Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

The following disclosure provides many different embodiments, or examples, for implementing different features of the invention. To simplify the disclosure of the present invention, the components and arrangements of specific examples are described below. Of course, they are merely examples and are not intended to limit the present invention. Furthermore, the present invention may repeat reference numerals and/or letters in the various examples. This repetition is for the purpose of simplicity and clarity and does not in itself dictate a relationship between the various embodiments and/or configurations discussed. In addition, the present invention provides examples of various specific processes and materials, but one of ordinary skill in the art may recognize the applicability of other processes and/or the use of other materials.

The applicant finds that in the electronic atomization device in the related art, small liquid beads can be formed in the mist outlet channel due to condensation, oil frying, insufficient sealing or siphon and the like, the small liquid beads are silted up to the mist outlet channel under the action of liquid tension and cannot be discharged, and when a user sucks the electronic atomization device with great force, the small liquid beads can enter the mouth of the user from the mist outlet channel, or when the electronic atomization device is inverted instantly or is inverted and swung, the small liquid beads can be thrown out from the outlet of the mist outlet channel, so that a liquid leakage phenomenon is generated.

For example, taking an electronic atomization device as an electronic cigarette as an example, two main ways and reasons for generating smoke oil into the mouth are provided. On one hand, small liquid beads are formed in the air flue after the smoke is generated and cooled, the small liquid beads slide down and are deposited on the pipe orifice under the influence of gravity after being accumulated, the small liquid beads are deposited on the pipe orifice and cannot fall off under the action of liquid tension, and the small liquid beads are taken into the inlet or thrown out of a smoke bomb when being vigorously sucked or inverted, so that the liquid leakage phenomenon is generated. On the other hand, the leaked liquid generated by the insufficient sealing or the fried oil generated by the atomization of the smoke is remained in the atomization bin to form accumulated liquid, most of the leaked liquid can flow into the liquid absorption cotton of the base from the bottom of the silica gel of the heating wire, a small part of the leaked liquid can climb to the air passage under the holding of the negative pressure generated by the suction because of the siphon suction, and the fried oil is smaller than the aerosol droplets and rises along with the air flow, so that the leaked liquid suction can be caused.

In order to solve at least the above technical problems, the present application proposes a mist outlet housing 1, a nebulizer holder 2, a mist outlet assembly 100 and an electronic atomizing device 1000 for the electronic atomizing device 1000, so as to solve the problems of liquid leakage of the electronic atomizing device 1000 and inhalation of liquid droplets by a user to some extent. It should be noted that the specific type of the electronic atomization device 1000 according to the embodiment of the present invention is not limited, and may be, for example, an electronic cigarette, a medical atomizer 4, or other atomization products.

Next, referring to the drawings, a mist outlet housing 1 for an electronic atomizing device 1000 according to an embodiment of the present invention is described.

As shown in fig. 1, the mist discharge housing 1 includes: the mist outlet pipe 11 and the flow guiding structure 3, the flow guiding structure 3 is arranged on the mist outlet pipe 11 and is suitable for guiding the liquid drops accumulated at the air inlet end 111 of the mist outlet pipe 11 out of the mist outlet pipe 11 from the air inlet end 111. Therefore, small liquid beads deposited at the air inlet end 111 of the mist outlet pipe 11 can be discharged out of the mist outlet pipe 11 from the air inlet end 111 under the action of the drainage structure 3, so that the problem that the small liquid beads are sucked out or leaked out of the air outlet end 112 of the mist outlet pipe 11 can be avoided, and the liquid leakage problem of the electronic atomization device 1000 and the problem that a user sucks the small liquid beads in the mist outlet pipe 11 are improved to a certain extent.

It should be noted that "the flow guiding structure 3 is disposed on the mist outlet pipe 11 and is adapted to guide the liquid droplets accumulated at the air inlet end 111 of the mist outlet pipe 11 out of the mist outlet pipe 11 from the air inlet end 111" is understood as a broad sense, that is, the small liquid beads deposited at the air inlet end 111 of the mist outlet pipe 11 may not only be under the action of the flow guiding structure 3, but also be accompanied by the self-gravity action of the small liquid beads to be discharged from the air inlet end 111 to the outside of the mist outlet pipe 11. In addition, it can be understood that the above technical effects can be achieved when the drainage structure 3 has a guiding function, a tension breaking function, and the like, and thus the specific structure of the drainage structure 3 is not limited.

In some embodiments of the present invention, as shown in fig. 1, the mist outlet housing 1 further includes a housing body 10, a cavity is formed in the housing body 10, the mist outlet pipe 11 is disposed in the cavity, and the housing body 10, the mist outlet pipe 11 and the flow guiding structure 3 are an integrally formed part. Therefore, the independent assembly connection is not needed, the processing and the manufacturing are convenient, the structural reliability is high, the structural strength is good, and the shell body 10 can be used for protecting the mist outlet pipe 11. Of course, the invention is not limited thereto, and in other embodiments of the invention, the flow directing structure 3 and the mist outlet pipe 11 may also be a separate piece and be connected by fitting, such as snapping, screwing, bonding, welding, etc.

In some embodiments of the present invention, as shown in fig. 1, the flow guiding structure 3 is disposed near the air inlet end 111 of the mist outlet pipe 11, that is, the distance between the flow guiding structure 3 and the air outlet end 112 of the mist outlet pipe 11 is greater than the distance between the flow guiding structure 3 and the air inlet end 111 of the mist outlet pipe 11. Therefore, the distance between the drainage structure 3 and the liquid drops accumulated at the air inlet end 111 of the mist outlet pipe 11 can be shortened, so that the drainage structure 3 can better play the drainage role on the premise of smaller size, the processing can be simplified, and the structural complexity is reduced. Of course, the invention is not limited thereto, and the flow guiding structure 3 may also be arranged in the whole mist outlet pipe 11 and extend along the whole length direction of the mist outlet pipe 11, and so on, so that the flow guiding function may also be realized.

