Description

Technical Field

[0001] This application relates to the field of atomization technology, specifically to an atomization device. Background Technology

[0002] The nebulizer atomizes an aerosol matrix into an aerosol for the user to inhale. The nebulizer has an atomizing chamber, a mouthpiece with an airflow channel connected to the atomizing chamber, and an air intake channel connecting the atomizing chamber and the atmosphere. When the user inhales, an airflow sequentially passes through the air intake channel, the atomizing chamber, and the airflow channel, carrying the aerosol generated by the nebulizer for the user to inhale.

[0003] For handheld atomizers, users hold the atomizer in their hands to use it. Since the space for human hands to hold the device is relatively limited, the size of such atomizers should not be too large in order to ensure a good grip experience. Utility Model Content

The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).

[0032] This application provides an atomizing device; please refer to [reference needed]. Figure 1 and Figure 2 The atomizing device includes a housing 10, an atomizer 20 and a battery unit 30 disposed within the housing 10, a mouthpiece 40 at the upper end of the housing 10, and a circuit board 50 (PCBA) on the inner side of the lower end of the housing 10. The battery unit 30 is mounted inside the housing 10 via a bracket 60. An FPC (Flexible Printed Circuit) screen 70 is also disposed inside the housing 10, and silicone 80 and a composite board 90 are disposed on the outer side of the housing 10.

[0033] Please refer to Figure 1 and Figure 2 The outer casing 10 includes an upper casing 11 and a bottom cover 12. The bottom cover 12 seals the opening at the lower end of the upper casing 11, thus the bottom cover 12 and the upper casing 11 form an inner cavity for mounting the corresponding components. Please refer to [reference needed]. Figure 3An air inlet 121 is provided on the bottom wall of the bottom cover 12, through which outside air can enter the outer casing 10. In order to control the airflow, an air regulating plate 122 is provided on the inside of the bottom cover 12. By changing the position of the air regulating plate 122, the amount of obstruction of the air inlet 121 by the air regulating plate 122 can be changed, thereby changing the actual flow capacity of the air inlet 121.

[0034] Please refer to Figure 1 and Figure 2 The atomizer 20 includes a mounting shell 21 and an aerosol matrix carrier 22 disposed within the mounting shell 21. The aerosol matrix carrier 22 carries an aerosol matrix that can be atomized into an aerosol. By disposing of the aerosol matrix carrier 22 within the mounting shell 21, the aerosol matrix is ​​stored within the mounting shell 21. In some embodiments, the aerosol matrix carrier 22 can be an oil storage cotton, the mounting shell 21 can be an oil cup, and the corresponding aerosol matrix can be oil.

[0035] The atomizer 20 has an atomizing chamber 23 located in the middle. The atomizing chamber 23 is a channel that runs vertically through the atomizing chamber to allow gas to pass through. An atomizing core 24 is provided inside the atomizing chamber 23. When the atomizing core 24 is powered on, it can atomize the aerosol matrix into an aerosol.

[0036] It should be noted here that, Figure 1 The structure and components of the atomizing device are displayed. Figure 2 No installation shell 21 is displayed.

[0037] The bracket 60 is disposed inside the housing 10 and located below the atomizer 20. The structure of the bracket 60 is as follows: Figure 4 As shown, it has a top wall 61, a back side wall 62, a left side wall 63, and a right side wall 64. The top wall 61, back side wall 62, left side wall 63, and right side wall 64 form a mounting space 65 for mounting the battery unit 30, and the battery unit 30 is mounted in the housing 10 by being mounted in the mounting space 65.

[0038] In some embodiments, a protruding structure 621 is provided on the back sidewall 62. The protruding structure 621 has a mounting groove 622 adapted to the shape of the battery unit 30. The battery unit 30 is installed in the mounting groove 622 to fix the position of the battery unit 30. The fixing of the position of the battery unit 30 mentioned here refers to fixing the position of the battery unit 30 in a corresponding direction based on the structure of the mounting groove 622.

