Detailed Description

An embodiment of the present application provides a nebulizer, referring to fig. 1, 3, 7 and 9, comprising a housing assembly 10 and a atomizing assembly 30.

Wherein the housing assembly 10 comprises a bottom cover structure 11 having an air inlet 111a and a housing body 12 having an air outlet channel 12a, the bottom cover structure 11 and the housing body 12 defining an inner cavity 10a.

Specifically, the atomizer can be used for containing atomized liquid such as liquid medicine, tobacco tar and the like and atomizing the atomized liquid to generate aerosol for a user to inhale. The inner cavity 10a is defined by the bottom cover structure 11 and the housing body 12. The inlet port 111a is for inflow of a supply air flow, and the outlet passage 12a is for outflow of an air flow flowing in from the inlet port 111 a.

The atomizing subassembly 30 sets up in inner chamber 10a, and is located between air outlet channel 12a and bottom structure 11, atomizing subassembly 30 includes the atomizing seat 31 that has atomizing channel 30a, and set up the atomizing core 32 in atomizing channel 30a, the one end that atomizing seat 31 was equipped with the entry of atomizing channel 30a is connected with bottom structure 11, the one end that atomizing seat 31 was equipped with the export of atomizing channel 30a is connected with shell main part 12, form the air current route through atomizing channel 30a between air inlet 111a and the air outlet channel 12a.

Specifically, the atomizing assembly 30 is configured to atomize an atomized liquid to produce an aerosol. The specific structure thereof is not limited. The atomizing core 32 is used to heat the atomizing liquid to atomize the aerosol.

The air outlet channel 12a communicates with the atomizing channel 30a, and the air flow from the air inlet 111a flows into the atomizing channel 30a from the inlet of the atomizing channel 30a, flows through the air outlet channel 12a from the outlet of the atomizing channel 30a, and flows out.

The end of the atomizing base 31 provided with the inlet of the atomizing passage 30a is not spaced from the bottom cover structure 11, i.e. no space is formed between the end of the atomizing base 31 provided with the inlet of the atomizing passage 30a and the bottom cover structure 11.

During user inhalation, ambient air flows into the housing assembly 10 from the air inlet 111a, through the atomizing assembly 30 along the air flow path, and out the air outlet channel 12 a. The aerosol formed by the atomizing assembly 30 heating the atomized liquid can flow with the airflow for inhalation by the user.

When the atomizer is in a use state, aerosol is generated in the atomizing channel 30a, meanwhile, the outside air flow can also bring water vapor, and when the atomizer is switched to a non-use state (namely, the atomizer is not used for atomizing the atomized liquid to generate the aerosol), the aerosol and the water vapor can be condensed to form condensate. Therefore, if the atomizing channel 30a is spaced from the bottom cover structure 11, the aerosol and the vapor can easily diffuse into the inner cavity 10a to form condensate, so that the sealing requirement of the inner cavity 10a is greatly increased. In the present application, one end of the atomizing assembly 30 is connected to the housing main body 12, and the other end is connected to the bottom cover structure 11, and the atomizing passage 30a and the bottom cover structure 11 are not spaced apart, so that the sealing requirement of the inner cavity 10a can be reduced.

Another embodiment of the present application provides an electronic atomizing device comprising a power supply assembly and an atomizer according to any of the embodiments of the present application, the power supply assembly being electrically connected to the atomizing core 32.

Embodiments of the present application provide an atomizer and an electronic atomizing device, the atomizer comprising a housing assembly 10 and an atomizing assembly 30. The atomizing base 31 is connected to the bottom cover structure 11 such that an air flow path is formed between the air inlet 111a and the air outlet channel 12a through the atomizing channel 30 a. One end of the atomizing assembly 30 is connected to the bottom cover structure 11, but not spaced from the bottom cover structure 11, so that the aerosol in the atomizing channel 30a is not easy to diffuse into the inner cavity 10a to form condensate, thereby reducing the sealing requirement of the side wall of the inner cavity 10a for preventing condensate from leaking, and increasing the overall sealing stability of the atomizer.