It should be noted that the specific structure of the drainage structure 3 according to the embodiment of the present invention is not limited, and the following description is given by way of example.

Example one

As shown in fig. 1 to 4, the flow guiding structure 3 includes a first protrusion 31, and at least a portion of the first protrusion 31 is located outside the mist outlet pipe 11 and is disposed on an end surface of the air inlet end 111 of the mist outlet pipe 11. That is, at least a portion of the first protrusion 31 is located outside the mist outlet pipe 11 and connected to an axial end surface of the air inlet end 111 of the mist outlet pipe 11, so that the structure of the mist outlet pipe 11 is not affected, and the processing is convenient. Therefore, since the portion of the end surface of the air inlet end 111 of the mist outlet pipe 11, which is not connected to the first protrusion 31 and is adjacent to the first protrusion 31, may form a space (for example, at the first interval S1 shown in fig. 1) with the side wall surface of the first protrusion 31, the tension of the liquid droplets accumulated at the air inlet end 111 of the mist outlet pipe 11 may be broken by the space, so that the liquid droplets accumulated at the air inlet end 111 of the mist outlet pipe 11 may be sucked into the space, and thus the liquid droplets flow out of the mist outlet pipe 11 from the air inlet end 111 of the mist outlet pipe 11, and a reliable and effective flow guiding function is achieved.

As shown in fig. 2, the first protrusions 31 are at least two and are arranged along the circumferential direction of the air inlet end 111, and a first interval S1 is formed between every two adjacent first protrusions 31. Therefore, the processing is convenient, and the first interval S1 is formed between the adjacent first protrusion 31 and the end surface of the air inlet end 111, so that the first interval S1 can better suck the liquid drops accumulated at the air inlet end 111 of the mist outlet pipe 11, so that the liquid drops can more effectively flow out of the mist outlet pipe 11 from the air inlet end 111 of the mist outlet pipe 11, and a reliable and effective drainage effect is achieved. It should be noted that the number of the first protrusions 31 is not limited, and may be set according to actual requirements, for example, two, three, four, five, and so on.

As shown in fig. 2, the circumferential dimension of the at least one first space S1 is greater than or equal to one-fourth of the circumferential dimension of the air inlet end 111 of the mist outlet pipe 11, for example, the circumferential dimension of the first space S1 may be set to be 0.25 times, 0.3 times, 0.35 times, 0.4 times, etc. of the circumferential dimension of the air inlet end 111 of the mist outlet pipe 11. Thereby, it is ensured that the size of the first space S1 is large enough to more reliably suck in the liquid droplets accumulated at the air inlet end 111 of the mist outlet pipe 11, so that the liquid droplets more effectively flow out of the mist outlet pipe 11 from the air inlet end 111 of the mist outlet pipe 11, and a reliable and effective flow guiding function is achieved. Of course, the invention is not limited thereto, and the specific size of the first space S1 may also be specifically set according to actual requirements, and is not limited herein.

It should be noted that the circumferential dimension of the first space S1 along the axial direction of the mist outlet pipe 11 may be set to be a constant form (i.e., a uniform cross-sectional structure), or a gradually changing form, or a form having several abrupt changes. Without limitation, in one specific example, the maximum circumferential dimension of the first space S1 may be equal to or greater than one-fourth of the circumferential dimension of the air inlet end 111 of the mist outlet pipe 11, thereby ensuring reliable and effective flow guiding.

As shown in fig. 2, the radially inner side surface of the first projection 31 is flush with the inner wall of the intake end 111 or projects inward (i.e., radially inward) beyond the inner wall of the intake end 111. It should be noted that "radial" described herein refers to the radial direction of the mist outlet pipe 11, and "circumferential" refers to the circumferential direction of the mist outlet pipe 11, and the mist outlet pipe 11 is not limited to a circular pipe, and may be a pipe with an approximately circular pipe or polygonal cross section, and so on. That is, the radially inner side surface of the first protrusion 31 may be flush with the inner wall of the air inlet 111 of the mist outlet pipe 11, and a portion of the first protrusion 31 may protrude inward in the radial direction of the mist outlet pipe 11 beyond the inner wall of the air inlet 111. Therefore, a more effective drainage effect can be realized. Of course, the present invention is not limited thereto, and in other embodiments of the present invention, the radially inner side of the first projection 31 may also be located radially outward of the inner wall of the air intake end 111.

It should be noted that the thickness of the first protrusion 31 in the radial direction of the mist outlet pipe 11 may gradually change, or suddenly change, or be constant along the axial direction of the mist outlet pipe 11; the thickness of the first protrusion 31 may be greater than, or less than, or equal to the wall thickness of the mist outlet pipe 11. These are not limitative. In a specific example, the thickness of the first protrusion 31 in the radial direction of the mist outlet pipe 11 is equal to the wall thickness of the mist outlet pipe 11, the radially outer side surface of the first protrusion 31 is flush with the outer wall of the air inlet end 111 of the mist outlet pipe 11, and the radially inner side surface of the first protrusion 31 is flush with the inner wall of the air inlet end 111 of the mist outlet pipe 11.