[0039] When the protrusion 621 is a strip-shaped protrusion extending vertically, the mounting groove 622 engages with the outer peripheral surface of the battery unit 30, fixing the position of the battery unit 30 in the vertical direction. In other embodiments, the mounting groove 622 can also engage with the peripheral surface and the left and right end faces of the battery unit 30, thus fixing the position of the battery unit 30 in both the vertical and horizontal directions. The battery unit 30 can be a cylindrical battery, and the fitting mounting groove 622 is an arc-shaped groove. In some other embodiments, the protrusion 621 can also be provided on the left side wall 63 and / or the right side wall 64.

[0040] Please refer to Figure 4 The bracket 60 has an open structure on the side opposite to the back sidewall 62, which allows the battery unit 30 to be installed into the installation space 65 through the open structure.

[0041] The top wall 61 of the support 60 has a through hole 611 that penetrates the top wall 61 and communicates with the atomizing chamber 23. This communication is intended to indicate that airflow can flow from the space of the through hole 611 to the space of the atomizing chamber 23; the two spaces can be directly connected or indirectly connected. Other descriptions of airflow communication in this application also follow this pattern, allowing for both direct and indirect connections.

[0042] The through-hole 611 serves as the first channel for gas flow to the atomizing chamber 23. After the battery unit 30 is installed in the mounting space 65, there is a gap between the battery unit 30 and the bracket 60. This gap at least partially serves as a second channel for gas flow. Please refer to [reference needed]. Figure 4 The side of the bracket 60 opposite to the top wall 61 is also an open structure. In addition, there are openings on the back side wall 62 and the right side wall 64 of the bracket 60. That is, the bracket 60 as a whole is an open and non-closed structure. It can be understood that the second channel is an open channel, that is, the gap between the battery unit 30 and the bracket 60 is used as a channel for airflow.

[0043] Through hole 611 communicates with mounting space 65, and naturally, first channel and second channel are connected, as shown below. Figure 1 As shown by the middle arrow, the connected first and second channels form an air intake channel, allowing gas to flow into the atomizing chamber 23 through the air intake channel.

[0044] Please refer to Figure 1 and Figure 4 The installation space 65 is connected to the inner cavity of the outer shell 10, which in turn makes the second channel connected to the air inlet 121 on the bottom cover 12. The gas entering the outer shell 10 through the air inlet 121 can enter the second channel, flow through the air inlet channel to the atomizing chamber 23, and be inhaled by the user along with the aerosol generated in the atomizing chamber 23.

[0045] In this way, the air intake channel is formed by the through hole 611 provided on the top wall 61 of the bracket 60 and the gap between the battery unit 30 and the bracket 60. There is no need to set up a special component to set up the air intake channel. Compared with the atomizing device that sets up a special component to form the air intake channel, the atomizing device of this application can achieve a smaller size.

[0046] Since the second channel is open, a more concentrated airflow ensures greater stability of the airflow during absorption. In some embodiments, such as... Figure 5 As shown, the circuit board 50 is placed at the end of the bracket 60 opposite to the top wall 61, that is, the circuit board 50 is placed between the mounting space 65 and the air inlet 121. Furthermore, an air inlet channel is provided on the circuit board 50 for gas to pass through. In this way, the gas entering the housing 10 through the air inlet 121 can flow to the atomizing chamber 23 through the air inlet channel, the area in the mounting space 65 near the air inlet channel and the through hole 611, and the first channel (i.e., the through hole 611), forming the main airflow channel, so that the airflow is stable and controllable.

[0047] For the structure of the air intake duct on circuit board 50, please refer to [reference needed]. Figure 6 In some embodiments, the plate air inlet is a notch 51 on the circuit board 50. The first channel cooperates with the plate air inlet to form a mainstream airway within the open bracket 60, thereby improving the stability of the airflow during the suction process.

