Abstract
Description
Technical Field
[0001] This application relates to the field of atomization technology, specifically to an atomization device. Background Technology
[0002] The atomizing device atomizes the atomizing matrix into an aerosol through an atomizer for the user to inhale. In actual use, the user inhales intermittently. Therefore, the atomizer is required to respond to the user's inhalation action and atomize the atomizing matrix, that is, to atomize only during inhalation.
[0003] To achieve the above objectives, one feasible approach is to install a sensor within the atomizing device. This sensor detects the pressure changes caused by the user's inhalation and sends a signal to the controller. The controller then controls the atomizer's operation based on the received signal. To ensure a good user experience, the sensor needs to be highly sensitive to quickly detect the inhalation action, while also preventing the sensor from automatically activating and causing the atomizer to start falsely. Utility Model Content
[0004] This application provides an atomizing device that improves the response speed of the sensing element while reducing the probability of the atomizer being falsely activated.
[0005] One embodiment of this application provides an atomizing device, comprising: a nozzle having an airflow channel for aerosol passage, the nozzle also having a cavity isolated from the airflow channel, the cavity having an opening; a sealing structure having a sealing fit with the nozzle and sealing the opening to enclose the cavity into a sensing chamber, the sealing structure having a mounting cavity and a sensing air passage, both the mounting cavity and the sensing air passage communicating with the sensing chamber, the sensing air passage and the airflow channel communicating outside the sensing chamber, such that a suction action acting on the airflow channel causes at least a change in the air pressure of the sensing chamber; and a sensing element mounted in the mounting cavity for sensing the change in air pressure within the sensing chamber to generate an electrical signal.
[0006] In one embodiment, at least one of the sensing airways is a branched airway, the branched airway including a channel connecting section communicating with the airflow channel and a chamber connecting section communicating with the sensing chamber, the channel connecting section being provided with at least two, and / or the chamber connecting section being provided with at least two; and / or the sealing structure is provided with at least two non-communicating sensing airways.
[0007] In one embodiment, the sealing structure has a groove on the side facing away from the sensing chamber, the airflow channel communicates with the groove, the sealing structure also has a communicating channel connecting the sensing chamber and the groove, the groove and the communicating channel constitute a sensing airway, and the atomizing device further includes a first liquid-absorbing element, which covers or blocks the opening of the groove.
[0008] In one embodiment, the sealing structure has a communication hole communicating with the airflow channel, the groove includes a winding groove segment circumferentially surrounding the communication hole, the groove wall of the winding groove segment has a first communication port communicating with the communication hole, and at least two first communication ports are spaced apart circumferentially along the communication hole.
[0009] In one embodiment, the groove wall of the winding groove section is provided with a second communication port that communicates with the communication channel, and the first communication port and the second communication port are staggered along the circumference of the communication hole.
[0010] In one embodiment, the groove further includes a connecting groove segment between the connecting channel and the winding groove segment. There are at least two connecting channels, each of which is connected to the winding groove segment through a corresponding connecting groove segment. The sealing structure has a groove on the side facing away from the sensing chamber, the groove connecting two adjacent connecting channels, and the depth of the groove is less than the depth of the groove.
[0011] In one embodiment, the mounting cavity has a connecting port that communicates with the sensing chamber, the sensing airway has an airway connecting port that communicates with the sensing chamber, and a second liquid suction element is installed between the connecting port and the airway connecting port via a mounting groove. The mounting groove has a passageway on its wall near the airway connecting port for airflow to pass through.
[0012] In one embodiment, at least one end of the groove wall of the passage is bent toward the location of the airway connection port.
[0013] In one embodiment, the sealing structure is a split structure, including a first part and a second part. The sealing structure is sealed with the nozzle through the first part. The mounting cavity is a through hole that passes through the first part. The second part and the first part cooperate to form an atmospheric channel. One end of the atmospheric channel is connected to the mounting cavity, and the other end has an atmospheric connection port located on the outer surface of the sealing structure.
[0014] In one embodiment, the nozzle includes an inner tube and an outer shell, the inner cavity of the inner tube forms the airflow channel, the outer shell is connected to the inner tube, and the outer shell and the inner tube form an annular cavity.
[0015] According to the atomizing device in the above embodiments, the sealing structure and the mouthpiece are sealed together to enclose the cavity on the mouthpiece into a sensing chamber. A sensing element is installed in the mounting cavity on the sealing structure. The sensing element can sense the change in air pressure inside the sensing chamber. The sensing chamber is connected to the airflow channel through the sensing airway. When the user inhales through the mouthpiece, the inhalation action creates airflow in the airflow channel, which in turn creates negative pressure in the sensing chamber through the sensing airway. The sensing element senses the change in air pressure inside the sensing chamber and generates an electrical signal, thus activating the atomizer. Since the sensing airway is located on the sealing structure that cooperates with the mouthpiece, it is close to the mouthpiece, allowing the sensing element to be activated as soon as the user inhales. The sensing airway is also indirectly connected to the mounting cavity through the sensing chamber. In the event of a false triggering factor, the sensing chamber can buffer the situation, reducing the probability of the sensing element activating on its own, thereby reducing the probability of the atomizer activating falsely.