In an alternative example of the first embodiment, as shown in fig. 3 and 4, the inner wall of the first protrusion 31 may be a smooth surface, but is not limited thereto. In another alternative example of the first embodiment, as shown in fig. 5, the connection position of the first protrusion 31 and the end surface of the air inlet end 111 is formed with a drainage groove S2, i.e. at least a part of the drainage groove S2 is located at the connection position of the first protrusion 31 and the end surface of the air inlet end 111, and the rest of the drainage groove S2 may not be located at the connection position of the first protrusion 31 and the end surface of the air inlet end 111, for example, may be distributed at any position of the whole first protrusion 31. The drainage groove S2 penetrates through the radial inner side surface of the first protrusion 31, and the drainage groove S2 penetrates through at least one side of the first protrusion 31 in the circumferential direction of the mist outlet pipe 11, and/or penetrates through one end of the first protrusion 31, which is far away from the air outlet end 112 of the mist outlet pipe 11 in the axial direction of the mist outlet pipe 11. Therefore, the liquid drops accumulated at the air inlet end 111 of the mist outlet pipe 11 can be sucked into the flow guide groove S2, and then flow out of the mist outlet pipe 11 from the air inlet end 111 of the mist outlet pipe 11 along the flow guide groove S2, so that reliable and effective flow guide is achieved.

Example two

As shown in fig. 6, the flow guiding structure 3 comprises a second protrusion 32, and at least a part of the second protrusion 32 is disposed in the air inlet end 111 of the mist outlet pipe 11. That is, at least a portion of the second protrusion 32 is located inside the mist outlet pipe 11 and connected to the inner wall of the air inlet end 111 of the mist outlet pipe 11, so as to facilitate processing. Therefore, since the portion of the inner wall of the air inlet end 111 of the mist outlet pipe 11, which is not connected to the second protrusion 32 and is adjacent to the second protrusion 32, may form a space (for example, at the second space S3 described later) with the side wall surface of the second protrusion 32, the tension of the liquid droplets accumulated at the air inlet end 111 of the mist outlet pipe 11 may be broken by the space, so that the liquid droplets accumulated at the air inlet end 111 of the mist outlet pipe 11 may be sucked into the space, and thus the liquid droplets flow out of the mist outlet pipe 11 from the air inlet end 111 of the mist outlet pipe 11, thereby performing a reliable and effective flow guiding function.

As shown in fig. 6, the second protrusions 32 are at least two and are arranged along the circumferential direction of the air inlet end 111, and a second interval S3 is formed between every two adjacent second protrusions 32. Therefore, the processing is convenient, and the second space S3 is formed between the adjacent second protrusion 32 and the inner wall of the air inlet end 111, so that the second space S3 can better suck the liquid drops accumulated at the air inlet end 111 of the mist outlet pipe 11, so that the liquid drops can more effectively flow out of the mist outlet pipe 11 from the air inlet end 111 of the mist outlet pipe 11, and a reliable and effective drainage effect is achieved. It should be noted that the number of the second protrusions 32 is not limited, and may be set according to actual requirements, for example, two, three, four, five, and so on.

As shown in fig. 6, the circumferential dimension of the at least one second space S3 is greater than or equal to one-fourth of the circumferential dimension of the air inlet end 111, for example, the circumferential dimension of the second space S3 may be set to be 0.25 times, 0.3 times, 0.35 times, 0.4 times, etc. the circumferential dimension of the air inlet end 111 of the mist outlet pipe 11. Therefore, the size of the second space S3 can be ensured to be large enough to more reliably suck in the liquid droplets accumulated at the air inlet end 111 of the mist outlet pipe 11, so that the liquid droplets more effectively flow out of the mist outlet pipe 11 from the air inlet end 111 of the mist outlet pipe 11, and a reliable and effective flow guiding effect is achieved. Of course, the invention is not limited thereto, and the specific size of the second space S3 may also be specifically set according to the actual requirement, and is not limited herein.

It should be noted that the circumferential dimension of the second space S3 along the axial direction of the mist outlet pipe 11 may be set to be a constant form (i.e., a uniform cross-sectional structure), or a gradually changing form, or a form having several abrupt changes. Without limitation, in one specific example, the maximum circumferential dimension of the second space S3 may be set to be equal to or greater than one-fourth of the circumferential dimension of the air inlet end 111 of the mist outlet pipe 11, thereby ensuring reliable and effective flow guiding.

As shown in fig. 6, an end of the second protrusion 32 away from the air outlet end 112 of the mist outlet pipe 11 is flush with the end surface of the air inlet end 111, or exceeds a side of the end surface of the air inlet end 111 away from the air outlet end 112 of the mist outlet pipe 11. It should be noted that the "axial direction" described herein refers to the axial direction of the mist outlet pipe 11. That is, an end surface of the second protrusion 32, which is far away from the air outlet end 112 of the mist outlet pipe 11, may be located on the same plane as an end surface of the air inlet end 111 of the mist outlet pipe 11, and a portion of the second protrusion 32 may extend to beyond the end surface of the air inlet end 111 along the axial direction of the mist outlet pipe 11 to be located outside the mist outlet pipe 11. Therefore, a more effective drainage effect can be realized.

It should be noted that the radial thickness of the second protrusion 32 along the axial direction of the mist outlet pipe 11 may be set to be a constant form (i.e. an equal thickness structure), or a gradually changing form, or a form having several abrupt changes. Further, it should be noted that the radially inner side surface of the second projection 32 may be a smooth surface, or an uneven surface, such as a serrated surface, or the like.