In one embodiment, referring to fig. 2, 4, 8 and 10, the atomizing channel 30a includes an atomizing chamber 30aa communicating with the air outlet channel 12a, and a first channel 30ab communicating with the atomizing chamber 30aa, the atomizing core 32 is disposed in the atomizing chamber 30aa, and an end of the atomizing base 31 having the first channel 30ab extends toward a side close to the air inlet 111a to be connected with the bottom cover structure 11.

That is, the atomizing base 31 is formed with the first passage 30ab, i.e., a partial region of the atomizing base 31 extends toward the bottom cover structure 11 to be connected with the bottom cover structure 11, in addition to the atomizing chamber 30 aa. Specifically, the air flow flowing in from the air inlet 111a flows through the first passage 30ab and the atomizing chamber 30aa, and flows out from the air outlet passage 12 a. An atomizing core 32 of the atomizing assembly 30 is disposed within the atomizing chamber 30 aa. The first channel 30ab extends towards the side close to the air inlet 111a to facilitate connection of the atomizing base 31 with the bottom cover structure 11.

Of course, in some embodiments, the atomizing base 31 may have only the atomizing chamber 30aa, and the first channel is a part of the bottom cover structure 11, i.e., the end of the bottom cover structure 11 having the first channel extends toward the side near the atomizing base 31 to connect with the atomizing base 31 and to communicate the first channel with the atomizing chamber 30 aa.

In one embodiment, referring to fig. 1 to 6, the side wall of the first channel 30ab is connected to the side wall of the air inlet 111a, so that the atomizing channel 30a and the air outlet channel 12a are separated from the inner cavity 10a, respectively.

Specifically, the first channel 30ab is directly communicated with the air inlet 111a, and the air outlet channel 12a and the atomization channel 30a can be respectively plugged by a sealing structure (such as a sealing plug), so that condensate can be prevented from flowing into the inner cavity 10a, damage to a battery cell or the microphone 20 and the like arranged in the inner cavity 10a can be avoided, and meanwhile, liquid leakage can also be avoided.

It should be noted that only when the atomizer is in the non-use state, the air outlet channel 12a and the atomizing channel 30a are blocked by the installation seal structure, and no air flow occurs between the air inlet 111a and the air outlet channel 12 a. When the atomizer is in use, the sealing structure is not installed, so that air flows along the air flow path between the air inlet 111a and the air outlet channel 12 a.

The end of the atomizing base 31 facing away from the air outlet channel 12a is connected with the bottom cover structure 11, and the first channel 30ab extends to the air inlet 111a, so that the side walls of the two are connected, and therefore air flow can directly enter the atomizing channel 30a after flowing into the shell assembly 10 from the air inlet 111a, and then flows out of the air outlet channel 12a, and separation of the atomizing channel 30a from the inner cavity 10a can be achieved. This ensures that condensate does not flow into the inner chamber 10 a. On the one hand, the condensate can directly flow out from the air inlet 111a or the air outlet channel 12a through the atomization channel 30a, so that the condensate can be prevented from corroding the battery cell or the microphone 20, the short circuit of the air flow controller caused by the condensate can be avoided, and meanwhile, the tightness of the inner cavity 10a can be avoided, so that the risk of liquid leakage is reduced. On the other hand, the external air flow can be prevented from flowing through the inner cavity 10a, then being mixed with the air released by the battery cell arranged in the inner cavity 10a and flowing out of the air outlet channel 12a together, so that the air is sucked by a user. Thus, the air flow sucked by the user can be cleaner.

The manner in which the side wall of the first passage 30ab meets the side wall of the intake port 111a is not limited.

Illustratively, a sidewall of the air inlet 111a extends inwardly of the interior cavity 10a to form an air inlet passage into which an end of the sidewall of the first passage 30ab facing away from the atomizing chamber 30aa extends. Thus, the sealing structure can be plugged into the first channel 30ab directly from the air inlet 111a, so as to plug one end of the first channel 30ab, which is close to the air inlet 111 a.

It should be noted that the side wall of the air outlet channel 12a is also connected to the side wall of the atomizing channel 30a, so that the air outlet channel 12a is also separated from the inner cavity 10 a.

