Description

Technical Field

[0001] The present application relates to the technical field of atomization equipment, and in particular to an atomizer and an electronic atomization device. Background Art

[0002] The airway structure design within an electronic atomizer directly impacts device functionality and user experience. Currently, the atomizer airway in electronic atomizers typically adopts a bottom-through layout, for example, placing the atomizer airway directly below or to the side of the heating element.

[0003] In actual use, the device is prone to leakage from the liquid reservoir or condensate backflow. Because the atomizing airway is located low, gravity forces the liquid to flow down the airway and accumulate, eventually blocking the airway holes, increasing suction resistance or even causing complete failure. Furthermore, if leaked liquid flows into the circuit board area, it could cause a short circuit. This atomizing airway structure suffers from insufficient reliability. Summary of the Invention

[0004] In order to improve the problem that the atomizing airway is easily blocked by leaking liquid and to improve the reliability of the airway structure, the present application provides a new atomizer and an electronic atomizing device.

[0005] According to the first aspect, an embodiment provides an atomizer, comprising:

[0006] The housing has a first direction, and one end of the housing along the first direction has a nozzle setting position;

[0010] The air inlet passage is provided with an air inlet communicating with the outside of the housing, and the air inlet is located between the buffer cavity and the nozzle setting position in the first direction, so as to prevent the atomized liquid from blocking the air inlet before filling the buffer cavity when the atomizer is in a posture with the nozzle setting position facing upward;

[0011] The discharge channel extends to the nozzle setting position to allow the aerosol in the buffer cavity to be discharged.

[0012] In one embodiment, the shell has a second direction perpendicular to the first direction, the cache cavity is arranged along the second direction, the air intake channel and the exhaust channel are located on opposite sides of the cache cavity along the second direction, and the air intake channel and the exhaust channel both extend in a direction parallel to the first direction.

[0013] In one embodiment, the housing includes a main body and a blocking seat, the heating element is disposed in the main body, and the blocking seat is disposed at one end of the main body along the first direction and is spaced apart from the heating element to form the buffer cavity between the heating element and the blocking seat;

[0014] The main body is provided with hole structures on both sides of the heating element along the second direction to form the air inlet channel and the air outlet channel respectively.

[0015] In one embodiment, the air inlet is located on one side of the heating element along the second direction, and is closer to the suction nozzle than the heating element in the first direction.

[0016] In one embodiment, the air inlet is arranged on the channel wall of the air inlet channel away from the heating element, and a guide structure is provided on the channel wall of the air inlet channel facing the air inlet, for guiding the airflow entering from the air inlet to flow toward the heating element.

[0017] In one embodiment, the guide structure includes a guide slope located on the channel wall of the air inlet channel toward the air inlet, and the guide slope gradually approaches the heating element in the second direction from an end away from the cache cavity to an end close to the cache cavity.

[0018] In one embodiment, a liquid storage tank for storing atomized liquid is provided on the cavity wall of the buffer cavity on the side facing the suction nozzle.

[0019] In one embodiment, the atomizer further comprises an airflow sensor and a sensing airway, wherein the sensing airway has a first end communicating with the airflow sensor and a second end communicating with the exhaust channel;

[0020] The airflow sensor is located on a side of the sensing airway close to the nozzle setting position in the first direction, and the distance between the first end and the nozzle setting position in the first direction is no greater than the distance between the second end and the nozzle setting position in the first direction, so as to limit the atomized liquid from contacting the airflow sensor before filling the sensing airway when the atomizer is in a posture with the nozzle setting position facing upward.

[0021] In one embodiment, the airflow sensor is arranged on a side of the atomizer close to the nozzle arrangement position, and the sensing airway is connected to an end of the exhaust channel close to the nozzle arrangement position.

[0028] According to the atomizer of the above embodiment, a cache cavity is provided on the side of the heating element away from the nozzle setting position, so as to constitute the atomizing air duct of the atomizer together with the air inlet channel and the exhaust channel. Since the air inlet of the air inlet channel is located between the cache cavity and the nozzle setting position, when the atomizer is in a posture with the nozzle setting position facing upward, the position of the air inlet is higher than the position of the cache section; if the air inlet is to be blocked, the cache section needs to be filled with leaked or condensed atomized liquid, and in actual use, large-scale leakage rarely occurs. Therefore, the coordinated arrangement of the air inlet and the cache cavity helps to improve the problem that the atomizing air duct is easily blocked by leaking liquid, which is beneficial to improving the reliability of the air duct structure.

