Fig. 1 shows a schematic diagram of an electronic atomization device 200 according to the present utility model, where the electronic atomization device 200 includes an atomizer 100 and a power supply mechanism 50 that can be electrically connected to the atomizer 100, and the power supply mechanism 50 may be fixedly connected to the atomizer 100 or detachably connected to the atomizer 100. The atomizer 100 is used to store and atomize a liquid substrate to generate an aerosol for inhalation by a user. The power supply mechanism 50 includes a controller (not shown) and a battery cell 51, the controller controlling the battery cell 51 to supply power to the atomizer 100.

Fig. 2 is a cross-sectional view of a nebulizer 100 according to one embodiment of the utility model. The atomizer 100 comprises a housing 10, a flexible support 20 and an atomizing element 30. The housing 10 houses the flexible support 20 and the atomizing element 30. The housing 10 further defines a central axis and the inner wall of the housing 10 cooperates with the flexible support 20 to form a reservoir 101 for storing a liquid matrix and supplying liquid to the atomizing element 30. The flexible support 20 has a liquid inlet 201, and the liquid inlet 201 is communicated with the liquid storage cavity 101. With further reference to fig. 11, the atomizing element 30 is used for atomizing the liquid matrix from the liquid storage chamber 101 to generate aerosol, and the atomizing element 30 includes a porous substrate 31 and a heating element 32 coupled to the porous substrate 31. Depending on the use, the porous substrate 31 is provided with the liquid suction surface 311 and the atomizing surface 312 facing each other in the lateral direction of the atomizer 100, i.e., in the direction perpendicular to the central axis. The liquid suction surface 311 is for receiving a liquid matrix, and the heating element 32 is coupled to the atomizing surface 312 for heating and atomizing the liquid matrix. The porous substrate 31 may be mounted on the flexible support 20 in an orientation such that the wicking surface 311 is parallel to the central axis, wherein the wicking surface 311 faces the inlet 201 and communicates with the reservoir 101 through the inlet 201 such that liquid matrix in the reservoir 101 flows through the inlet 201 to the wicking surface 311 and through the internal microporous structure of the porous substrate 31 to the atomizing surface 312. When the heating element 32 coupled to the atomizing face 312 completes the heating and atomizing of the liquid matrix, the generated aerosol is released from the atomizing face 312 and stored in the atomizing chamber 211 formed by the cooperation of the atomizing face 312 and the annular inner wall of the flexible support 20.

In some embodiments, the heating element 32 is made of stainless steel, nichrome, iron-chromium-aluminum alloy or metallic titanium, and is preferably formed on the atomization surface 312 in a manner of sintering after printing a proper pattern by mixing conductive raw material powder with a printing aid to form a paste, so that all or most of the surface of the heating element is tightly combined with the atomization surface 312, and the heating element has the effects of high atomization efficiency, less heat loss, dry burning prevention or great reduction of dry burning, and the like. Alternatively, the heating element 32 may take various forms, and the heating element 32 may be a sheet-shaped heating element combined with the atomizing surface 312 and formed with a specific pattern, or may be a plate-shaped heating element formed by a heating net or a heating wire spiral, a heating film, or other forms; for example, the particular pattern may be a serpentine shape.

In some embodiments, the flexible support 20 is made of a flexible, soft gel material, such as silicone, rubber, or thermoplastic elastomer (TPE), so the porous matrix 31 may be secured at the inlet 201 by an interference fit. It should be noted that, due to insufficient supporting force of the soft gel material, the sealing performance between the flexible support 20 and the porous substrate 31 is poor, and the liquid substrate may infiltrate into the atomizing chamber 211 through the gap between the porous substrate 31 and the flexible support 20 to cause leakage. Accordingly, to avoid leakage problems due to lack of rigid support, the atomizer 100 further comprises a first support portion 110, the first support portion 110 being positioned on a side of the flexible support 20 facing away from the porous substrate 31 for providing support in a direction towards the porous substrate 31 for pressing a portion of the flexible support 20 against the liquid-absorbing surface 311 of the porous substrate 31. Optionally, at least part of the first support 110 protrudes towards the atomizing element 30 with respect to the inner surface of the housing 10. The first support portion 110 is used as a hard member, and is matched with the soft flexible support 20 to realize a sealed hard support on the liquid suction surface 311 side of the porous substrate 31.