[0031] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments, and the operational steps involved in each embodiment can also be rearranged or adjusted in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for clearly describing a particular embodiment and do not imply that they represent the necessary components and / or order.
[0032] The serial numbers assigned to components in this document, such as "first" and "second," are used only to distinguish the described objects and have no sequential or technical meaning. The terms "connection" and "linkage" used in this application, unless otherwise specified, include both direct and indirect connections (linkages).
[0033] like Figure 1 and Figure 2As shown, this application provides an atomizing device, which includes a housing 10, with a mouthpiece 20 mounted on one end of the housing 10. An atomizer 30 and a bracket 40 for mounting a battery unit are disposed within the housing 10, and a sealing structure 50 is disposed between the atomizer 30 and the mouthpiece 20. It should be noted that... Figure 1 and Figure 2 In this paper, only some of the structure and components of the atomizing device are shown; components such as the battery unit, controller, and heater in atomizer 30 are not shown.
[0034] Please refer to Figure 1 and Figure 2 The atomizer 30 includes an oil cup 31 with an open bottom. An oil cup bottom cover 32 is provided to seal the open bottom. An oil cup cotton 33 is provided inside the oil cup 31, which serves as a liquid storage component to store the atomizing matrix.
[0035] The oil-storing cotton 33 has an atomization channel 331 in the middle. A heater can be installed in the atomization channel 331. When the heater is working, it can heat the atomization matrix adsorbed and stored in the oil-storing cotton 33 into an aerosol. Correspondingly, the top wall of the oil cup 31 has an air outlet 311. During suction, the airflow can carry the aerosol generated in the atomization channel 331 through the air outlet 311 to the suction nozzle 20.
[0036] Please refer to the structure of nozzle 20 Figure 1 , Figure 2 and Figure 3 In some embodiments, the mouthpiece 20 includes an inner tube 21 and an outer shell 22. The inner cavity of the inner tube 21 forms an airflow channel 23 through which airflow passes. The airflow channel 23 is connected to the air outlet 311 of the atomizer 30, so that the airflow can carry aerosol through the airflow channel 23 and be inhaled by the user.
[0037] The top of the outer shell 22 is connected to the top of the inner tube 21. From the top to the bottom, the outer shape and inner cavity size of the outer shell 22 gradually increase, and the width in the left-right direction is greater than the thickness in the front-back direction. Thus, the outer shell 22 and the inner tube 21 form an annular cavity 25 with an opening 24 at the bottom, at least at the bottom. The size of the cavity 25 gradually increases from the top to the bottom, and the left-right dimension of the annular cavity 25 is greater than the front-back dimension. The cavity 25 is isolated from the airflow channel 23. The suction nozzle 20 is mounted on the housing 10 via the outer shell 22.
[0038] In other embodiments, the outer shell 22 of the suction nozzle 20 can also be a cylindrical shape with a constant inner and outer diameter from top to bottom. The top end is connected to the top end of the inner tube 21 via an annular structure, thus forming an annular cavity 25 between the outer shell 22 and the inner tube 21. Of course, the cavity 25 between the outer shell 22 and the inner tube 21 can be partially filled, thus making the cavity 25 semi-annular.
[0039] Please refer to Figure 1 The sealing structure 50 is disposed between the atomizer 30 and the mouthpiece 20. The top end of the sealing structure 50 is sealed to the mouthpiece 20 to block the opening 24 and seal the cavity 25 of the mouthpiece 20 into the sensing chamber 26. The bottom end of the sealing structure 50 is sealed to the top end of the oil cup 31.
[0040] Please refer to Figure 1 and Figure 4 The sealing structure 50 has a sealing structure channel 51 in the middle, which serves as a connecting hole and communicates with the airflow channel 23. The inner tube 21 of the nozzle 20 is inserted into the sealing structure channel 51 and seals with the sealing structure 50, thus achieving a sealed connection between the sealing structure channel 51 and the airflow channel 23. The other end of the sealing structure channel 51 is connected to the air outlet 311 of the atomizer 30, thereby achieving a connection between the airflow channel 23 and the air outlet 311 of the atomizer 30.
[0041] The sealing structure 50 is also provided with a mounting cavity 52, which is combined with Figure 1 and Figure 5 As shown, a sensing element 60 is installed within the mounting cavity 52. The sensing element 60 is capable of sensing changes in air pressure within the sensing chamber 26. Those skilled in the art will understand that the sensing element 60 can be connected to the controller of the atomizing device for signal transmission. The sensing element 60 generates an electrical signal by sensing changes in air pressure within the sensing chamber 26, and transmits this signal to the controller, causing the controller to start and stop the atomizer 30. The sensing element 60 can be a microphone.