[0048] In one embodiment, the through hole 611 (i.e., the first channel) is aligned with the board air intake, wherein alignment means that at least a portion of the projection of the outline of the through hole 611 onto the circuit board 50 coincides with at least a portion of the outline of the board air intake.

[0049] Furthermore, the through-hole 611 is offset to the right and back on the top wall 61, and the plate air inlet, i.e., the notch 51, is located on the right side of the circuit board 50, on the side of the circuit board 50 facing the back wall 62 of the bracket 60. This allows it to cooperate with the right side wall 64, and under the enclosure of the right side wall 64, the airflow in the second channel is concentrated as much as possible through the area close to the right side wall 64. In addition, the air inlet 121 is also located on the right side of the bottom shell 12, making it easier for the gas entering the outer shell 10 through the air inlet 121 to enter the second channel through the plate air inlet.

[0050] By forming an air inlet channel with a notch 51 on the circuit board 50, the area occupied by the air inlet channel on the circuit board 50 can be minimized. After the circuit board 50 is mounted on the bracket 60, the circumferential opening of the notch 51 is blocked by the bracket 60, ensuring that the gas has a definite flow direction when passing through the air inlet channel. In some other embodiments, the air inlet channel may also include both the notch 51 and other holes formed on the circuit board 50. Of course, the air inlet channel may also simply be a hole formed on the circuit board 50.

[0051] Regarding the mounting method of the circuit board 50 within the housing 10, in some embodiments, slots 66 are provided at the ends of the back sidewall 62, left sidewall 63, and right sidewall 64 of the bracket 60 away from the top wall 61, and the circuit board 50 is inserted into the bracket 60 through the slots 66. To prevent the circuit board 50 from slipping out along the slots 66, a snap-fit ​​structure is also provided between the circuit board 50 and the bracket 60 to lock the circuit board 50 onto the bracket 60.

[0052] In some embodiments, please refer to Figure 4 , Figure 5 and Figure 6 The snap-fit ​​structure includes an elastic hook 67 located on the bracket 60 and a snap hole 52 located on the circuit board 50. After the circuit board 50 is installed in place on the bracket 60, the hook of the elastic hook 67 engages with the snap hole 52. In other embodiments, the snap-fit ​​structure may also include protrusions provided on the groove wall of the slot 66 and grooves located on the circuit board 50. The circuit board 50 is fixed to the bracket 60 by the engagement of the protrusions in the grooves.

[0053] In some other embodiments, a mounting structure for mounting the circuit board 50 can be provided inside the bottom cover 12. Specifically, a protrusion can be provided inside the bottom cover 12, with a threaded hole at the center of the protrusion. A matching mounting hole can be provided on the circuit board 50. The circuit board 50 can be mounted on the bottom cover 12 by inserting a screw into the mounting hole and screwing it into the threaded hole. This also realizes the installation of the circuit board 50 between the mounting space 65 and the air inlet 121.

[0054] An air inlet 121 is located on the bottom cover 12 of the outer casing 10. No air inlet 121 is located on the circumferential sidewall of the outer casing 10. However, during actual assembly, there is generally a gap between the bracket 60 and the circumferential sidewall of the outer casing 10, and this gap communicates with the air inlet 121. Therefore, by providing a bracket air inlet channel on the wall of the bracket 60 corresponding to the circumferential sidewall of the outer casing 10, an additional path for gas to enter the second channel can be formed, in addition to the existing path for gas to enter the second channel via the plate air inlet channel. This increases the amount of gas entering the second channel, ensuring sufficient gas volume during inhalation. Here, "corresponding" refers to the portion of the bracket 60 whose outer wall surface faces the circumferential sidewall of the outer casing 10.

