Next, the structure of the atomizing device 100 will be described by taking the electronic cigarette in which the atomizing device 100 atomizes tobacco tar as an example. The following examples are given by way of illustration only and are not intended to limit the scope of the present application. It is understood that in other embodiments, the nebulizing device 100 may be other devices for nebulizing nebulized fluid such as medical fluid, and is not limited herein.

As shown in fig. 1 and 2, the atomizing device 100 includes a body 20 and a liquid storage assembly 40. The body 20 has the open closed chamber that holds, and stock solution subassembly 40 detachably installs in holding the intracavity, and stock solution subassembly 40 has the stock solution chamber that is used for storing the atomized liquid. The reservoir assembly 40 and the body 20 may be placed separately prior to use of the aerosolizing apparatus 100. When the atomization device 100 is used, a user can install the liquid storage assembly 40 in the accommodating cavity of the body 20, and the atomized liquid in the atomization assembly 21 can flow into the accommodating cavity to be atomized to form smoke for the user to suck.

So, be different from the prior art who injects the atomizing liquid in advance when the factory equipment or by the manual injection atomizing liquid of user when using, above-mentioned atomizing device 100's stock solution subassembly 40 can place independently of body 20, when using atomizing device 100, the user only need with whole stock solution subassembly 40 install to body 20 in the installation cavity can to avoided because of annotating liquid in advance in the equipment process or the manual various problems that annotate the liquid and cause when using. Moreover, after the atomized liquid in the liquid storage assembly 40 is used up, the user can take out the liquid storage assembly 40 for replacement without discarding the entire atomization device 100, thereby reducing the use cost of the atomization device 100.

As shown in fig. 3 to fig. 5, the liquid storage assembly 40 includes a liquid storage bottle 41 and a sealing unit 43, the atomized liquid can be stored in the liquid storage bottle 41, and the sealing unit 43 is used for sealing the liquid storage bottle 41 storing the atomized liquid.

Specifically, the liquid storage bottle body 41 is substantially a cylindrical structure, and includes a bottle bottom wall and a bottle side wall formed by extending from the edge of the bottle bottom wall toward the same direction, and the bottle side wall circumferentially surrounds the bottle bottom wall to form a liquid storage cavity with an open end together with the bottle bottom wall.

In particular, in some embodiments, the bottle body 41 is formed by a blow molding process, such that the bottom wall and the side wall of the bottle body are thinner, thereby providing a larger volume for accommodating more atomized liquid without changing the outer dimension of the bottle body 41. Preferably, the thickness of the bottom wall and the side wall of the bottle body of the liquid storage bottle body 41 is 1.04mm-0.15 mm. It can be understood that the shape, material and manufacturing process of the liquid storage bottle body 41 are not limited, and can be set as required to meet different requirements.

The sealing unit 43 is coupled to the open end of the reservoir chamber of the reservoir body 41 and includes a sealing member 432 and a sealing cover 434 circumferentially surrounding the edge of the sealing member 432. The sealing cover 434 is sleeved on one end of the side wall of the bottle body far away from the bottom wall of the bottle body, and the sealing member 432 is arranged corresponding to the opening end of the liquid storage cavity and is communicated with the liquid storage cavity. Preferably, the outer diameter of the sealing member 432 is smaller than the diameter of the open end of the reservoir, and the surface of the sealing member 432 on the side away from the reservoir is recessed inwardly to form a positioning groove.

Further, the sealing member 432 and the sealing cover 434 are integrally formed, and the thickness of the joint between the sealing cover 434 and the sealing member 432 is smaller than the thickness of the sealing cover 434 and the sealing member 432, so that the tensile strength of the joint between the sealing cover 434 and the sealing member 432 is smaller than the tensile strength of the sealing member 432 and the tensile strength of the sealing cover 434. In this manner, the joint between the sealing cover 434 and the sealing member 432 can be torn away from each other by an external force, thereby opening the reservoir chamber to release the atomized liquid.

In some embodiments, the sealing unit 20 is made of a material with a certain elasticity, such as silicon gel, so that the sealing unit 43 can be deformed in a restorable manner under the action of external force, and is firmly sleeved at the end of the side wall of the bottle body far away from the bottom wall of the bottle body, thereby preventing the atomized liquid in the liquid storage cavity from leaking. The outer side wall of the sealing cover 434 is circumferentially surrounded by at least one sealing rib, and the sealing rib is used for abutting against the wall of the installation cavity of the body 20, so that the atomized liquid in the body 20 is prevented from flowing out through the gap between the sealing cover 434 and the body 20. Specifically, in some embodiments, the outer sidewall of the sealing cover 434 is surrounded by two sealing ribs, which can perform a double sealing function.

Referring to fig. 3 to 5, the body 20 includes an atomizing element 21 and a nozzle element 23, the nozzle element 23 is detachably mounted to the atomizing element 21, the nozzle element 23 and the atomizing element 21 together define a mounting cavity for receiving the liquid storage element 40, the atomizing element 21 can heat the atomized liquid in the mounting cavity to generate smoke, and a user can inhale through the nozzle element 23.