[0042] Please refer to Figure 4 , Figure 5 and Figure 6 As shown, the sealing structure 50 is also provided with a sensing airway 53, which connects the sensing chamber 26 and the sealing structure channel 51 to achieve communication between the sensing chamber 26 and the airflow channel 23. The sensing airway 53 is connected to the airflow channel 23 outside the sensing chamber 26. When the user inhales through the nozzle 20, an airflow is formed in the sealing structure channel 51 and flows towards the nozzle 20. This airflow can then be drawn into the sensing chamber 26 through the sensing airway 53, causing a drop in air pressure inside the sensing chamber 26. The sensing element 60 senses the user's inhalation action by sensing the change in air pressure inside the sensing chamber 26.
[0043] Since the sensing airway 53 is located on the sealing structure 50 that seals with the mouthpiece 20, the sensing airway 53 is closer to the mouthpiece 20, shortening the length of the sensing airway 53. When the user inhales, the sensing element 60 can quickly sense the inhalation action, making the atomizing device more sensitive and improving the response speed of the atomizing device.
[0044] In actual use, changes in the external environment, such as temperature and air pressure, can trigger the sensing element 60. Furthermore, children may accidentally use the nebulizer. To prevent accidental activation, the ports connecting the mounting cavity 52 and the sensing chamber 26, and the ports connecting the sensing airway 53 and the sensing chamber 26, are located on both sides of the outer periphery of the airflow channel 23. This arrangement, with the ports on the left and right sides of the airflow channel 23 respectively, extends the airflow path between the mounting cavity 52 and the sensing airway 53. Combined with the buffering effect of the sensing chamber 26, a certain suction force is required to trigger the sensing element 60, increasing the difficulty of accidental activation. Taking accidental use by a child as an example, children have lower lung capacity, and the above design makes it more difficult for a child's suction action to trigger the sensing element 60. Of course, in other embodiments, the port connecting the mounting cavity 52 to the sensing chamber 26 and the port connecting the sensing airway 53 to the sensing chamber 26 can also be located on the same side of the outer periphery of the airflow channel 23.
[0045] Regarding the structure of the sensing airway 53, as follows: Figure 5 and Figure 6 As shown, a groove is provided on the side of the sealing structure 50 facing away from the sensing chamber 26. The groove is connected to the channel 51 of the sealing structure. At the same time, a connecting channel 531 is provided on the sealing structure 50. The connecting channel 531 connects the sensing chamber 26 to the groove. The connecting channel 531 and the groove form a sensing air passage 53.
[0046] In one embodiment, the groove includes a surrounding groove section 532 that surrounds the sealing structure channel 51. The groove wall of the surrounding groove section 532 has a first communication port 533 that communicates with the sealing structure channel 51. Two or more first communication ports 533 are spaced apart along the circumference of the sealing structure channel 51. This allows for multi-point suction of gas in the sensing airway 53 during suction, ensuring the speed at which the sensing airway 53 responds to the suction action. The groove also includes a connecting groove section 534 that connects the surrounding groove section 532 and the connecting channel 531. The communication port between the connecting groove section 534 and the surrounding groove section 532 is a second communication port 535.
[0047] The second connecting port 535 and the first connecting port 533 are offset in the circumferential direction of the sealing structure channel 51. Thus, after each suction is completed, due to the low air pressure in the sensing chamber 26, the aerosol-containing airflow in the sealing structure channel 51 will flow back into the sensing air channel 53. After the backflowing airflow enters the winding groove section 532 through the first connecting port 533, it will not flow directly to the connecting groove section 534 through the second connecting port 535, which increases the resistance of the backflowing airflow into the sensing air channel 53.
[0048] In some embodiments, two connecting channels 531 are provided to connect the groove and the sensing chamber 26. Each of the two connecting channels 531 is connected to the surrounding groove segment 532 through a corresponding connecting slot segment 534. In this way, multiple airflow channels are formed in the sensing air passage 53. If one connecting channel 531 or connecting slot segment 534 is blocked, the airflow can still flow through other connecting channels 531 and connecting slot segments 534, forming a double-safety structure. At the same time, the two connecting channels 531 are connected by a groove 536. Thus, if one connecting slot segment 534 is blocked, the connecting channel 531 corresponding to the blocked connecting slot segment 534 can be connected to the other connecting channel 531 and the other connecting slot segment 534 through the groove 536, ensuring that both connecting channels 531 can work. The depth of the groove 536 is less than the depth of the groove, so that the airflow preferentially flows through the channels formed by the connecting channels 531 and connecting slot segments 534.
