Description

TECHNICAL FIELD

[0001] The present invention relates to the field of atomization technologies, and more particularly, to a mouthpiece assembly, an atomization device and an electronic atomizer.BACKGROUND

[0002] An electronic atomizer refers to a device used to heat atomization liquids so as to atomize the atomization liquids into aerosols. The aerosols formed by atomizing the atomization liquid may be used for a user to inhale.

[0003] The electronic atomizer may generally include an atomization device and a power supply unit, the power supply unit is used to supply power to the atomization device, and the atomization device is used to heat the atomization liquids and atomize the atomization liquids into aerosols.

[0004] The power supply unit may include a housing, a circuit board arranged in the housing, a battery arranged in the housing and electrically connected to the circuit board, and an air pressure sensing element arranged on the circuit board. The atomization device is provided with a startup airflow path, and the startup airflow path is interconnected with the air pressure sensing element. When the electronic atomizer is used, the user inhales air through the startup airflow path, and air pressure around the air pressure sensing element changes. The air pressure sensing element may sense an air pressure change and transmit an air pressure change signal back to the circuit board. The circuit board may control the battery to supply power to the atomization device based on the air pressure change signal. In this way, the atomization device implements an inhalation startup effect, in order to perform an atomization operation to atomize the atomization liquids into the aerosols.

[0005] In some cases, the startup airflow path has an opening exposed to an external environment, and the user is enabled to suck the startup airflow path through the opening. However, condensation is prone to occur at the opening of the startup airflow path, and the condensate liquid formed by condensation is prone to flow to the air pressure sensing element through the startup airflow path. Due to this reason, the use of the air pressure sensing element is influenced, and the inhalation startup effect of the atomization device is affected accordingly.

DETAILED DESCRIPTION OF EMBODIMENTS

[0032] The present invention is described in detail below with reference to the accompanying drawings and the embodiments.

[0033] With reference to FIGS. 1-3 and in combination with other drawings, FIG. 1 is a three-dimensional structural diagram of an atomization device 100 in accordance with some embodiments of the present invention, FIG. 2 is a cross-sectional view of FIG. 1 along A-A, and FIG. 3 is an enlarged view of part B in FIG. 2. The mouthpiece assembly 10 provided in the embodiments of the present invention is provided with an aerosol emission airflow path 102 and a startup airflow path 101. One end of the aerosol emission airflow path 102 is arranged to face the atomization core 20 in a first direction Y, and one end of the aerosol emission airflow path 102 away from the atomization core 20 is configured to be interconnected with an outside of the mouthpiece assembly 10. An air inlet of the startup airflow path 101 is configured to be interconnected with the outside of the mouthpiece assembly 10, the startup airflow path 101 and the aerosol emission airflow path 102 are spaced apart from each other along a second direction X, and the startup airflow path 101 and the aerosol emission airflow path 102 are interconnected. The first direction Y and the second direction X are intersected.

[0034] Both the aerosol emission airflow path 102 and the startup airflow path 101 are airflow paths and flow paths in the mouthpiece assembly 10.

[0035] The aerosol emission airflow path 102 has an air inlet and an air outlet.

[0036] The air inlet of the aerosol emission airflow path 102 refers to an end of the aerosol emission airflow path 102 used for allowing gas to flow into the aerosol emission airflow path 102, this air inlet is a part of the end of the aerosol emission airflow path 102, rather than an end point or an end surface. One end of the aerosol emission airflow path 102 is the air inlet of the aerosol emission airflow path 102, and this end of the aerosol emission airflow path 102 is arranged to face the atomization core 20 in the first direction Y. Specifically, the air inlet of the aerosol emission airflow path 102 may be at least used for an aerosol formed by atomization at the atomization core 20 to flow into the aerosol emission airflow path 102 through the air inlet of the aerosol emission airflow path 102.

