When the user stops using the atomizer, the liquefied substance (including condensed aerosol and leaked aerosol generating substrate) falls along the atomization channel, and the trigger micropore is formed by the bottom cavity wall of the first cavity, so that the liquefied substance is basically collected in the bottom cavity wall of the first cavity, and cannot enter the second cavity through the trigger micropore, and therefore the phenomenon that the liquefied substance falls into the microphone to influence the microphone to work (such as causing the microphone to be self-started) is avoided, and the risk of damage to the microphone is reduced.

Description

Atomizer

Technical Field

The application relates to the technical field of atomizing devices, in particular to an atomizer.

Background

The atomizer is a device for atomizing an aerosol-generating substrate and forming minute substances which can be inhaled by a human body, has painless and rapid treatment effects particularly in the treatment of respiratory diseases, and is favored by a wide population of patients. The nebuliser typically comprises a storage bin storing an aerosol-generating substrate, a heating element for heating and nebulising the aerosol-generating substrate, and a microphone for sensing the user's suction, the microphone, when sensing the user's suction, controlling the power supply to deliver electricity to the heating element so as to nebulise the aerosol required by the user, the aerosol being delivered to the user via an airflow path within the nebuliser.

In a conventional atomizer, a microphone is mostly disposed below the airflow channel and is communicated with the airflow channel. After the user uses the atomizer, the aerosol remained in the airflow channel is easy to condense when meeting the inner wall of the cavity, and the condensed aerosol can fall down along the airflow channel and flow into the microphone below the airflow channel after being collected. Furthermore, when the aerosol-generating substrate in liquid form is stored in the atomizer, it is also possible that the stored aerosol-generating substrate in liquid form leaks from the storage bin to the microphone. Whether condensed aerosol or leaking aerosol generating substrate (collectively referred to herein as liquefied material), when it reaches the microphone can affect the microphone operation (e.g., cause the microphone to self-activate) and even damage the microphone.

Referring to fig. 1 and 2, an embodiment of the present application provides an atomizer 100, where the atomizer 100 has an atomization channel S1 and an air intake channel S2 and includes a transition chamber 20 and a microphone 40. The transition cavity 20 is divided into a first cavity Q1 and a second cavity Q2 which are independent, the first cavity Q1 is located at the lower end of the atomization channel S1 and is communicated with the atomization channel S1 and the air inlet channel S2, the first cavity Q1 and the second cavity Q2 are communicated through the trigger micropore K, and the trigger micropore K is higher than the bottom cavity wall of the first cavity Q1. The microphone 40 communicates with the second chamber Q2.

The atomizing passage S1 is a passage through which aerosol generated by atomization is discharged from the atomizer 100. The air intake passage S2 is a passage that allows external air to enter the atomizing passage S1 when the user pumps the aerosol. The transition chamber 20 is a solid structure having a certain space therein.

The transition cavity 20 is divided into a first cavity Q1 and a second cavity Q2, and the two cavities are communicated only through the trigger micropore K. The flow area of the trigger microwell K is typically set small and may be, but is not limited to, selected from 0 to 10mm ² Take on values between them (e.g. 0.05mm ² )。

The trigger microwell K is higher than the bottom wall of the first chamber Q1, which means that the lowest part of the trigger microwell K is higher than the bottom wall of the first chamber Q1. In the use state, the nebulization channel S1 is located above the transition chamber 20 in the direction of gravity, where "above" means that in the use state the trigger microwell K is located above the bottom chamber wall of the first chamber Q1 in the direction of gravity.

The communication between the microphone 40 and the second chamber Q2 means that the second chamber Q2 communicates with the space where the microphone 40 is located, and it is understood that the space where the microphone 40 is located communicates with the air intake passage S2 or directly communicates with the atmosphere.

When the user performs the sucking action on the atomizer 100, the air pressure in the first chamber Q1 is reduced, the air enters the first chamber Q1 through the air inlet channel S2, enters the second chamber Q2 through the space where the microphone 40 is located and then enters the first chamber Q1, and finally enters the atomizing channel S1 to bring the aerosol in the atomizing channel S1 out of the atomizer 100, so that the aerosol is used by the user.

When the user stops using the atomizer 100, the liquefied substance (including condensed aerosol and leaked aerosol-generating substrate) falls down along the atomizing channel S1, since the trigger micro-holes K are elevated by the bottom cavity wall of the first chamber Q1, the liquefied substance is substantially collected in the first chamber Q1 without entering the second chamber Q2 through the trigger micro-holes K, thereby preventing the liquefied substance from falling into the position of the microphone 40 to affect the operation of the microphone 40 (e.g., to cause the microphone 40 to self-start), and reducing the risk of damaging the microphone 40.