In some embodiments, a hollow tube 102 is disposed within the housing 10 for defining a mist guide passage (not shown). At least part of the flexible support 20 is located between the hollow tube 102 and the first support portion 110, and the first support portion 110 abuts against one side of the flexible support 20, which faces away from the hollow tube 102, to provide a hard support, so as to improve the sealing reliability between the hollow tube 102 and the flexible support 20, and prevent the liquid matrix in the liquid storage cavity 101 from penetrating into the atomization cavity 211 through a gap between the hollow tube 102 and the flexible support 20 to cause liquid leakage. As shown in fig. 5 and 6, the flexible support 20 has an air outlet 202 and defines the aerosolization chamber 211 therein. One end of the air outlet 202 is connected to the hollow tube 102 and the other end is connected to the atomizing chamber 211. Meanwhile, one end of the hollow tube 102, which is far away from the air outlet 202, is provided with a sucking port 103, and the sucking port 103 is communicated with the mist guide channel. The hollow tube 102 is used for guiding the aerosol stored in the atomizing cavity 211 out of the suction port 103 through the mist guiding channel for sucking by a user.

Referring to fig. 3, in the embodiment shown in fig. 2, the first supporting portion 110 is a part of the housing 10, protrudes from the inner wall of the housing 10 toward the central axis of the housing 10, and a part of the first supporting portion 110 is connected between the outer wall of the hollow tube 102 and the inner wall of the housing 10. It is noted that when the porous substrate 31 is in a dry state, a small amount of bubbles are generated when it absorbs the liquid substrate, and the bubbles are easily accumulated near the liquid inlet 201 to hinder normal liquid discharge in consideration of strong adsorptivity of the soft gel material. In order to make the porous substrate 31 absorb liquid smoothly, the first supporting portion 110 extends from the liquid inlet 201 into the liquid storage cavity 101. Alternatively, the first support portion 110 may correspond to the center position in the width direction of the liquid suction surface 311. Therefore, the first supporting portion 110 can guide the bubbles toward the liquid storage chamber 101 to the porous substrate 31, and the liquid substrate in the liquid storage chamber 101 can smoothly flow to the liquid inlet 201 through the guide of the first supporting portion 110.

Referring to fig. 7 and 8, in some embodiments, the first support portion 110 includes an annular portion 1101 sleeved on the outer wall of the hollow tube 102, and a support arm 1102 extending from the annular portion 1101 toward the liquid inlet 201, where the support arm 1102 presses a portion of the flexible support 20 against the liquid absorbing surface 311 of the porous substrate 31 to realize a sealed hard support. Wherein the annular portion 1101 is located in the liquid storage chamber 101, and the support arm 1102 corresponds to a center position in the width direction of the liquid suction surface 311. As described above, by providing the first support portion 110 extending from the liquid suction surface 311 to the liquid storage chamber 101, bubbles generated when the porous substrate 31 sucks liquid can be guided by the first support portion 110 in a direction away from the liquid inlet 201, and the first support portion 110 can drain the liquid substrate in the liquid storage chamber 101 to the liquid inlet 201.

Referring to fig. 9 and 10, in some embodiments, the first support 110 extends from the hollow tube 102 toward the flexible support 20, and a space is maintained between the first support 110 and an inner wall of the housing 10. The first support 110 may be positioned on a side of the flexible support 20 facing away from the porous matrix 31 of the atomizing element 30 for providing support in a direction towards the porous matrix 31 for pressing a portion of the flexible support 20 against the liquid absorbing surface 311 of the porous matrix 31.