[0037] The air outlet of the aerosol emission airflow path 102 refers to an end of the aerosol emission airflow path 102 used to allow the gas in the aerosol emission airflow path 102 to flow out of the mouthpiece assembly, this air outlet is a part of the end of the aerosol emission airflow path 102, rather than an end point or an end surface. One end of the aerosol emission airflow path 102 away from the atomization core 20 is the air outlet of the aerosol emission airflow path 102, and is configured to be interconnected with the outside of the mouthpiece assembly 10. That is, the air outlet of the aerosol emission airflow path 102 is interconnected with external space of the mouthpiece assembly 10. Specifically, the air outlet of the aerosol emission airflow path 102 may be at least used to allow the gas in the aerosol emission airflow path 102 to flow to the outside of the mouthpiece assembly 10. The external space of the mouthpiece assembly being interconnected with the air outlet of the aerosol emission airflow path 102 may be, but is not limited to, an external environment.

[0038] The startup air path 101 has an air inlet and an air outlet.

[0039] The air inlet of the startup airflow path 101 refers to an end of the startup airflow path 101 used for allowing air outside the mouthpiece assembly 10 to enter the startup airflow path 101, and this air inlet is a part of the end of the startup airflow path 101 instead of an endpoint or an end surface. The air inlet of the startup airflow path 101 is configured to be interconnected with the outside of the mouthpiece assembly 10, which means that the air inlet of the startup airflow path 101 may be interconnected with the external space of the mouthpiece assembly 10. After the mouthpiece assembly 10 and the power supply unit 200 of the electronic atomizer 1000 are assembled, the air inlet of the startup airflow path 101 may be interconnected with a through hole 2201 on a circuit board 220 in the power supply unit 200. That is, the external space of the mouthpiece assembly 10 interconnected with the air inlet of the startup airflow path 101 may be, but is not limited to, the through hole 2201 on the circuit board 220. In this way, air at the through hole 2201 may flow into the startup airflow path 101 through the air inlet of the startup airflow path 101 under the action of suction, and the air pressure around the air pressure sensing element 240 located at the through hole 2201 of the circuit board 220 changes accordingly. The specific structure of the power supply unit 200, the circuit board 220, the through hole 2201 and the air pressure sensing element 240 will be described below, and is not repeatedly described here.

[0040] The air outlet of the startup airflow path 101 refers to an end of the startup airflow path 101 used for allowing air to flow out, and this air outlet is a part of the end of the startup airflow path 101 instead of an endpoint or an end surface.

[0041] The startup airflow path 101 is interconnected with the aerosol emission airflow path 102, which means that the air outlet of the startup airflow path 101 is interconnected with the air inlet of the aerosol emission airflow path 102. Due to this arrangement, gas in the startup airflow path 101 may flow into the aerosol emission airflow path 102 through the air outlet of the startup airflow path 101 and the air inlet of the aerosol emission airflow path 102. One or a plurality of air inlets of the aerosol emission airflow path 102 may be provided, the outlet of the aerosol emission airflow path 102 arranged to face the atomization core 20 and the air inlet of the aerosol emission airflow path 102 configured to be interconnected with the startup airflow path 101 may be the same air inlet or be different air inlets.

[0042] The first direction Y refers to a general distribution direction of the aerosol emission airflow path 102 and the atomization core 20, and the second direction X refers to a general distribution direction of the aerosol emission airflow path 102 and the startup airflow path 101.

[0043] The first direction Y intersects with the second direction X indicates that the first direction Y and the second direction X may form an included angle greater than 0° and less than 180°, that is, the first direction Y is not parallel with the second direction X. The first direction Y and the second direction X may be perpendicular to each other, or may not be perpendicular. The first direction Y and the second direction X may be directions intersecting on the same plane, alternatively, the first direction Y and the second direction X may be directions on mutually different planes, and a projection of the second direction X on the plane which the first direction Y lies in may intersect with the first direction Y. As an example, the first direction Y is perpendicular to the second direction X. The first direction Y may be a height direction of the atomization device 100, and the second direction X may be a width direction of the atomization device 100.