In some embodiments, referring to fig. 3, the bottom wall of the second chamber Q2 is higher than the bottom wall of the first chamber Q1. At this time, the second chamber Q2 is integrally higher than the bottom wall of the first chamber Q1, and the liquefied material deposited on the bottom wall of the first chamber Q1 needs to overflow the plane of the bottom wall of the second chamber Q2 before entering the microphone 40 through the trigger micro-hole K, so that the probability that the liquefied material reaches the microphone 40 is lower, and the risk that the microphone 40 is damaged is further reduced.

In some embodiments, referring to fig. 3 and in combination with fig. 5, a protrusion b2 is convexly disposed on the bottom wall of the second chamber Q2, and a trigger channel F that communicates with the microphone 40 and the second chamber Q2 is disposed in the protrusion b 2.

It is understood that the protrusion b2 is located in the second chamber Q2 and protrudes from the bottom wall of the second chamber Q2, and the triggering channel F penetrates the protrusion b2 and communicates with the space where the microphone 40 is located. It can be seen that the port of the trigger channel F located in the second chamber Q2 is higher than the bottom wall of the second chamber Q2, even if the liquefied material flows through the trigger micro-hole K to enter the second chamber Q2, the liquefied material is not easy to enter the microphone 40 through the trigger channel F under the barrier of the protrusion b2, so that the condensed aerosol is not easy to reach the microphone 40, and the risk of damage to the microphone 40 is further reduced.

In particular, referring to fig. 3, trigger microwell K is lower than the plane of the port of trigger channel F.

The port of the trigger channel F is located in the second chamber Q2, corresponding to the "gate" of fluid into the trigger channel F. When the trigger microwell K is located at the port of the trigger channel F, even if the liquefied material passes through the trigger microwell K and enters the second chamber Q2, the liquefied material needs to pass through the port of the trigger channel F to reach the microphone 40, and the content of the required liquefied material is greatly increased. Moreover, when it encounters the protrusion b2, the uncondensed aerosol is condensed by the outer wall of the protrusion b2 and deposited in the second chamber Q2 along the outer wall of the protrusion b 2. That is, the liquefied material/uncondensed aerosol is less likely to reach the microphone 40, further reducing the risk of damage to the microphone 40.

In some embodiments, referring to fig. 3 in combination with fig. 5, a sump C is configured in the bottom wall of the first chamber Q1.

The liquid collecting tank C may be concavely formed on the bottom wall of the first chamber Q1, or may be formed by providing a rail structure on the bottom wall of the first chamber Q1, which is not particularly limited. The liquid collecting tank C can be arranged opposite to the atomizing channel S1, namely, the liquid collecting tank C is positioned right below the atomizing channel S1, and the liquid collecting tank C can also be positioned obliquely below the atomizing channel S1.

The liquid collecting tank C improves the content of the liquefied substances collected by the first chamber Q1, can further reduce the probability that the liquefied substances reach the position of the microphone 40, and further reduces the risk of damaging the microphone 40.

In some embodiments, referring to fig. 3, and in combination with fig. 5, a raised surface T is provided on the bottom wall of the first chamber Q1 in a raised manner, and the air inlet channel S2 penetrates the raised surface T.

It will be appreciated that the elevation surface T is disposed in height adjacent to the nebulization channel S1 with respect to the rest of the bottom cavity wall of the first chamber Q1. The air inlet channel S2 penetrates through the elevation surface T, so that the liquefied substance deposited on the bottom cavity wall of the first chamber Q1 is not easy to flow out of the atomizer 100 from the air inlet channel S2, and the risk of liquid leakage can be reduced.

In some embodiments, referring to fig. 3 and referring to fig. 6, the transition cavity 20 has a third cavity Q3 communicating with the first cavity Q1 and a partition portion a1 disposed in the third cavity Q3, where the partition portion a1 encloses to form a second cavity Q2, the first cavity Q1 and the third cavity Q3 are sequentially arranged and communicated in the first direction X, and the trigger micro hole K is opened on a side of the partition portion a1 facing away from the first cavity Q1 in the first direction X.

The partition portion a1 may be integrally formed with the transition chamber 20, or may be provided separately (in this case, the two may be welded, thermally fused, fixedly connected, or the like), and is not particularly limited.

The trigger micropore K is formed in one side of the separation part a1, which is far away from the first chamber Q1, for the uncondensed aerosol in the atomization channel S1, the uncondensed aerosol enters the first chamber Q1, needs to pass through the third chamber Q3 and around the separation part a1 and then enters the second chamber Q2 through the trigger micropore K, and finally can reach the microphone 40 to be condensed so as to influence the microphone 40 to work, so that the flow path of the uncondensed aerosol reaching the microphone 40 is greatly prolonged, the condensation probability of the uncondensed aerosol before reaching the microphone 40 is increased, the probability of the uncondensed aerosol reaching the microphone 40 is reduced, and the damage risk of the microphone 40 is further reduced.