[0042] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0043] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0044] The serial numbers assigned to components herein, such as "first," "second," etc., are used solely to distinguish the objects being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0045] The atomizing air channel 130 in the electronic atomizing device usually adopts a bottom straight-through layout. For example: please refer to Figure 1 , is a schematic diagram of the cross-sectional structure of an electronic atomization device in the related art. In the device, the air inlet duct is directly arranged below the heating element 120 in the illustrated perspective. The air flow enters from the bottom of the electronic atomization device, flows through the gaps between the various components in the device to the atomizer 100, and enters the atomizer 100 through the air inlet channel 131, carrying away the aerosol generated by the heating element 120 and discharging it.

[0046] Please refer to Figure 2 , is a schematic diagram of the cross-sectional structure of another electronic atomization device in the related art, in which the air inlet channel 131 is arranged on the lower side of the heating element 120 as viewed from the perspective of the diagram.

[0047] Regardless of whether the air inlet channel 131 is located directly below or to the side of the heating element 120, if atomized liquid leaks or condenses and flows back, the atomized liquid will flow downward along the airway under the action of gravity, accumulating at low points and eventually causing airway blockage, increasing suction resistance or even complete failure. Furthermore, if the atomized liquid flows into the circuit board area, it may cause a short circuit in the device.

[0048] In an embodiment of the present application, a buffer chamber 132 is provided on the side of the heating element 120 away from the nozzle setting position 111. While being used to buffer aerosols, it can also be used to buffer leaked or condensed refluxed atomized liquid. The air inlet 1311 is provided between the buffer chamber 132 and the nozzle setting position 111, so that when the atomizer 100 is in a use posture with the nozzle setting position 111 facing upward, the air inlet 1311 is located above the buffer chamber 132, and the atomized liquid needs to completely fill the buffer chamber 132 to block the air inlet 1311. Since large amounts of liquid leakage rarely occur in actual use, the coordinated provision of the air inlet 1311 and the buffer chamber 132 helps to improve the problem that the atomizing airway 130 is easily blocked by leaking liquid, which is beneficial to improving the reliability of the airway structure.

[0049] Examples of the atomizer in the embodiments of this application:

[0050] In one embodiment, please refer to Figure 3 and Figure 4 The atomizer includes: a shell 110, a heating element 120, a buffer chamber 132, an air inlet channel 131 and an exhaust channel 133.

[0051] The housing 110 is a main component constituting the outer contour of the atomizer 100. Figure 3 , the shell 110 has a first direction, and one end of the shell 110 along the first direction has a nozzle setting position 111. For ease of understanding, the first direction can be understood as the height direction of the atomizer 100 in the illustrated perspective; of course, other directions can also be regarded as the first direction. The nozzle setting position 111 can be understood as the position of the shell 110 for connecting the nozzle, or it can be understood as the position where the shell 110 is provided with a nozzle; that is, the shell 110 can include the nozzle, or it can be connected to the nozzle by adding a nozzle. The following is an example of an embodiment in which the shell 110 is not provided with a nozzle.

[0052] Please refer to Figure 4 The heating element 120 can be understood as a heating element or a combination of a heating element and a heat conducting element in the atomizer 100. The heating element 120 is disposed within the housing 110 and is used to heat the atomized liquid to generate an aerosol. The heating method and specific structure of the heating element 120 are not limited, as long as it can be used to heat the atomized liquid to generate an aerosol.

[0053] In one embodiment, please refer to Figure 4 The atomizer 100 further includes a liquid storage tank 140 , which is located on a side of the heating element 120 close to the nozzle setting position 111 and is used to supply atomized liquid to the heating element 120 .