In another embodiment, the first support 110 may be at least partially inserted into the flexible support 20 for pressing a portion of the flexible support 20 against the wicking surface 311 or the hollow tube 102 to promote seal reliability.

In some embodiments, as shown in fig. 4, a base 40 for supporting the flexible support 20 is also included within the atomizer 100. The base 40 is housed within the housing 10, is connected to the flexible support 20, and covers the open end of the housing 10. The base 40 is provided with an electrode jack 44, and a conductive electrode 60 (see fig. 8) of the atomizer 100 is inserted into the electrode jack 44, and the first supporting portion 110 extends substantially parallel to the conductive electrode 60. The conductive electrode 60 is supported on the other side of the porous substrate 31 facing away from the meniscus 311 so that the atomizing element 30 can receive electrical energy and heat and atomize the liquid matrix to produce an aerosol for use by a user. The base 40 includes a ventilation column 41, which ventilation column 41 is disposed substantially parallel to the liquid-absorbing surface 311 of the porous substrate 31, which may be fixedly disposed on the base 40 or as part of the base 40. Referring further to fig. 5 and 6, the flexible support 20 is provided with a ventilation socket 22 for receiving at least a portion of a ventilation column 41. By inserting the ventilation column 41 into the ventilation jack 22, a fixed connection of the flexible support 20 and the base 40 can be achieved. Wherein the ventilation jack 22 wraps the outer surface of the ventilation column 41 such that a ventilation channel (not shown) is defined between the outer surface of the ventilation column 41 and the inner surface of the ventilation jack 22. As the atomizing element 30 consumes the liquid matrix in the reservoir 101, the air pressure in the reservoir 101 is continuously reduced. The ventilation channel is used for providing air into the liquid storage cavity 101 to relieve or eliminate the air pressure difference between the inside and the outside of the liquid storage cavity 101, so as to avoid the air pressure difference from preventing the liquid substrate from entering the porous substrate 31 from the liquid absorbing surface 311, and simultaneously avoid the air in the atomization cavity 211 from reversely seeping into the liquid storage cavity 101 through the porous substrate 31, so that air-liquid contact occurs on the liquid absorbing surface 311 to form bubbles to block the liquid substrate from entering the porous substrate 31.

In an alternative example, the ventilation channel includes at least one air guide groove 410 located at the side of the ventilation column 41, and the air guide groove 410 and the inner surface of the ventilation jack 22 enclose the ventilation channel. In some examples, the air guide groove 410 extends on the outer side surface of the ventilation column 41 in a straight line or curved manner along the longitudinal direction of the ventilation column 41, so that the air guide groove 410 communicates with the liquid storage chamber 101 and the atomization chamber 211 to dynamically adjust the air pressure in the liquid storage chamber 101. Alternatively, the air guide groove 410 has a proper width or depth dimension to form a capillary effect, and the air exchanging column 41 is made of a hard material such as plastic to keep the size of the air inlet cross section of the air guide channel substantially stable. When the air pressure in the liquid storage cavity 101 is too low, under the driving of the internal and external pressure difference, the air in the atomization cavity 211 can enter the liquid storage cavity 101 through the ventilation channel to supplement air to the liquid storage cavity 101, so that the negative pressure in the liquid storage cavity 101 is reduced, and the phenomenon that the liquid is not smooth due to the too low air pressure in the liquid storage cavity 101 is avoided. The air guide groove 410 can prevent the liquid matrix in the liquid storage chamber 101 from leaking through the air guide groove 410 to some extent due to capillary action. Meanwhile, a small amount of liquid matrix from the liquid storage cavity 101 can be kept in the air guide groove 410, and when the air pressure in the liquid storage cavity 101 is too high due to temperature rise and the like, the liquid matrix can enter the ventilation channel to enable the liquid storage cavity 101 to be depressurized, so that liquid leakage of the liquid storage cavity 101 due to the fact that the air pressure in the liquid storage cavity 101 is too high is avoided.