Specifically, the atomizing assembly 21 includes an outer tube 211, a base unit 212, a heat generating unit 213 and an inner support 214, the base unit 212, the heat generating unit 213 and the inner support 214 are all coupled in the outer tube 211, the base unit 212 and the inner support 214 together form an air inlet channel, a flow guiding channel 2147a and an air outlet channel 2143b which are sequentially communicated, and the air flow in the external environment sequentially flows through the air inlet channel, the flow guiding channel 2147a and the air outlet channel 2143b and is then exhausted through the nozzle assembly 23.

In some embodiments, the outer tube 211 has a tubular structure with two open ends, and the central axis of the outer tube 211 extends in the first direction. The base unit 212 includes a mounting seat 2121 and a sealing seat 2123 that mate with each other. The mount 2121 is embedded in one end of the outer tube 211, and the mount 2121 has a mount inlet hole 2121a extending along a first direction. The sealing seat 2123 is connected to one side of the mounting seat 2121 in a matching manner, a heating element mounting groove having a bottom wall is formed at one end of the sealing seat 2123 away from the mounting seat 2121, and an air inlet hole 2123a of the sealing seat extending along the first direction is formed through the bottom wall of the heating element mounting groove. Thus, the seal holder air intake holes 2123a and the mount holder air intake holes 2121a communicate with each other to form an air intake passage through which an air current in the external environment can flow into the heating body mounting groove in a first direction.

The heat generating unit 213 includes a heat generating element 2132 and a conductive wire 2134. The heating element 2132 has a columnar structure, the heating element 2132 is supported on the bottom wall of the heating element mounting groove in a first direction, and the extending direction of the central axis of the heating element 2132 is a second direction. The conductive wire 2134 is wound around the outside of the heating element 2132 in the axial direction of the heating element 2132, and pins at both ends of the conductive wire 2134 are inserted into the seal holder 2123, respectively, to be connected to an external power supply structure. In this way, the air flow flowing into the heating element mounting groove from the air intake passage can flow through the heating element 2132, and the fumes generated by the heating element 2132 are carried away.

The inner bracket 214 is coupled to the sealing seat 2123 and includes an inner bracket body 2141, a mounting portion 2143, a breaking member 2145, and a flow guide member 2147. Specifically, the inner support body 2141 has a substantially hollow cylindrical structure extending along a first direction, one end of the inner support body 2141 is coupled to the seal mount 2121, and the nozzle assembly 23 is coupled to one end of the inner support body 2141 away from the seal mount 2123 to form a receiving cavity with the inner support body 2141. One end of the liquid storage assembly 40 is received in the end of the inner bracket main body 2141 away from the sealing seat 2123, and the other end of the liquid storage assembly 40 extends out of the inner bracket main body 2141 and is received in the suction nozzle assembly 23.

The mounting portion 2143 is disposed at one end of the inner support body 2141 close to the sealing seat 2123, two sides of the mounting portion 2143 in the second direction are spaced from a side wall of the inner support 214, the mounting portion 2143 and the side wall of the inner support 214 jointly define a liquid inlet space 2143a communicating with the sealing seat 2123, and the atomized liquid flowing from the liquid storage assembly 40 can flow into the sealing seat 2123 through the liquid inlet space 2143 a.

One end of the breaking member 2145 is connected to a side surface of the mounting portion 2143 away from the sealing seat 2123, and the other end of the breaking member 2145 extends in the first direction to protrude into the bottle body 41. Preferably, in an embodiment, the breaking element 2145 has a rod-shaped structure, a cross-section of the breaking element 2145 perpendicular to the first direction has a cross shape, and an outer diameter of the breaking element 2145 matches an inner diameter of the positioning groove of the sealing element 432.

Thus, after the liquid storage assembly 40 is received in the inner frame 214, the breaking element 2145 can be inserted into the positioning groove of the sealing element 432 and can push the sealing element 432 and the sealing cover 434 in the first direction to tear and separate from each other. After the sealing member 432 is separated from the sealing cover 434, the sealing member 432 is sleeved on the end of the breaking member 2145, so as to prevent the sealing member 432 from blocking the outlet end of the bottle body 41 and affecting the outflow of the atomized liquid.

Further, the mounting portion 2143 is further provided with an air outlet passage 2143b extending in a third direction perpendicular to the first and second directions. The flow guiding element 2147 is connected to the side of the mounting portion 2143 close to the sealing seat 2123, the flow guiding element 2147 covers at least a portion of the heating element 2132, the flow guiding element 2147 defines a flow guiding channel 2147a for guiding the flow of the air current, and the flow guiding channel 2147a has an air inlet end and an air outlet end opposite to each other in the first direction, wherein the air inlet end is communicated with the air inlet channel of the base unit 212, and the air outlet end is communicated with the air outlet channel 2143 b. Thus, the air flowing into the air inlet channel from the external environment flows into the air outlet channel 2143b through the flow guide channel 2147a, and then flows out from between the liquid storage assembly 40 and the inner support 214.