[0054] In one embodiment, please refer to Figure 4 The housing 110 may include a main body 112, in which a liquid storage tank 140 is disposed. The heating element 120 is disposed on a side of the liquid storage tank 140 facing away from the nozzle setting position 111 and is in communication with the liquid storage tank 140. This allows the atomized liquid stored in the liquid storage tank 140 to be continuously supplied to the heating element 120. In particular, when the atomizer 100 is in a position facing the nozzle setting position 111, the heating element 120 is located below the liquid storage tank 140. The atomized liquid in the liquid storage tank 140 is actively transported to the heating element 120 under the action of gravity, thereby being heated to generate an aerosol.

[0055] Please refer to Figure 4The buffer chamber 132 is provided in the housing 110 and is provided on the side of the heating element 120 away from the nozzle location 111, for buffering the aerosol generated by the heating element 120. It is understood that the buffer chamber 132 can also be used to buffer the aerosol liquid leaking from the liquid storage tank 140 or the aerosol liquid condensing and flowing back.

[0056] In one embodiment, please refer to Figure 4 The housing 110 further includes a blocking seat 113, which is disposed at the other end of the main body 112 along the first direction, i.e., the end of the main body 112 away from the nozzle location 111. The blocking seat 113 is spaced apart from the heating element 120 to form a buffer cavity 132 between the heating element 120 and the blocking seat 113.

[0057] The heating element 120 may have an aerosol output end 121 on a side away from the liquid storage tank 140 . The aerosol output end 121 is connected to the buffer cavity 132 so that the aerosol generated by the heating element 120 can enter the buffer cavity 132 for temporary storage.

[0058] In one embodiment, please refer to Figure 4 The blocking seat 113 may be a silicone member provided with conductive members such as conductive columns and conductive needles. The conductive members may be electrically connected to the heating element 120 through a conductive line so as to supply power to the heating element 120 .

[0059] In one embodiment, please refer to Figure 4 An air inlet channel 131 and an exhaust channel 133 are provided in the shell 110 to cooperate with the cache cavity 132. The air inlet channel 131 and the exhaust channel 133 are both connected to the cache cavity 132, and the cache cavity 132 is located between the air inlet channel 131 and the exhaust channel 133, so that the cache cavity 132, the air inlet channel 131 and the exhaust channel 133 together form the atomization air channel 130 of the atomizer 100.

[0060] Among them, please refer to Figure 3 and Figure 4 , the air inlet channel 131 is provided with an air inlet 1311 connected to the outside of the shell 110, and the air inlet 1311 can be set on the main body 112 and exposed to the outside of the main body 112. The air inlet 1311 is located between the buffer cavity 132 and the suction nozzle setting position 111 in the first direction. When the atomizer 100 is in a use posture with the suction nozzle setting position 111 facing upward, the buffer cavity 132 is located below the air inlet 1311. The atomized liquid needs to fill the buffer cavity 132 before it can block the air inlet 1311, which helps to reduce the risk of blockage of the atomizing airway 130 and improve the reliability of the airway structure. The exhaust channel 133 extends to the suction nozzle setting position 111 so as to be connected to the suction nozzle portion 340 located at the suction nozzle setting position 111 (such as Figure 5 as shown), so that the aerosol in the buffer cavity 132 can be discharged.

[0061] When the atomizer 100 is in use, external airflow is sucked into the air inlet channel 131 through the air inlet 1311 and then enters the buffer chamber 132 , taking away the aerosol generated by the heating element 120 through the aerosol output end 121 and discharged through the discharge channel 133 .

[0062] In one embodiment, please refer to Figure 4 A liquid storage tank 1321 for storing atomized liquid is provided on the cavity wall of the cache cavity 132 facing the nozzle setting position 111, so as to further increase the storage capacity of the cache cavity 132 and reduce the possibility of the cache cavity 132 being filled with atomized liquid, thereby improving the anti-blocking performance of the atomizing airway 130.

[0063] Exemplarily, a liquid storage tank 1321 is provided on the cavity wall of the cache cavity 132 close to the air inlet channel 131. The liquid storage tank 1321 can be located on the blocking seat 113 so that the atomized liquid entering the cache cavity 132 will first converge in the liquid storage tank 1321, and then continue to converge in the cache cavity 132 after the liquid storage tank 1321 is filled.