In addition, the manner in which the sealing structure closes the atomizing passage 30a varies depending on the specific structure of the atomizer.

For example, referring to fig. 2 and 4, a sealing structure may extend through the air inlet 111a and into the atomizing passage 30a to seal the atomizing passage 30 a.

As another example, referring to fig. 11 and 12, the bottom cover structure 11 has a mounting opening 111b, a side wall of the atomizing passage 30a near the side of the bottom cover structure 11 is connected to the side wall of the mounting opening 111b, and the side wall of the atomizing passage 30a has a first gas passing opening 30ac communicating with the gas inlet 111 a.

Specifically, the air inlet 111a is used for air flow into the atomizing passage 30a, and the mounting opening 111b is used for plugging the sealing structure into the atomizing passage 30 a. It will be appreciated that when the atomizing passage 30a is plugged by the sealing structure, the sealing structure may also extend to a position where the first gas passing opening 30ac is plugged, so that the gas inlet 111a is not communicated with the atomizing passage 30a, thereby further improving the sealing effect.

In addition, the sealing structure may be an accessory of the atomizer, such as a sealing plug detachably inserted into the air outlet passage 12a and the atomizing passage 30a, according to actual circumstances. When the atomizer is in a non-use state, sealing plugs are respectively plugged into the two ends of the air outlet channel 12a and the atomizing channel 30a, which are away from each other, so as to achieve a sealing effect, and when the atomizer is in a use state, the sealing plugs are detached from the atomizer.

Of course, the sealing structure may also be part of the atomizer structure, such as the seal 40 mounted on the housing assembly 10.

Illustratively, the atomizer further includes a seal 40, one end of the seal 40 extending into the atomizing passage and being rotatably coupled to the atomizing assembly, the seal 40 being rotatably switchable between blocking and venting the first gas passage 30 ac.

Specifically, the rotation of the sealing member 40 is performed by an external force, and the communication and blocking of the atomizing passage 30a can be performed according to the user's intention. Thus, the seal 40 does not need to be detached from the nebulization channel 30a when suction is performed through the nebulizer. Meanwhile, the sealing member 40 can act as a child lock, so that the child can be prevented from being opened by mistake, and the child can be prevented from being sucked by mistake.

In the position where the seal member 40 rotates to communicate with the first gas passing port 30ac, the atomizing passage 30a is in a conductive state, the gas inlet 111a communicates with the atomizing passage 30a through the first gas passing port 30ac, and the gas flow from the gas inlet 111a flows into the atomizing passage 30a from the first gas passing port 30ac and flows out from the gas outlet passage 12 a. When the sealing member 40 rotates to a position for sealing the first air passing port 30ac, the atomization channel 30a is in a sealing state, so that the air inlet 111a is not communicated with the atomization channel 30a, no air flow exists between the air inlet 111a and the atomization channel 30a, and condensate in the atomization channel 30a cannot flow out from one end close to the air inlet 111a, so that sealing of the atomization channel 30a is realized.

In one embodiment, referring to fig. 10, 12 and 13, the end of the sealing member 40 extending into the atomizing channel 30a includes a second channel 40a communicating with the atomizing channel 30a, the second channel 40a has a second air port 40aa corresponding to the first air port 30ac, the sealing member 40 communicates with the first air port 30ac by rotating to the second air port 40aa to communicate with the atomizing channel 30a, and the sealing member 40 bypasses the first air port 30ac by rotating to the second air port 40aa to block the atomizing channel 30a.

Specifically, the second passage 40a is located within the atomizing passage 30a and communicates with the atomizing passage 30 a. The first and second gas passing ports 30ac, 40aa are in correspondence, and the seal 40 may be rotated to place the second gas passing port 40aa in communication with the first gas passing port 30ac, or may be rotated to misalign the second gas passing port 40aa from the first gas passing port 30ac to place the second gas passing port 40aa out of communication with the first gas passing port 30 ac.