[0049] Two connecting slots 534 and corresponding connecting channels 531 are connected to the sensing chamber 26, forming two chamber connecting segments. A series of first connecting ports 533 around the slots 532 connect to the sealing structure channel 51 and the airflow channel 23, forming multiple channel connecting segments. These multiple chamber connecting segments and multiple channel connecting segments combine to form multiple airflow channels, making the sensing airway 53 a branched airway. In other embodiments, the flow channel shape within the branched airway can also be X, H, or other interconnected structures. There can be more than two chamber connecting segments and two more channel connecting segments, ensuring that the sensing airway 53 has reliable ventilation performance.
[0050] Of course, in order to ensure reliable communication between the sensing chamber 26 and the airflow channel 23, two or more non-connected sensing airways 53 can be provided on the sealing structure 50. If any sensing airway 53 is blocked, the connection between the sensing chamber 26 and the airflow channel 23 can still be achieved through other sensing airways 53. Any sensing airway 53 can be the branched airway described above.
[0051] The openings connecting the mounting cavity 52 and the sensing chamber 26, and the openings connecting the sensing air passage 53 and the sensing chamber 26, are located on both sides of the airflow channel 23. The sensing chamber 26 is annular around the airflow channel 23. Therefore, two air passages connecting the mounting cavity 52 and the sensing air passage 53 are also formed in the sensing chamber 26, achieving double protection to ensure the connection between the mounting cavity 52 and the sensing air passage 53.
[0052] Please refer to Figure 1 and Figure 5 The groove opening is covered by a first liquid-absorbing element 70, which absorbs condensate from the airflow passing through the groove, preventing condensate from entering the sensing chamber 26 and contaminating the sensing element 60. In other embodiments, the first liquid-absorbing element 70 can also plug the groove opening. The first liquid-absorbing element 70 can be oil-absorbing cotton or other materials capable of absorbing condensate.
[0053] In one embodiment, the sealing structure 50 is a split structure, comprising a top first portion 501 and a bottom second portion 502. A mounting cavity 52 is disposed on and extends through the first portion 501, allowing the sensing element 60 to sense the negative pressure within the sensing chamber 26 via its upper opening. The opposing end faces of the first portion 501 and the second portion 502 form an atmospheric channel 54. The atmospheric channel 54 has an atmospheric connection port 541 located on the surface of the sealing structure 50, connecting the mounting cavity 52 to the atmospheric environment within the housing 10, enabling the corresponding side of the sensing element 60 to sense atmospheric pressure. The split structure of the sealing structure 50 facilitates manufacturing and installation of the sensing element 60 within the mounting cavity 52. The sealing structure 50 can be made of silicone, rubber, or other suitable materials for sealing.
[0054] Please refer to Figure 1 and Figure 7 A second liquid-absorbing element 80 is provided on the top surface of the sealing structure 50 to absorb condensate entering the sensing chamber 26. The top surface of the sealing structure 50 has an annular flange 55 that partially encloses the sealing structure channel 51. The inlet of the sensing air passage 53 on the top surface of the sealing structure 50 is an air passage connection port 57. A baffle 56 is provided between the air passage connection port 57 and the annular flange 55. The groove between the baffle 56 and the annular flange 55 forms a mounting groove for installing the second liquid-absorbing element 80. The second liquid-absorbing element 80 is installed in this mounting groove, and the baffle 56 forms one side wall of the mounting groove. The opening of the mounting cavity 52 that communicates with the sensing chamber 26 is a connecting cavity opening. The second liquid-absorbing element 80 can be oil-absorbing cotton or other materials capable of absorbing condensate. The second liquid-absorbing element 80 is provided to prevent the forward and reverse blowing of gas and condensate from affecting the sensing element 60.
[0055] The baffle 56 has a notch-shaped passage 561, which facilitates airflow through the second liquid-absorbing member 80, allowing the second liquid-absorbing member 80 to absorb more liquid. In addition, the front and rear ends of the baffle 56 are bent toward the air passage connection 57, forming a guiding structure that guides the airflow entering the sensing chamber 26 through the air passage connection 57 toward the second liquid-absorbing member 80.
[0056] like Figure 2 As shown, the housing 10 includes a front cover 11, a middle frame 12, and a rear cover 13. The front cover 11 and the middle frame 12 are fastened together to form an inner cavity for mounting corresponding components, and the rear cover 13 is fastened to the rear side of the middle frame 12. The atomizing device also includes a third liquid-absorbing element 90 located at the bottom end of the support 40 for absorbing liquid entering the housing 10. Similar to the first liquid-absorbing element 70 and the second liquid-absorbing element 80, the third liquid-absorbing element 90 can be oil-absorbing cotton or other materials capable of absorbing liquid.
[0057] 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.