[0064] In one embodiment, the housing 110 further has a second direction perpendicular to the first direction. For ease of understanding, the second direction can be understood as Figure 4 The left and right directions of the atomizer 100 are shown. Figure 4 The cache cavity 132 is arranged along the second direction so that the axial direction of the cache cavity 132 is roughly parallel to the second direction.

[0065] The air inlet channel 131 and the exhaust channel 133 are located on opposite sides of the buffer cavity 132 along the second direction. Both the air inlet channel 131 and the exhaust channel 133 extend parallel to the first direction. For example, the main body 112 is provided with a hole structure on both sides of the heating element 120 along the second direction to form the air inlet channel 131 and the exhaust channel 133, respectively. As a result, the air inlet channel 131, the buffer cavity 132, and the exhaust channel 133 form a U-shaped atomization air channel 130.

[0066] The U-shaped atomizing airway 130, compared to a straight-through bottom-mounted atomizing airway 130, helps reduce the overall length of the airway in the electronic atomizing device. This shortens the distance the aerosol travels from generation to discharge, helping to maintain aerosol temperature and reduce aerosol flavor degradation, thereby maintaining a consistent puff experience. Furthermore, since the airway does not need to pass through numerous internal components, it helps reduce whistling and other unusual sounds caused by airflow, further enhancing the user experience.

[0067] In one embodiment, please refer to Figure 4 The air inlet 1311 can be located on one side of the heating element 120 along the second direction and closer to the nozzle setting position 111 than the heating element 120 in the first direction. Figure 4 The upper side of the heating element 120 in the perspective shown helps to further reduce the risk of blockage of the air inlet 1311.

[0068] In one embodiment, please refer to Figure 4 The air inlet 1311 is arranged on the channel wall of the air inlet channel 131 on the side away from the heating element 120, and a guide structure 1312 is provided on the channel wall of the air inlet channel 131 facing the air inlet 1311, which is used to guide the airflow entering from the air inlet 1311 to flow toward the heating element 120, so that the aerosol generated by the heating element 120 can be fully carried away by the air inlet airflow, which helps to enhance the fullness of the discharged aerosol, make the aerosol fragrant, and thus improve the smoking taste.

[0069] In one embodiment, the air inlet 1311 may be an air inlet hole provided on the channel wall of the air inlet channel 131 on the side away from the heating element 120. The flow guiding structure 1312 includes a flow guiding slope located on the channel wall of the air inlet channel 131 facing the air inlet 1311. The flow guiding slope gradually approaches the heating element 120 in the second direction from the end away from the buffer cavity 132 to the end close to the buffer cavity 132, so that the air flow is guided into the buffer cavity 132 along the cavity wall of the buffer cavity 132 on the side close to the heating element 120.

[0070] It can be understood that the specific setting method and setting position of the guide structure 1312 are not limited; for example, it can also be a guide surface, guide groove or other guide structure set on the channel wall of the air inlet channel 131 on the side close to the heating element 120, as long as it can meet the guide requirements.

[0071] When the electronic atomizer is used, the inhalation action triggers airflow, which in turn activates the airflow sensor 150 in the electronic atomizer. Once the airflow sensor 150 is activated, the heating element 120 receives voltage and starts heating, thereby generating aerosol. If the airflow sensor 150 comes into contact with the atomized liquid, it is easily contaminated and becomes inoperable.

[0072] In this regard, in one embodiment, please refer to Figure 3 and Figure 4 The atomizer 100 further includes an airflow sensor 150 and an inductive airway 151. The inductive airway 151 has a first end 1511 communicating with the airflow sensor 150 and a second end 1512 communicating with the exhaust channel 133. The airflow sensor 150 is used to detect the inhalation action and trigger the heating element 120 to work.

[0073] Among them, the distance between the first end 1511 and the nozzle setting position 111 in the first direction is no greater than the distance between the second end 1512 and the nozzle setting position 111 in the first direction, so that when the atomizer 100 is in a posture with the nozzle setting position 111 facing upward, the first end 1511 is no lower than the second end 1512, thereby limiting the atomized liquid from contacting the airflow sensor 150 before filling the sensing airway 151.