Further in the embodiment, referring to fig. 4, in the second direction Y intersecting the first direction X, the partition a1 is disposed with a gap between the side walls of the third chamber Q3.

In practical application, the upper end of the atomizing channel S1 in the height direction of the transition chamber 20 is the length direction and the width direction of the transition chamber 20 in the first direction X and the second direction Y, respectively. In the second direction Y, only a gap is left between the partition a1 and the side wall of the third chamber Q3, through which the flow speed of the liquefied substance can be slowed down, the probability that the liquefied substance reaches the microphone 40 is reduced, and the risk of damage to the microphone 40 is further reduced.

Specifically, part of the outer wall of the partition portion a1 is in interference connection with the side wall of the third chamber Q3, and a gap exists between part of the outer wall and the side wall of the third chamber Q3, which is not specifically limited. The gap size is not limited here, and may be set according to actual requirements.

In particular to the embodiment, referring to fig. 3 in combination with fig. 5 and 6, the atomizer 100 further includes an atomizing assembly 10, a circuit board 50, a support 20b, and a sealing member 20a, wherein the atomizing assembly 10 has an atomizing passage S1, the sealing member 20a is disposed at a lower end of the atomizing assembly 10, the circuit board 50 is mounted to the support 20b, and the support 20b is coupled to a lower end of the sealing member 20a and jointly forms the transition chamber 20. The microphone 40 is electrically connected to the circuit board 50.

The atomizing assembly 10 is the primary structure of the atomizer 100 for atomizing operation, and its specific structure depends on the type of atomizer 100. When the atomizer 100 is used for atomizing a liquid aerosol-generating substrate, it generally comprises a heating element 11, a liquid guiding element, etc., the heating element 11 is electrically connected to the circuit board 50, and may be a resistive heating element 11, an electromagnetic heating element 11, etc. The liquid guide piece can be liquid guide cotton, liquid guide ceramic and the like. The heating element 11 is located in the atomizing channel S1, and the liquid guiding element forms the atomizing channel S1. When the atomizer 100 is used for atomizing a solid aerosol-generating substrate, it may comprise a heating element 11 and a charging cartridge, the charging cartridge forming an atomizing channel S1, the heating element 11 being located in the atomizing channel S1. The specific configuration of the atomizing assembly 10 is not limited in the embodiments of the present application.

The circuit board 50 is electrically connected to the microphone 40, the heating element 11 and the power source. The specific configuration of the circuit board 50 is not limited herein, and reference may be made to conventional arrangements.

In this particular embodiment, the circuit board 50 is mounted below the support 20b, and the seal 20a is located above the support 20b and mates with the support 20b to form the transition cavity 20. The seal 20a is sealingly connected to the first chamber Q1 and the nebulization channel S1 within the transition chamber 20. The sealing member 20a may be a silicone member, a rubber member, or the like.

When the second chamber Q2 is surrounded by the partition portion a1, the partition portion a1 may be formed in a structure protruding on the inner wall of the seal 20a. The bottom wall of the transition chamber 20 is formed by the inner wall of the holder 20b facing the seal 20a, and the above-described structures constructed on the bottom wall may be directly provided on the holder 20 b.

At this time, the transition cavity 20 is formed by the mating of the bracket 20b and the sealing member 20a of the mounting circuit board 50, and the structure is simple and not redundant.

Further to the embodiment, referring to fig. 5, the bracket 20b has a support rib b1, and the support rib b1 is located in the first chamber Q1 and supports the seal 20a. The support rib b1 can improve the sealing degree between the sealing member 20a and the atomizing assembly 10, so as to ensure that no air leakage or liquid leakage exists between the atomizing channel S1 and the first chamber Q1. Meanwhile, the supporting rib b1 can also be used as a structure for constructing the liquid collecting tank C on the bottom cavity wall of the first cavity Q1, so that multiple purposes are achieved.

Wherein the support rib b1 may be, but is not limited to being, integrally formed with the bracket 20 b.

The leakage preventing portion a2 extends into the atomizing channel S1 and is in sealing connection (may be an interference fit) with the inner wall of the atomizing channel S1, so as to communicate the atomizing channel S1 with the first chamber Q1, and prevent the gaseous/liquid substance from leaking from the interface between the atomizing channel S1 and the first chamber Q1. Moreover, the leakage preventing portion a2 increases the fitting area of the seal 20a and the atomizing assembly 10, contributing to an improvement in the connection reliability of the seal 20a and the atomizing assembly 10.

The leakage preventing portion a2 may be, but is not limited to, an integrally formed part of the seal 20a.