In an alternative example of the second embodiment, as shown in fig. 6, a second gap S4 is formed between the at least one second protrusion 32 and the inner wall of the mist outlet pipe 11, and the second gap S4 penetrates through two ends of the second protrusion 32 in the axial direction of the mist outlet pipe 11, so that the liquid droplets accumulated at the air inlet end 111 of the mist outlet pipe 11 can be sucked into the second gap S4, and flow out of the mist outlet pipe 11 from the air inlet end 111 of the mist outlet pipe 11 along the second gap S4, thereby achieving a reliable and effective flow guiding function.

But is not limited thereto. In another alternative example of the second embodiment, the second gap S4 may not be provided between the second protrusion 32 and the inner wall of the mist outlet pipe 11, and in this case, the second protrusion 32 may have the second gap S4, and the second gap S4 penetrates through both ends of the second protrusion 32 in the axial direction of the mist outlet pipe 11. Alternatively, in other examples of the second embodiment, the second gap S4 may not be formed on the second protrusion 32 and between the second protrusion 32 and the inner wall of the mist outlet pipe 11. Thereby, the liquid droplets accumulated at the air inlet end 111 of the mist outlet pipe 11 can be sucked into the second gap S4, and then flow out of the mist outlet pipe 11 from the air inlet end 111 of the mist outlet pipe 11 along the second gap S4, thereby performing a reliable and effective flow guiding function.

EXAMPLE III

As shown in fig. 7, the flow guiding structure 3 includes a spiral structure 33 disposed on an inner wall of the air inlet 111, the spiral structure 33 extends to an end surface of the air inlet 111, or exceeds a side of the end surface of the air inlet 111 away from the air outlet 112 of the mist outlet pipe 11, wherein the spiral structure 33 is a spiral protrusion or a spiral groove, for example, when the spiral structure 33 is a spiral protrusion, the spiral protrusion may extend to the end surface of the air inlet 111, or exceeds a side of the end surface of the air inlet 111 away from the air outlet 112 of the mist outlet pipe 11, and when the spiral structure 33 is a spiral groove, the spiral groove may extend to the end surface of the air inlet 111. Therefore, not only is the processing convenient, but also the tension of the liquid drops accumulated at the air inlet end 111 of the mist outlet pipe 11 can be broken by the spiral structure 33, so that the liquid drops accumulated at the air inlet end 111 of the mist outlet pipe 11 can flow along the spiral structure 33, and then flow out of the mist outlet pipe 11 from the air inlet end 111 of the mist outlet pipe 11, and a reliable and effective drainage effect is achieved.

Next, referring to the drawings, a nebulizer holder for an electronic atomizing apparatus 1000 according to an embodiment of the present invention will be described 2。

As shown in fig. 8 to 12, the electronic atomizing apparatus 1000 includes the mist outlet pipe 11, and the atomizer support 2 includes: the support comprises a support body 20 and a drainage structure 3, wherein the support body 20 is provided with a mist outlet cavity 21 which is suitable for being inserted and communicated with the air inlet end 111 of the mist outlet pipe 11, and the drainage structure 3 is arranged on the support body 20 and is suitable for leading liquid drops accumulated at the air inlet end 111 of the mist outlet pipe 11 out of the mist outlet pipe 11 from the air inlet end 111. Therefore, the small liquid beads deposited at the air inlet end 111 of the mist outlet pipe 11 can be discharged from the air inlet end 111 to the outside of the mist outlet pipe 11, for example, into the mist outlet cavity 21, under the action of the flow guiding structure 3, so that the problem that the small liquid beads are sucked out or leaked from the air outlet end 112 of the mist outlet pipe 11 can be avoided, and the problem that the electronic atomization device 1000 leaks liquid and the problem that a user sucks the small liquid beads in the mist outlet pipe 11 can be improved to a certain extent.

It should be noted that "the drainage structure 3 is disposed on the stent body 20 and is adapted to lead the liquid droplets accumulated at the air inlet 111 of the mist outlet pipe 11 out of the mist outlet pipe 11 from the air inlet 111" is understood in a broad sense, that is, the small liquid beads deposited at the air inlet 111 of the mist outlet pipe 11 may not only be under the action of the drainage structure 3, but also be accompanied by the action of the gravity of the small liquid beads to be discharged from the air inlet 111 to the mist outlet chamber 21. In addition, it can be understood that the above technical effects can be achieved when the drainage structure 3 has a guiding function, a tension breaking function, and the like, and thus the specific structure of the drainage structure 3 is not limited.

As shown in fig. 8-12, at least part of the flow-directing structure 3 is located in the mist outlet chamber 21, so that the flow-directing structure 3 can be arranged close to the air inlet end 111 of the mist outlet pipe 11. That is, the distance between the flow guiding structure 3 and the air outlet end 112 of the mist outlet pipe 11 is greater than the distance between the flow guiding structure 3 and the air inlet end 111 of the mist outlet pipe 11. Therefore, the distance between the drainage structure 3 and the liquid drops accumulated at the air inlet end 111 of the mist outlet pipe 11 can be shortened, so that the drainage structure 3 can better play the drainage role on the premise of smaller size, the processing can be simplified, and the structural complexity is reduced.

In some embodiments of the invention, as shown in fig. 9, the drainage structure 3 is an integral part of the stent body 20. From this, need not independent assembly connection, convenient processing and manufacturing, structural reliability is high, and structural strength is good. Of course, the invention is not limited thereto, and in other embodiments of the invention, the drainage structure 3 and the stent body 20 may be formed as a single piece and connected by fitting, such as clamping, screwing, bonding, welding, and the like.