[0074] The airflow sensor 150 can be located on the side of the sensing air channel 151 close to the nozzle setting position 111 in the first direction, and the sensing air channel 151 is connected to one end of the exhaust channel 133 close to the nozzle setting position 111, so that the airflow sensor 150 is as far away from the buffer cavity 132 as possible, further reducing the risk of the airflow sensor 150 failing due to contact with the atomized liquid.

[0075] For example, please refer to Figure 4 The main body 112 has a protruding portion 1121 on one side thereof along the first direction, close to the nozzle setting position 111. The housing 110 further includes a sealing member 114, which is located at one end of the main body 112 along the first direction away from the blocking seat 113. The nozzle setting position 111 is formed on the sealing member 114. The sealing member 114 has a mounting portion 1141 mounted on the protruding portion 1121. The airflow sensor 150 is mounted in the mounting portion 1141, and a gap is defined between the protruding portion 1121 and the mounting portion 1141, generally along the second direction, to form a sensing airway 151.

[0076] Please refer to Figure 4 In the sensing air channel 151, the surface of the protruding portion 1121 facing the mounting portion 1141 may be provided with a protruding liquid retaining platform 1122. The liquid retaining platform 1122 is located on the side of the sensing air channel 151 near the discharge channel 133. The surface of the mounting portion 1141 facing the protruding portion 1121 may be provided with a recessed cavity 1142 corresponding to the liquid retaining platform 1122, thereby forming a retaining structure that restricts the flow of atomized liquid toward the side of the sensing air channel 151 near the airflow sensor 150 and allows airflow to pass through, thereby further reducing the risk of failure of the airflow sensor 150.

[0077] It should be noted that the “extending along the first / second direction” mentioned in the above embodiments includes being arranged along a direction parallel or substantially parallel to the first / second direction.

[0078] Examples of the electronic atomization device in this application:

[0079] In one embodiment, please refer to Figure 5 The electronic atomizing device includes an atomizer 100 and a power supply assembly 200 as in any of the above embodiments, and the power supply assembly 200 is used to supply power to the atomizer 100.

[0080] The power supply assembly 200 can be understood as a battery cell or a collection of battery cells and related components such as a circuit board. The power supply assembly 200 can be fixedly connected to the atomizer 100 or detachably connected. If the power supply assembly 200 and the atomizer 100 are detachably connected, the atomizer 100 and the power supply assembly 200 can be replaced depending on usage.

[0081] In one embodiment, please refer to Figure 5 and Figure 6 The electronic atomization device further includes a device housing 300, in which the atomizer 100 is disposed, and the power supply assembly 200 may also be disposed. The device housing 300 has a hollow structure 350 that communicates with the outside. The hollow structure 350 is staggeredly connected to the air inlet 1311 of the atomizer 100 to reduce the whistling sound during inhalation through a circuitous airflow path. The device housing 300 between the hollow structure 350 and the air inlet 1311 can also limit the propagation of the generated airflow sound, while reducing the risk of external dust directly entering the interior of the atomizer 100.

[0082] Exemplarily, the device housing 300 includes a middle frame 310, a front cover 320 and a rear cover 330 arranged on both sides of the middle frame 310, and a mouthpiece 340 installed at one end of the middle frame 310 along the first direction. The hollow structure 350 can be an air guide hole, which is arranged on the front cover 320. The air inlet 1311 is located on one side of the atomizer 100 along the second direction and is arranged toward the middle frame 310 to form a misalignment with the hollow structure 350. There is an air guide gap between the outer surface of the atomizer 100 and the inner surface of the device housing 300, so that the hollow structure 350 and the air inlet 1311 are connected, and air flow can enter the interior of the device housing 300 from the hollow structure 350, and then enter the atomizer 100 through the air inlet 1311 after flowing through the air guide gap. Compared with the method of setting the hollow structure 350 and the air inlet 1311 directly opposite each other, it helps to reduce the air flow sound when the device is in use.

[0083] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For those skilled in the art of the present application, based on the concept of the present application, they can also make some simple deductions, modifications or substitutions.