It will be appreciated that when the first gas pass port 30ac communicates with the second gas pass port 40aa, the gas flow from the gas inlet 111a may pass through the first gas pass port 30ac and the second gas pass port 40aa in sequence to flow through the second passage 40a to flow into the atomizing passage 30a. When the second air passing opening 40aa avoids the first air passing opening 30ac, the first air passing opening 30ac and the second air passing opening 40aa are not communicated with each other, and air flows into the atomizing passage 30a, so that the atomizing passage 30a can be plugged.

The shapes and the number of the first gas passing openings 30ac and the second gas passing openings 40aa are not limited, for example, the first gas passing openings 30ac and the second gas passing openings 40aa are in one-to-one correspondence, and are circular holes with the same external dimensions.

In addition, by adjusting the relative position between the first and second gas passing ports 30ac and 40aa, the communication area of the first and second gas passing ports 30ac and 40aa can also be adjusted to adjust the flow rate of the gas flow flowing along the gas flow path.

In one embodiment, the bottom cover structure 11 includes an end cover 111 having an air inlet 111a, and a microphone mounting 112 disposed on a side of the end cover 111 within the interior cavity 10 a.

Depending on the actual situation, the end of the atomizing base 31 facing away from the outlet channel 12a may be directly connected to the end cap 111, whereby the air flow path passes through the end cap 111, the atomizing assembly 30 and the housing body 12 in sequence.

In some embodiments, the end of the atomizing base 31 facing away from the air outlet channel 12a may also be connected to a microphone mounting base 112, where the microphone mounting base 112 has a third air port 112a and a mounting cavity, and the third air port 112a communicates with the air inlet 111a and the first air port 30ac, respectively, and is located in the air flow path, and the atomizer includes a microphone 20 disposed in the mounting cavity 112 b.

Specifically, the end of the atomizing assembly 30 facing away from the air outlet channel 12a is connected to the microphone mount 112, and the air flow passes through the air inlet 111a, the third air passing opening 112a, and the first air passing opening 30ac in this order, thereby flowing into the atomizing channel 30 a.

The first gas passing port 30ac and the third gas passing port 112a may be respectively in communication with the inner chamber 10 a. Thus, the air flow flowing through the third air passing port 112a can directly flow into the first air passing port 30ac after passing through the inner chamber 10 a.

It should be noted that, although the first air passing port 30ac and the third air passing port 112a are respectively communicated with the inner cavity 10a, that is, the air flow flowing in from the air inlet 111a will still pass through the inner cavity 10a during the suction process, no condensate will be generated during the suction process, so that no condensate leakage problem exists, and when the atomizer is in the non-use state, the air outlet channel 12a and the atomization channel 30a are blocked by the sealing structure, so that the condensate formed in the atomization channel 30a will not flow into the inner cavity 10a, and thus no sealing treatment is required for the inner cavity 10 a.

In addition, during aspiration, the lumen 10a is a relatively closed cavity, and even if the lumen 10a has an aperture, the air flow into the nebulization channel 30a is primarily from the air inlet 111a, thus eliminating the need to ensure that the lumen 10a is completely sealed.

Of course, other configurations of the microphone mounting 112 are possible, such as the microphone mounting 112 having a third channel that communicates between the first air port 30ac and the third air port 112a, and the air flowing through the third air port 112a flows into the first air port 30ac along the third channel.

In one embodiment, referring to fig. 11, 12 and 14, the microphone 20 has a normal pressure sensing surface and a negative pressure sensing surface, the normal pressure sensing surface is located on the airflow path between the air inlet 111a and the third air passing opening 112a, and the side wall of the mounting cavity 112b facing the negative pressure sensing surface has a sensing hole 112d communicating with the inner cavity 10 a.

Specifically, since the air flows through the third air passing port 112a, the inner cavity 10a and the first air passing port 30ac in sequence, a negative pressure is formed in the inner cavity 10a, and the normal pressure sensing surface of the microphone 20 is located on the air flow path, so that one side of the normal pressure sensing surface can maintain normal pressure, and thus a pressure difference can be formed at two sides of the microphone 20, and the microphone 20 can maintain normal operation.

It should be noted that referring to fig. 12, the microphone mounting base 112 further includes a wire hole 112c for passing the wire body in the housing assembly 10, and the air flow does not pass through the wire hole.