Example four

As shown in fig. 8 to 12, the drainage structure 3 is a third protrusion 34 provided on the mist outlet cavity 21, that is, the third protrusion 34 is provided on the inner wall of the mist outlet cavity 21, wherein the third protrusion 34 is adapted to be in abutting fit and/or clearance fit with the air inlet end 111 of the mist outlet pipe 11, that is, the third protrusion 34 may be in abutting fit with the air inlet end 111 of the mist outlet pipe 11; or may be a clearance fit; or may be a clearance fit or an abutting fit. Therefore, the third protrusion 34 is matched with the air inlet end 111, so that the liquid drops accumulated at the air inlet end 111 of the mist outlet pipe 11 can flow out of the mist outlet pipe 11 from the air inlet end 111 of the mist outlet pipe 11, and a reliable and effective drainage effect is achieved.

In some examples of the fourth embodiment, as shown in fig. 8 to 10, the third protrusion 34 is adapted to be located axially outside the end surface of the air inlet end 111 of the mist outlet pipe 11, that is, the third protrusion 34 does not protrude into the air inlet end 111 and is not inserted into the peripheral wall of the air inlet end 111. Thereby, the assembly of the mist outlet pipe 11 and the atomizer support 2 is facilitated. Moreover, the third protrusion 34 can be matched with the air inlet end 111 to enable the liquid drops accumulated at the air inlet end 111 of the mist outlet pipe 11 to flow out of the mist outlet pipe 11 from the air inlet end 111 of the mist outlet pipe 11, so that a reliable and effective drainage effect is achieved.

When the third protrusion 34 is located axially outside the end surface of the air inlet end 111 of the mist outlet pipe 11, in some specific examples, as shown in fig. 9, the third protrusion 34 is adapted to be in abutting fit with the end surface of the air inlet end 111 of the mist outlet pipe 11. For example, the third protrusion 34 may be in contact engagement with only the end surface of the air inlet end 111 of the mist outlet pipe 11, and may not have an engagement gap with the end surface of the air inlet end 111. For another example, a part of the third projection 34 may be in contact fit with the end surface of the air intake end 111, and another part may be in clearance fit with the end surface of the air intake end 111. Therefore, the tension of the liquid drops accumulated at the air inlet end 111 can be broken by utilizing the space around the abutting joint position and the clearance joint position to suck the liquid drops, so that the liquid drops accumulated at the air inlet end 111 of the mist outlet pipe 11 flow out of the mist outlet pipe 11 from the air inlet end 111 of the mist outlet pipe 11, and the reliable and effective drainage effect is achieved.

Alternatively, when the third protrusion 34 is located axially outside the end surface of the air inlet end 111 of the mist outlet pipe 11, in some specific examples, as shown in fig. 10, a third gap S6 is formed between at least a part of the third protrusion 34 and the end surface of the air inlet end 111, and the third gap S6 penetrates through a radially inner side surface of the third protrusion 34 and at least one side of the third protrusion 34 in the circumferential direction of the mist outlet pipe 11. Therefore, the liquid droplets accumulated at the air inlet end 111 of the mist outlet pipe 11 can be sucked into the third gap S6, and then flow out of the mist outlet pipe 11 from the air inlet end 111 of the mist outlet pipe 11 along the third gap S6, thereby performing a reliable and effective flow guiding function.

It is understood that, in order to form the third gap S6, when the third protrusion 34 is not in abutting engagement with the end surface of the air inlet end 111 of the mist outlet pipe 11, the relative positions of the mist outlet pipe 11 and the atomizer holder 2 may be defined, and when the third protrusion 34 is in abutting engagement with the end surface of the air inlet end 111 of the mist outlet pipe 11, the end surface of the third protrusion 34 on the side facing the mist outlet pipe 11 may be processed to be non-planar, for example, to extend from the middle to the two sides in the direction away from the mist outlet pipe 11, or the end surface of the air inlet end 111 of the mist outlet pipe 11 may be processed to be non-planar, and so on, so that both abutting engagement and gap engagement may be ensured.

In other examples, the third protrusion 34 may also be at least partially in clearance fit with the rest of the air inlet end 111, for example, the third protrusion 34 extends to beyond the end surface of the air inlet end 111 in the direction of the air outlet end 112 of the mist outlet pipe 11, in this case, the third protrusion 34 may be located in the pipe cavity of the mist outlet pipe 11, or may be located in the peripheral wall of the mist outlet pipe 11, for example, the peripheral wall surface of the air inlet end 111 has a groove 36, the third protrusion 34 is inserted into the groove 36 and is in clearance fit with the groove 36, in this case, the third protrusion 34 is the same as the fourth protrusion 37 in the sixth embodiment, and thus, the position of the clearance fit may also be used to break the tension of the liquid droplets accumulated at the air inlet end 111 to suck the liquid droplets, so that the liquid droplets accumulated at the air inlet end 111 of the mist outlet pipe 11 flow out of the mist outlet pipe 11 from the air inlet end 111 of the mist outlet pipe 11, and thus playing a reliable and effective drainage role.

As shown in fig. 11 and 12, the third protrusions 34 are at least two and are arranged along the circumferential direction of the air inlet end 111, and a third interval S5 is formed between every two adjacent third protrusions 34. Therefore, the processing is convenient, and the third space S5 is formed between the adjacent third protrusions 34, so that the third space S5 can better suck the liquid drops accumulated at the air inlet end 111 of the mist outlet pipe 11, and the liquid drops can more effectively flow out of the mist outlet pipe 11 from the air inlet end 111 of the mist outlet pipe 11, thereby performing a reliable and effective drainage function. It should be noted that the number of the third protrusions 34 is not limited, and can be set according to actual requirements, and for example, the number of the third protrusions may be two, three, four, five, and the like.