In some embodiments, because the flexible support 20 is flexible, at least a portion of the flexible support 20 may provide a circumferential sealing connection between the housing 10 and the base 40 to prevent leakage of the liquid matrix within the liquid reservoir 101. As shown in fig. 6, the outer wall of the flexible support 20 is provided with a sealing rib 23 in a ring, and the sealing rib 23 is elastically pressed against the inner wall of the housing 10, so as to realize sealing fit between the flexible support 20 and the housing 10. In an alternative example, the outer wall of the flexible carrier 20 may also be annularly provided with a sealing surface 24, said sealing surface 24 being in sealing engagement with the inner wall of the housing 10.

In some embodiments, as shown in fig. 4, the base 40 includes a mounting portion 42 and an annular wall 43 extending from the mounting portion 42 toward the flexible support 20. Referring further to fig. 5, the flexible support 20 has an annular groove 25 formed on a side facing the base 40, and the mounting portion 42 is fixedly connected to the housing 10 by inserting an annular wall 43 into the annular groove 25. Alternatively, a portion of the annular wall 43 on the same side as the first support 110 is defined as a second support 420, the second support 420 being for at least partially supporting the flexible support 20. The first supporting portion 110 and the second supporting portion 420 are correspondingly located on the upper side and the lower side of the liquid inlet 201, that is, both are located on the side far away from the conductive electrode 60, and provide lateral support for the flexible support 20 in the direction perpendicular to the central axis, so that the first supporting portion 110 and the second supporting portion 420 are mutually matched on the upper side and the lower side of the liquid inlet 201, and therefore tightness between the flexible support 20 and the liquid absorbing surface 311 is ensured.

In some embodiments, referring further to fig. 4, the base 40 is further provided with an air inlet 45, the air inlet 45 is communicated with the atomizing chamber 211, and the air inlet 45 is coaxially disposed with the air outlet 202 of the flexible support 20. Wherein the projections of the atomizing element 30 and the air inlet 45 in a plane perpendicular to the central axis do not overlap each other, such that an air flow channel (not shown) between the air inlet 45 and the air outlet 202 is a straight channel, thereby avoiding that said air flow channel is blocked by the atomizing element 30, forming an air flow dead space region. Similarly, the atomizing face 312 of the atomizing element 30 is substantially parallel to the gas flow channel, thereby eliminating turning structures within the gas flow channel. Therefore, the airflow channel can smoothly penetrate through the atomization cavity 211, and simultaneously timely and fully guide out the aerosol generated by the atomization element 30, so that the formation of macromolecular particles in the aerosol is effectively reduced, the path of the aerosol reaching the suction port 103 is effectively shortened, the aerosol can enter the user port with better taste, and the user experience is obviously improved.

Unlike the prior art, the present application discloses an electronic atomizing device 200 and an atomizer 100 thereof. By limiting the adoption of the hard support in the atomizer 100, a part of the flexible support 20 made of soft rubber material is pressed on the liquid suction surface 311 of the porous matrix 31, so that the support and the flexible support 20 are matched on one side of the liquid suction surface 311 to form a sealed hard support, the sealing support performance of the liquid inlet 201 is improved, and the occurrence of oil leakage is prevented. Meanwhile, the first supporting portion 110 extends from the vicinity of the liquid inlet 201 into the liquid storage chamber 101, and can guide the liquid in the liquid storage chamber 101 and the bubbles generated by the liquid suction of the porous substrate 31.

It should be noted that the above description is only for illustrating the technical solution of the present utility model, and the present utility model may be implemented in many different forms, and is not limited to the embodiments described in the present specification, which are not provided as additional limitations on the present disclosure, for the purpose of making a thorough and complete understanding of the present disclosure. The above-described features are further combined with each other to form various embodiments not listed above, and are considered to be the scope of the present utility model described in the specification; further, it will be apparent to those skilled in the art that modifications and equivalents may be made to the technical solutions described in the above embodiments, and that all such modifications and equivalents do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
