storage chamber 30, and a corresponding locking groove 111 is set at the opening 13 of the first housing 11, the battery bracket 20 and the first housing 11 are sealed together by the snap-fit ​​connection between the locking part 21 and the locking groove 111, thereby ensuring the sealing effect of the battery bracket 20 on the liquid storage chamber 30.

[0053] Please continue to refer to this. Figure 2 and Figure 4 In one embodiment, the battery holder 20 is provided with a sealing part 22, which is inserted into the opening 13 of the first housing 11;

[0054] The peripheral side of the sealing part 22 is interference-fitted with the inner wall of the first housing 11;

[0055] Alternatively, a rib structure 221 may be provided on the periphery of the sealing part 22 near the liquid storage cavity 30, and a stepped structure 112 may be provided on the inner wall of the first housing 11. The stepped structure 112 and the rib structure 221 may be sealed together by ultrasonic welding.

[0056] In this embodiment, the sealing connection structure between the battery holder 20 and the first housing 11 is further optimized. Specifically, the sealing part 22 on the battery holder 20 is inserted into the opening 13 of the first housing 11, and the opening 13 is sealed by the sealing part 22.

[0057] Specifically, in one example, the sealing method between the sealing part 22 and the opening 13 of the first housing 11 is such that the periphery of the sealing part 22 and the inner wall of the first housing 11 are in an interference fit. That is, a portion of the periphery of the sealing part 22 protrudes to form an interference fit with the inner wall of the first housing 11 corresponding to the position of the opening 13, thereby achieving a seal.

[0058] In another example, the sealing method between the sealing part 22 and the opening 13 of the first housing 11 is to provide a rib structure 221 on the periphery of the sealing part 22 near the liquid storage chamber 30, and to provide a step structure 112 on the inner wall of the first housing 11. The step structure 112 and the rib structure 221 are sealed together by ultrasonic welding to achieve sealing.

[0059] To further explain the ultrasonic welding method, specifically, the rib structure 221 is placed on the step position of the step structure 112, and the first housing 11 and the battery bracket 20 are pressed together. Then, an ultrasonic welding machine is used to release ultrasonic waves to melt the protruding ribs, so that the battery bracket 20 and the first housing 11 are bonded together to form a whole, thereby completing the ultrasonic welding.

[0061] In this embodiment, the installation of the atomizing component 40 within the battery holder 20 is further optimized. The atomizing component 40 is fixed within the battery holder 20 and the first housing 11 by securing one end of the atomizing component 40 to the mouthpiece 12 and the other end to the mounting hole 23 of the battery holder 20.

[0062] Please refer to Figure 2 , Figure 5 and Figure 6 In one embodiment, the inner wall of the liquid storage cavity 30 near the nozzle portion 12 protrudes to form a step portion 31. The step portion 31 has a first side surface 311 near the nozzle portion 12 and a second side surface 312 away from the nozzle portion 12. The step portion 31 defines a first receiving space 32 of the liquid storage cavity 30 through the first side surface 311, and defines a second receiving space 33 of the liquid storage cavity 30 through the second side surface 312.

[0063] The atomizing device also includes a first liquid storage component 34 and a second liquid storage component 35 for storing the aerosol matrix. The first receiving space 32 is circumferentially fitted with the first liquid storage component 34 through a first side 311 to accommodate the installation of the first liquid storage component 34. The second receiving space 33 abuts against the end face of the second liquid storage component 35 through a second side to accommodate the installation of the second liquid storage component 35.

[0064] In this embodiment, a step portion 31 is added to the inner wall of the liquid storage chamber 30. The first side 311 near the nozzle portion 12 and the second side 312 away from the nozzle portion 12 define a first receiving space 32 for accommodating the first liquid storage component 34 and a second receiving space 33 for accommodating the second liquid storage component 35, respectively. Please refer to [reference needed] in this embodiment. Figure 2 The first receiving space 32 is defined on the inner side of the step portion 31 by the first side 311, and the second receiving space 33 is defined below the step portion 31 by the second side 312. The inner diameter of the first receiving space 32 is smaller than the inner diameter of the second receiving space 33, and the height of the second receiving space 33 is smaller than the height of the first receiving space 32.

[0065] In one example, please refer to Figure 5 The liquid storage chamber 30 is provided with a first liquid storage component 34. The circumferential sidewall of the first liquid storage component 34 is attached to the first side surface 311 of the step portion 31 and is installed in the first receiving space 32 defined by the first side surface 311.