As shown in fig. 11, the circumferential dimension of the at least one third space S5 is equal to or greater than one-fourth the circumferential dimension of the intake end 111. For example, the circumferential dimension of the third space S5 may be set to be 0.25 times, 0.3 times, 0.35 times, 0.4 times, etc. the circumferential dimension of the inlet end 111 of the mist outlet pipe 11. Thereby, it is ensured that the size of the third space S5 is large enough to more reliably suck in the liquid droplets accumulated at the air inlet end 111 of the mist outlet pipe 11, so that the liquid droplets more effectively flow out of the mist outlet pipe 11 from the air inlet end 111 of the mist outlet pipe 11, and a reliable and effective flow guiding function is achieved. Of course, the present invention is not limited thereto, and the specific size of the third space S5 may also be specifically set according to actual requirements, and is not limited herein.

It should be noted that the circumferential dimension of the third space S5 along the axial direction of the mist outlet pipe 11 may be set to be a constant form (i.e., a uniform cross-sectional structure), or a gradually changing form, or a form having several abrupt changes. Without limitation, in one specific example, the maximum circumferential dimension of the third space S5 may be set to be equal to or greater than one-fourth of the circumferential dimension of the air inlet end 111 of the mist outlet pipe 11, thereby ensuring reliable and effective flow guiding.

As shown in fig. 8 and 9, the radially inner side surface of the third projection 34 is flush with the inner wall of the intake end 111 or projects inward (i.e., radially inward) beyond the inner wall of the intake end 111. It should be noted that the term "radial" as used herein refers to the radial direction of the mist outlet pipe 11. That is, the radially inner side surface of the third protrusion 34 may be flush with the inner wall of the air inlet end 111 of the mist outlet pipe 11, and a part of the third protrusion 34 may protrude inward beyond the inner wall of the air inlet end 111 in the radial direction of the mist outlet pipe 11. Therefore, a more effective drainage effect can be realized. Of course, the present invention is not limited thereto, and in other embodiments of the present invention, the radially inner side of the third projection 34 may also be located radially outward of the inner wall of the air intake end 111.

It should be noted that the thickness of the third protrusion 34 in the radial direction of the mist outlet pipe 11 may gradually change, or suddenly change, or be constant along the axial direction of the mist outlet pipe 11; the thickness of the third protrusion 34 may be greater than, or less than, or equal to the wall thickness of the mist outlet pipe 11. These are not limitative.

In a specific example, as shown in fig. 11 and 12, the bracket body 20 includes a flow guide baffle 23 located on a side of the mist outlet cavity 21 away from the mist outlet pipe 11, the flow guide baffle 23 has a first direction and a second direction perpendicular to each other, with reference to fig. 15, the atomizer 4 is located on a side of the flow guide baffle 23 away from the mist outlet pipe 11, the mist generated by the atomizer 4 enters the mist outlet cavity 21 over two sides of the flow guide baffle 23 in the first direction, then enters the mist outlet pipe 11 through the mist outlet cavity 21, and referring back to fig. 11 and 12, the bracket body 20 further includes two cavity side walls 24 located on two sides of the flow guide baffle 23 in the second direction, and each of the cavity side walls 24 is provided with a first third protrusion 34. Therefore, the processing is convenient, and the requirements of the actual structure characteristics of the product are met.

EXAMPLE five

As shown in fig. 13, the drainage structure 3 is a drainage needle 35 disposed on the stent body 20 and extending into the air inlet 111. Thereby, the tension that breaks the liquid droplets accumulated in the air inlet end 111 can be exerted, and the liquid droplets can be introduced into the mist outlet chamber 21.

As shown in fig. 13, in a specific example of the fifth embodiment, the stent body 20 includes a flow guide baffle 23 located on a side of the mist outlet cavity 21 away from the mist outlet pipe 11, and the drainage needle 35 is provided on the flow guide baffle 23. Therefore, on one hand, the drainage needle 35 is fixed, so that the drainage needle 35 can extend into the tube cavity of the mist outlet tube 11, on the other hand, the drainage needle 35 can absorb the heat radiation of the atomizer 4 and keep a larger temperature difference with the inside of the mist outlet tube 11, the tension sealing phenomenon of condensate in the air inlet end 111 is damaged, and the liquid drop tension of the air inlet end 111 is damaged and flows into the mist outlet cavity 21. It can be understood that the atomizer 4 is located on the side of the flow guide baffle 23 away from the mist outlet pipe 11, and the mist generated by the atomizer 4 enters the mist outlet cavity 21 through the two sides of the flow guide baffle 23 and then enters the mist outlet pipe 11 through the mist outlet cavity 21.

For example, in a specific example, the drainage needle 35 may be a metal member, such as a nail, and extends into the mist outlet pipe 11 by about 3mm to 4mm, and one end of the nail has a disc-shaped cup head and is located on the flow guide baffle 23, so as to absorb the heat radiation of the atomizer 4, such as a heating wire, so that the temperature of the nail is greatly different from the temperature in the mist outlet pipe 11, thereby breaking the tension seal of the condensate, and breaking the tension of the liquid drops at the air inlet 111 to flow into the mist outlet chamber 21.