[0044] According to the mouthpiece assembly 10 provided in the embodiments of the present invention, the air inlet of the startup airflow path 101 is arranged to be interconnected with the outside of the mouthpiece assembly 10, the startup airflow path 101 is interconnected with the aerosol emission airflow path 102, and one end of the aerosol emission airflow path 102 away from the atomization core 20 is configured to be interconnected with the outside of the mouthpiece assembly 10. Due to this arrangement, the air outlet of the startup airflow path 101 does not need to be directly interconnected with the outside of the mouthpiece assembly 10, but is indirectly connected to the outside of the mouthpiece assembly 10 through the aerosol emission airflow path 102. Thus, a problem that condensation is prone to occur at the air outlet of the startup airflow path 101, which causes the air pressure sensing element 240 to be damaged by moisture and thereby influencing the inhalation startup effect may be improved. In this way, a user may inhale through one end of the aerosol emission airflow path 102 away from the mouthpiece assembly 10, and air around the air pressure sensing element 240 may enter the startup airflow path 101 through the air inlet of the startup airflow path 101, and then flows into the aerosol emission airflow path 102, and flows out from an end of the aerosol emission airflow path 102 away from the atomization core 20, thereby achieving the inhalation startup effect. On this basis, the atomization core 20 may heat and atomize the atomization liquid to form aerosols, the aerosols may flow into the aerosol emission airflow path 102 and then flow to the outside of the mouthpiece assembly 10.

[0045] Since one end of the aerosol emission airflow path 102 is arranged to face the atomization core 20 in the first direction Y, the startup airflow path 101 and the aerosol emission airflow path 102 are spaced apart from each other in the second direction X, and the first direction Y intersects with the second direction X, such that the aerosol emission airflow path 102 and the startup airflow path 101 are arranged to be mutually staggered. In this way, when condensation occurs at one end of the aerosol emission airflow path 102 away from the atomization core 20, it is difficult for the generated condensate liquid to flow from the aerosol emission airflow path 102 to the startup airflow path 101, and thus it is difficult for the condensate liquid to flow to the air pressure sensing element 240 through the startup airflow path 10. For example, in case where the first direction Y is substantially the gravity direction, and the atomization core 20 is substantially located below the aerosol emission airflow path 102 along the gravity direction, the startup airflow path 101 and the aerosol emission airflow path 102 are generally staggered along the horizontal direction. In this way, when one end of the aerosol emission airflow path 102 away from the atomization core 20 is congealed, the generated condensate liquid may flow to the atomization core 20 under the action of gravity, and it is difficult for the condensate liquid to flow to the startup airflow path 101.

[0046] Due to this arrangement, a problem that the air pressure sensing element 240 is prone to being influenced by the condensate liquid may be improved, which causes the inhalation startup effect to be failed may be improved.

[0047] In some embodiments, with reference to FIGS. 1-3 and in combination with other drawings, one end of the aerosol emission airflow path 102 away from the atomization core 20 passes through one end of the mouthpiece assembly 10 in the first direction Y. Due to this arrangement, the air inlet and the air outlet of the aerosol emission airflow path 102 are opposite and interconnected in the first direction Y.

[0048] In this way, the user is facilitated to perform a suction operation.

[0049] In some embodiments, with reference to FIGS. 1-3 and in combination with other drawings, an air inlet of the start airflow path 101 passes through one end of the mouthpiece assembly 10 in the first direction Y.

[0050] Due to this arrangement, after the mouthpiece assembly 10 and the power supply unit 200 are assembled, it is convenient for the through hole 2201 on the circuit board 220 in the power supply unit 200 to be interconnected with the startup airflow path 101, and gas flow is facilitated.

[0051] In some embodiments, with reference to FIG. 2 and FIG. 3 and in combination with other drawings, the startup airflow path 101 is provided with a first air inlet 1011 and a first air outlet 1012 spaced apart from each other, the first air inlet 1011 is connected to the outside of the mouthpiece assembly 10. The aerosol emission airflow path 102 is provided with a second air inlet 1021 and a second air outlet 1022 spaced apart from each other. The second air outlet 1022 is connected to the outside of the mouthpiece assembly 10, and the second air inlet 1021 is interconnected with the first air outlet 1012. In the first direction Y, the second air inlet 1021 is located between the first air outlet 1012 and the atomization core 20.

[0052] The first air inlet 1011 and the first air outlet 1012 are arranged at two opposite ends of the startup airflow path 101, the first air inlet 1011 is arranged at the air inlet of the startup airflow path 101, and the first air outlet 1012 is arranged at the air outlet of the startup airflow path 101.

[0053] The second air inlet 1021 is an air inlet of the aerosol emission airflow path 102 configured to be interconnected with the startup airflow path 101, and is arranged at an air inlet of the aerosol emission airflow path 102. The second air outlet 1022 is arranged at an air outlet of the aerosol emission airflow path 102.