[0066] In another example, please refer to Figure 5 A second liquid storage component 35 is provided in the liquid storage cavity 30. The top end face of the second liquid storage component 35 abuts against the second side surface 312 of the step portion 31 and is installed in the second receiving space 33 defined by the second side surface 312.

[0067] In one embodiment, the capacity of the first reservoir 34 and the second reservoir 35 is 2-4 ml. In another embodiment, the capacity of the first reservoir 34 is 2 ml and the capacity of the second reservoir 35 is 3 ml. In yet another embodiment, the capacity of the first reservoir 34 is 3 ml and the capacity of the second reservoir 35 is 2 ml.

[0068] In one embodiment, the height of the first liquid reservoir 34 is greater than the height of the second liquid reservoir 35 along the airflow direction within the atomizing device. During use, the required liquid reservoir can be replaced according to actual needs, and the stepped portion 31 can press down on and limit the position of the liquid reservoir.

[0069] Please refer to Figure 7 and Figure 8 In one embodiment, the battery bracket 20 further includes a first mounting groove 24 and a second mounting groove 25. The first mounting groove 24 is disposed on the side of the battery bracket 20 close to the liquid storage chamber 30, and the second mounting groove 25 is disposed on the side of the battery bracket 20 away from the liquid storage chamber 30.

[0070] The atomizing device also includes a battery cell 50 and an airflow sensor 60.

The battery cell 50 is electrically connected to the airflow sensor 60 and the atomizing assembly 40, respectively. The atomizing assembly 40 is electrically connected to the airflow sensor 60.

[0071] In this embodiment, the structure of the battery bracket 20 is further optimized. The battery bracket 20 also includes a first mounting groove 24 and a second mounting groove 25. The first mounting groove 24 is used to accommodate the battery cell 50, and the second mounting groove 25 is used to accommodate the airflow sensor 60.

[0072] In this embodiment, the airflow sensor 60 senses the airflow within the atomizing device, thereby controlling the operation of the atomizing assembly 40. In this embodiment, the battery cell 50 provides power to the atomizing assembly 40 and the airflow sensor 60.

[0073] In one embodiment, the airflow sensor 60 is a microphone.

[0074] Please refer to Figure 2 and Figure 9 In one embodiment, the battery holder 20 further includes an air intake channel 114 and a first detection hole 113, and the housing assembly 10 has an air intake hole 26 and a second detection hole 27.

[0076] In this embodiment, the structure of the battery holder 20 and the housing assembly 10 is further optimized. By providing an air intake channel 114 in the battery holder 20 and an air intake hole 26 in the housing assembly 10, airflow from outside the atomizing device can enter the atomizing device and then into the atomizing component 40 to help form an aerosol. By providing a first detection hole 113 in the battery holder 20 and a second detection hole 27 in the housing assembly 10, gas from outside the atomizing device can enter the airflow sensor 60 through the second detection hole 27 when the user inhales, and be detected by the airflow sensor 60, thereby controlling the activation of the atomizing component 40 in the atomizing device. That is, in this embodiment, the airflow channel for aerosol generation and the airflow channel for sensing the inhalation action are provided separately.

[0077] Please refer to Figure 2 and Figure 10 In one embodiment, the atomizing component 40 includes:

[0081] In this embodiment, the structure of the atomizing component 40 is further optimized. The outer tube 41 is used to install the atomizing core 42. At the same time, the atomizing core 42 is connected to the aerosol matrix liquid path in the liquid storage chamber 30 through the notch 411 provided on the outer tube 41.

[0083] In this embodiment, a fiberglass inner tube 43 is provided inside the outer tube 41. The fiberglass inner tube 43 can restrict the axial movement of the atomizing core 42, thereby positioning the atomizing core 42 within the outer tube 41. Simultaneously, since the notch 411 may affect the flow direction of the aerosol, the fiberglass inner tube 43 is at least partially blocked by the notch 411 to facilitate the flow of the aerosol towards the nozzle portion 12.

[0085] In this embodiment, the battery bracket 20 is mounted on the second housing 14, and the mounting connection between the first housing 11 and the second housing 14 is further optimized. Specifically, the first housing 11 and the second housing 14 are installed by plugging in the second mating part 115 on the first housing 11 and the first mating part 141 on the second housing 14.