Next, referring to the drawings, a mist generation assembly for an electronic atomizer 1000 according to an embodiment of the present invention will be described 100。

As shown in fig. 14-15, the mist outlet assembly 100 includes: the atomizer support 2 comprises a support body 20, the support body 20 is provided with a mist outlet cavity 21 which is suitable for being inserted and communicated with the air inlet end 111 of the mist outlet pipe 11, and the flow guide structure 3 is suitable for guiding liquid drops accumulated at the air inlet end 111 of the mist outlet pipe 11 out of the mist outlet pipe 11 from the air inlet end 111. Therefore, the small liquid beads deposited at the air inlet end 111 of the mist outlet pipe 11 can be discharged from the air inlet end 111 to the outside of the mist outlet pipe 11, for example, into the mist outlet cavity 21, under the action of the flow guiding structure 3, so that the problem that the small liquid beads are sucked out or leaked from the air outlet end 112 of the mist outlet pipe 11 can be avoided, and the problem that the electronic atomization device 1000 leaks liquid and the problem that a user sucks the small liquid beads in the mist outlet pipe 11 can be improved to a certain extent.

It should be noted that "the flow guiding structure 3 is adapted to guide the liquid droplets accumulated at the air inlet 111 of the mist outlet pipe 11 out of the mist outlet pipe 11 from the air inlet 111" is understood in a broad sense, that is, the small liquid droplets deposited at the air inlet 111 of the mist outlet pipe 11 may not only be under the action of the flow guiding structure 3, but also simultaneously accompany the action of the self-gravity of the small liquid droplets to be discharged from the air inlet 111 to the mist outlet chamber 21. In addition, it can be understood that the above technical effects can be achieved when the drainage structure 3 has a guiding function, a tension breaking function, and the like, and thus the specific structure of the drainage structure 3 is not limited.

In some embodiments, the flow directing structure 3 is disposed proximate to the air inlet end 111 of the mist outlet pipe 11. That is, the distance between the flow guiding structure 3 and the air outlet end 112 of the mist outlet pipe 11 is greater than the distance between the flow guiding structure 3 and the air inlet end 111 of the mist outlet pipe 11. Therefore, the distance between the drainage structure 3 and the liquid drops accumulated at the air inlet end 111 of the mist outlet pipe 11 can be shortened, so that the drainage structure 3 can better play the drainage role on the premise of smaller size, the processing can be simplified, and the structural complexity is reduced. Of course, the invention is not limited thereto, and the flow guiding structure 3 may also be arranged in the whole mist outlet pipe 11 and extend along the whole length direction of the mist outlet pipe 11, and so on, so that the flow guiding function may also be realized.

In some embodiments, the drainage structure 3 is provided on at least one of the mist outlet pipe 11 and the stent body 20. That is, the flow guide structure 3 may be provided only on the mist outlet pipe 11 (for example, the first to third embodiments); or may be provided only on the holder body 20 (for example, the fourth to fifth embodiments); a part of the mist outlet pipe 11 may be provided, and the rest may be provided on the holder body 20 (for example, in the sixth embodiment described below). Therefore, different actual requirements can be met. For example, when the flow directing structure 3 is provided only on the mist outlet pipe 11, an existing atomizer holder can be utilized. For another example, when the gold drainage hook is only provided on the stent body 20, the existing mist outlet housing can be utilized, so that the cost can be reduced to some extent. For another example, when a part of the drainage structure 3 is provided on the mist outlet pipe 11 and the rest is provided on the stent body 20, the droplet discharge effect can be improved.

In some embodiments, as shown in fig. 14 and 15, the mist outlet housing 1 further includes a housing body 10, the mist outlet pipe 11 is disposed in the housing body 10, the housing body 10 has a liquid storage cavity 12 outside the mist outlet pipe 11, the support body 20 has a liquid supply cavity 22 outside the mist outlet cavity 21, the liquid storage cavity 12 is communicated with the liquid supply cavity 22, and the mist outlet assembly 100 further includes an atomizer 4, and the atomizer 4 is communicated with the liquid supply cavity 22 and the mist outlet cavity 21, respectively. Thus, the liquid in the liquid storage chamber 12 can flow to the atomizer 4 through the liquid supply chamber 22 (for example, the hollow arrow in fig. 14 indicates the liquid flow direction) to be atomized, and the atomized mist can flow out into the mist outlet pipe 11 through the mist outlet chamber 21 and then be discharged out of the mist outlet housing 1 through the air outlet end 112 of the mist outlet pipe 11 (for example, the hollow arrow in fig. 15 indicates the mist flow direction).

In some specific examples, as shown in fig. 14 and 15, the atomizer 4 may include an atomizing chamber 41, a heating member 43, an air inlet passage 42, and other components, which are not described in detail herein. Furthermore, in some embodiments of the present invention, the mist outlet assembly 100 may further include a base 5, a sealing cover 7, and the like, the atomizer 4 is fixedly installed between the base 5 and the atomizer support 2, the sealing cover 7 is sealed at the matching position of the atomizer support 2 and the mist outlet housing 1 to ensure the reliability of the communication between the liquid storage chamber 12 and the liquid supply chamber 22 and the reliability of the communication between the mist outlet chamber 21 and the mist outlet pipe 11, and the base 5 may have an air inlet 51 communicated with the air inlet channel 42 of the atomizer 4 and an electrical connection member 6 electrically connected with the heating member 43, and the like, which is not limited herein.

It should be noted that the specific structure of the flow guiding structure 3 according to the embodiment of the present invention is not limited, and is described below by way of example.