[0055] In one embodiment, the back sidewall 62 is a portion of the wall corresponding to the circumferential sidewall of the bracket 60 and the outer casing 10. The air intake of the bracket is an elongated hole 623 provided on the back sidewall 62. The elongated hole 623 is a hole that penetrates the wall thickness of the back sidewall 62. The first channel, i.e., the through hole 611, and the air inlet 121 are arranged vertically at intervals. The length of the elongated hole 623 extends in the vertical direction, so that the airflow can flow along the length of the elongated hole 623 to the first channel. Figure 4As indicated by the middle arrow, the elongated hole 623 is located at the right end of the back sidewall 62, near the plate air inlet, i.e., the notch 51, allowing gas to flow more concentratedly through the second channel. In other embodiments, the lower end of the bracket 60 has a sidewall. In this case, the opening of the bracket air inlet can also be partially on the sidewall at the lower end of the bracket 60, making the air inlet size of the bracket air inlet larger, so as to have a larger air intake volume.

[0056] In other embodiments, the air inlet 121 may be disposed on the circumferential sidewall of the housing 10, and the bracket 60 may have a wall corresponding to the bottom cover 12. In this case, a bracket air inlet may be disposed on the wall of the bracket 60 opposite to the bottom cover 12.

[0057] Alternatively, the circuit board 50 may not have an air inlet. Instead, the gas entering the housing 10 through the air inlet 121 enters the bracket 60 through the bracket air inlet. In this case, the installation position of the circuit board 50 can be selected according to the internal structural layout of the atomizing device.

[0058] Since the second channel is an open structure, in order to promote the flow of gas into the first channel, i.e., the through hole 611, a rib 612 is provided around the opening of the through hole 611 that connects to the installation space 65. The rib 612 constrains the gas flow into the through hole 611, i.e., the first channel.

[0059] Battery cell 30 and atomizer core 24 are electrically connected via wire 241. Please refer to [reference needed]. Figure 1 and Figure 4 The top wall 61 of the bracket 60 is also provided with a wire passage hole 613. The wire passage hole 613 and the through hole 611 are two relatively independent holes. The wire 241 passes through the wire passage hole 613 and connects between the battery unit 30 and the atomizing core 24. A sealing structure is provided between the wire passage hole 613 and the wire 241. The sealing structure can be a cured sealant, a silicone sealing block, a rubber sealing block, etc.

[0060] The circuit board 50 is used to implement control functions, such as controlling the on / off supply of power from the battery unit 30 to the atomizing core 24. The circuit board 50 needs to be controlled according to corresponding signals; therefore, a pneumatic switch 110 is installed between the atomizer 20 and the mouthpiece 40 via a first seal 100. The pneumatic switch 110 can transmit signals to the circuit board 50 based on sensed changes in air pressure. A first liquid-absorbing element 120 is also provided between the first seal 100 and the atomizer 20 for absorbing the generated liquid.

[0061] To absorb the liquid entering the support 60, the atomizing device also includes a second liquid-absorbing element 130 and a third liquid-absorbing element 140 disposed within the support 60 and respectively located on the upper and lower sides of the battery unit 30. For example... Figure 1 and Figure 2As shown, a second sealing element 150 is provided between the bracket 60 and the mounting shell 21 to achieve a sealed connection between the bracket 60 and the mounting shell 21. In some embodiments, the bracket 60 and the mounting shell 21 are connected by a snap-fit ​​connection. The second sealing element 150 has an inner cavity, in which a fourth liquid-absorbing element 160 is provided. The first channel is indirectly connected to the atomizing chamber 23 through the inner cavity of the second sealing element 150. The fourth liquid-absorbing element 160 can absorb the liquid entering the inner cavity of the second sealing element 150. In addition, a fifth liquid-absorbing element 170 is also provided in the sensing air path of the pneumatic switch 110 to absorb the liquid.

[0062] The above examples illustrate this application only to aid understanding and are not intended to limit its scope. Those skilled in the art to which this application pertains can make various simple deductions, modifications, or substitutions based on the ideas presented.