[0054] It may be appreciated that air at the through hole 2201 of the circuit board 220 of the power supply unit 200 may flow into the startup airflow path 101 through the first air inlet 1011 of the startup airflow path 101, and then enters the aerosol emission airflow path 102 through the first air outlet 1012 of the startup airflow path 101 and the second air inlet 1021 of the aerosol emission airflow channel 102, and finally flows out of the mouthpiece assembly 10 through the second air outlet 1022 of the aerosol emission airflow path 102.

[0055] In the first direction Y, the second air inlet 1021 is located between the first air outlet 1012 and the atomization core 20, the difficulty of flowing the condensate liquid from the aerosol emission airflow path 102 to the startup airflow path 101 is increased, a problem that the condensate liquid formed by condensation occurring at the aerosol emission airflow path 102 is prone to flow to the air pressure sensing element 240, thereby causing the air pressure sensing element 240 to be damaged by moisture may be further improved, and the inhalation startup effect of the electronic atomizer 1000 is further improved.

[0056] It should be supplementally explained that, when the first direction Y is substantially the direction of gravity, and the atomization core 20 is located substantially below the aerosol emission airflow path 102 in the direction of gravity, the atomization core 20 is substantially located below the second air inlet 1021 of the aerosol emission airflow path 102 in the direction of gravity, and the first air outlet 1012 of the startup airflow path 101 is located above the second air inlet 1021 in the direction of gravity. In this way, when one end of the aerosol emission airflow path 102 away from the atomization core 20 is congealed, the generated condensate liquid flows to the atomization core 20 under the action of gravity. Thus, it is difficult for the condensate liquid to flow upwards and thereby flowing to the startup airflow path 101 through the first air outlet 1012.

[0057] In some embodiments, with reference to FIG. 2 and FIG. 3 and in combination with other drawings, the second air inlet 1021 is disposed at one end of the aerosol emission airflow path 102 adjacent to the atomization core 20 in the first direction Y, and is arranged to face the atomization core 20 in the first direction Y.

[0058] It may be appreciated that the second air inlet 1021 is arranged at an air inlet of the aerosol emission airflow path 102 arranged to face the atomization core 20 in the first direction Y. That is, the air inlet of the aerosol emission airflow path 102 arranged to face the atomization core 20 and the air inlet of the aerosol emission airflow path 102 configured to be interconnected with the startup airflow path 101 may be the same air inlet. Specifically, the aerosol emission airflow path 102 is arranged to face the atomization core 20 in the first direction Y through the second air inlet 1021.

[0059] Due to this arrangement, the second air inlet 1021 can not only be used to allow the air in the startup airflow path 101 to flow into the aerosol emission airflow path 102 for inhalation and startup, but also be used to allow the aerosols at the atomization core 20 to flow into the aerosol emission airflow path 102, in this way, emission of the aerosols formed by heating and atomizing the atomization liquid at the atomization core 20 is realized. In this manner, in order to enable the aerosols at the atomization core 20 to smoothly flow through the second air inlet 1021 to the aerosol emission airflow path 102, so as to flow out through the second air outlet 1022 of the aerosol emission airflow path 102, the second air inlet 1021 is generally larger. Thus, the air in the startup airflow path 101 is also facilitated to flow into the aerosol emission airflow path 102 during the inhalation starting process, so as to achieve the inhalation startup effect.

[0060] In other embodiments, the aerosol emission airflow path 102 may be provided with a plurality of air inlets, an air inlet of the aerosol emission airflow path 102 arranged to face the atomization core 20, and an air inlet of the aerosol emission airflow path 102 configured to be interconnected with the startup airflow path 101 may be different air inlets. That is, the second air inlet 1021 is arranged at some of the air inlets of the aerosol emission airflow path 102, and the remaining air inlets of the aerosol emission airflow path 102 and the atomization core 20 are arranged to face each other in the first direction Y.

[0061] In some embodiments, with reference to FIGS. 2-4 and in combination with other drawings, FIG. 4 is a three-dimensional structural diagram of a housing 11 of a mouthpiece assembly 10 provided in some embodiments of the present invention. The startup airflow path 101 includes a first airflow path 1013. The mouthpiece assembly 10 includes the housing 11 and a mouthpiece 12.