EXAMPLE six

As shown in fig. 14 to 17, the drainage structure 3 includes a groove 36 and a fourth protrusion 37 axially inserted in the groove 36, with a fourth gap S7 between the groove 36 and the fourth protrusion 37; one of the groove 36 and the fourth protrusion 37 is provided in the mist outlet chamber 21, and the other is provided in the mist outlet pipe 11. For example, fig. 14 shows an example in which the groove 36 is provided on the mist outlet pipe 11, and the fourth protrusion 37 is provided on the inner wall of the mist outlet chamber 21, so that the fourth gap S7 can be used to break the tension of the liquid droplets accumulated at the air inlet end 111 of the mist outlet pipe 11, so as to suck the liquid droplets into the fourth gap S7, and then flow into the mist outlet chamber 21 along the fourth protrusion 37, so that the liquid droplets accumulated at the air inlet end 111 of the mist outlet pipe 11 flow out of the mist outlet pipe 11 from the air inlet end 111 of the mist outlet pipe 11, and thus reliable and effective drainage is achieved. On the contrary, when the fourth protrusion 37 is disposed on the mist outlet pipe 11, the groove 36 is disposed in the mist outlet chamber 21, and the description thereof is omitted.

As shown in fig. 15 to 17, the fourth projection 37 has a first portion 371 and a second portion 372 in the axial direction, the first portion 371 is inserted into the groove 36, and the size of the first portion 371 in the circumferential direction is smaller than that of the second portion 372 in the circumferential direction, so that a fourth gap S7 can be formed. Therefore, on the one hand, the liquid droplets accumulated at the air inlet end 111 of the mist outlet pipe 11 can be led out from the air inlet end 111 by the fourth gap S7 between the first part 371 and the groove 36, on the other hand, the liquid droplets led out from the air inlet end 111 can be more reliably led into the mist outlet chamber 21 by the second part 372, and the fourth protrusion 37 has high structural reliability and can stably guide the flow of the liquid droplets.

As shown in fig. 15, a fourth gap S7 is formed at least at one of between the bottom wall of the groove 36 and the axial end of the first part 371 remote from the second part 372, between the side wall of the groove 36 and the circumferential side wall of the first part 371, and between the axial end of the second part 372 close to the first part 371 and the end face of the intake end 111. Thus, the fourth gap S7 is conveniently formed, and a better tension breaking and drainage effect can be ensured.

It should be noted that the thickness of the first portion 371 in the radial direction of the mist outlet pipe 11 may be greater than, equal to, or less than the thickness of the second portion 372 in the radial direction of the mist outlet pipe 11, so as to meet different practical requirements. The sizes of the drainage grooves S2, the second gap S4, the third gap S6 and the fourth gap S7 are not limited, and may be, for example, 0.2mm to 0.3mm, so that the liquid drop tension can be reliably broken by the siphon action to extract the liquid drops at the air inlet end 111 out of the mist pipe 11 from the air inlet end 111.

As shown in fig. 14, the radially inner side surface of the fourth projection 37 is flush with the inner wall of the intake end 111 or projects inward (i.e., radially inward) beyond the inner wall of the intake end 111. It should be noted that the term "radial" as used herein refers to the radial direction of the mist outlet pipe 11. That is, the radially inner side surface of the fourth protrusion 37 may be flush with the inner wall of the air inlet end 111 of the mist outlet pipe 11, and a part of the fourth protrusion 37 may protrude inward beyond the inner wall of the air inlet end 111 in the radial direction of the mist outlet pipe 11. Therefore, a more effective drainage effect can be realized. Of course, the present invention is not limited thereto, and in other embodiments of the present invention, the radially inner side of the fourth protrusion 37 may also be located radially outward of the inner wall of the air intake end 111.

It should be noted that, as shown in fig. 16 and 17, the thickness of the fourth protrusion 37 in the radial direction of the mist outlet pipe 11 may gradually change, or suddenly change, or be constant along the axial direction of the mist outlet pipe 11; the thickness of the fourth protrusion 37 may be greater than, or less than, or equal to the wall thickness of the mist outlet pipe 11. These are not limitative.

Next, an electronic atomization apparatus 1000 according to an embodiment of the present invention is described with reference to the drawings.

As shown in fig. 18, the electronic atomizer 1000 may include: a body assembly 200 and a mist outlet assembly 100, wherein the mist outlet assembly 100 is mounted on the body assembly 200 and is the mist outlet assembly 100 for the electronic atomizer 1000 according to any of the present invention.

Therefore, the body assembly 200 can be used for arranging the control switch, the electric control device, the power supply device 91, the sensing device 92 and the like, so that the structural complexity of the fog outlet assembly 100 is reduced, and the body assembly 200 can be used for being held by a user conveniently. Moreover, in some embodiments, the body assembly 200 and the mist outlet assembly 100 can be detachably connected, so that the requirement that a user replaces the mist outlet assembly 100 and uses one body assembly 200 all the time is met, and the use cost of the user is reduced. Of course, the invention is not limited thereto, and in other embodiments, the body assembly 200 and the mist outlet assembly 100 may be fixedly connected.

Furthermore, it is understood that when the body assembly 200 includes the electric control device, the power supply device 91, and the like, and the body assembly 200 is assembled with the mist outlet assembly 100, the body assembly 200 can be electrically connected to the atomizer 4 in the mist outlet assembly 100, for example, through a contact, so as to supply power and control the atomizer 4 by the power supply device 91. In addition, in some specific examples, the body assembly 200 may include an appearance housing, that is, the body housing 8, and the body housing 8 may have an air inlet through hole 81 thereon, and after the body assembly 200 and the mist outlet assembly 100 are assembled in place, the air inlet through hole 81 may communicate with the air inlet 51 on the base 5 in the mist outlet assembly 100, so as to meet the air inlet requirement of the atomizer 4.