In some embodiments, the area of a cross section of the gas outlet end perpendicular to the first direction gradually decreases in a direction from the gas inlet end toward the gas outlet end. Thus, the flow guide channel 2147a functions to converge the air flow flowing in from the air inlet channel, and the air flow can flow along the outer circumferential surface of the heating element 2132 under the converging action of the flow guide channel 2147a, so that the atomization temperature of the heating element 2132 is more uniform.

Specifically, the flow guide part 2147 includes two flow guide portions, the two flow guide portions are oppositely disposed in the third direction, a flow guide channel 2147a is formed between the two flow guide portions, and the heating element 2132 is located between the two flow guide portions. One side of the portion of each flow guiding portion forming the air outlet end, which faces the flow guiding channel 2147a, is provided with a flow guiding surface 2147b, the flow guiding surfaces 2147b extend obliquely relative to the first direction, and the distance between the two flow guiding surfaces 2147b gradually decreases in the direction from the air inlet end to the air outlet end.

Thus, the airflow is divided into two paths after flowing out from the air inlet channel, and the two paths of airflow respectively flow along the outer circular surfaces of the two sides of the heating element 2132 in the third direction under the guiding action of the guiding surface 2147a until being converged at the outlet end of the guiding channel 2147a again, and finally flow out through the air outlet channel 2143 b. Therefore, the arrangement of the flow guide channel 2147a effectively solves the problem that no airflow flows through the side of the air inlet channel of the heating element 2132 far away from the sealing seat 2123 in the prior art, so that the atomization temperature of the heating element 2132 is more uniform, carbon deposition is not easily generated on the side of the heating element 2132 far away from the sealing seat 2123, and the atomized liquid is atomized to generate smoke with good taste.

Specifically, in some embodiments, an orthographic projection of each flow guide portion on a plane perpendicular to the first direction is in a fan ring shape, and the two flow guide portions together form a tubular structure to converge the airflow.

The suction nozzle assembly 23 is a hollow housing structure, the suction nozzle assembly 23 is detachably connected to one end of the atomizing assembly 21, and the suction nozzle assembly 23 and the atomizing assembly 21 together define a mounting cavity to accommodate the liquid storage assembly 40. Specifically, in some embodiments, the side wall of the inner bracket 214 is formed with a locking groove, and the inner side wall of the suction nozzle assembly 23 is protruded with a locking buckle 232 matching with the locking groove. Thus, one end of the suction nozzle assembly 23 is sleeved on one end of the inner support 214 away from the base unit 212 and inserted into the outer tube 211, and the buckle 232 is clamped in the clamping slot to fix the suction nozzle assembly 23 relative to the atomizing assembly 21.

In some embodiments, the body 20 further includes a heat insulation pipe 215, the heat insulation pipe 215 is a hollow tubular structure, and the heat insulation pipe 215 is sleeved outside the inner support 214 and is contained in the outer pipe 211 for preventing the heat of the smoke from being transferred outwards to cause the heat of the outer pipe 211 to be too high, which may cause a safety hazard.

In some embodiments, the body 20 further includes a sealing ring 216, the sealing ring 216 is in a ring structure, the sealing ring 216 is sleeved outside the inner support 214 and is received in the outer tube 211, and an end of the sealing ring 216 away from one end of the sealing seat 2123 abuts against an end surface of the nozzle assembly 23. In this way, condensate generated by the smoke can be effectively prevented from flowing out from the gap between the suction nozzle assembly 23 and the outer tube 211.

Referring to fig. 4, the atomized liquid flowing process of the atomization device 100 is as follows:

when the sealing member 432 is torn from the sealing cap 434 by the breaking member 2145, the atomized liquid in the liquid storage bottle body 41 enters the liquid inlet space 2143a through the gap between the sealing cap 434 and the breaking member 2145, and is then absorbed by the heating element 2132, and the heat generated by the heating element 2132 atomizes the atomized liquid into mist.

Referring to fig. 5, the airflow of the atomizing device 100 flows as follows:

the external air flow enters the flow guiding member 2147 of the inner support 214 through an air inlet channel formed by the mounting seat air inlet hole 2121a and the sealing seat air inlet hole 2123a, the air flow flows through the surface of the heating element 2132 under the flow guiding action of the flow guiding channel to take away the smoke generated by atomization, and the smoke flowing out of the flow guiding channel is discharged through the air outlet channel 2143b, the gap between the liquid storage bottle body 41 and the inner support 214 and the suction nozzle assembly 23 to be sucked by a user.

Above-mentioned atomizing device 100 has solved and has annotated atomizing device 100 in advance and has leaded to phenomenon such as oil leakage to appear in storage or transportation atomizing device 100 to cause atomizing device 100 to damage, when the suction take out the atomizing liquid easily in the mouth, the atomizing liquid is rotten easily and leads to the relatively poor problem of taste, has solved the user and has infused into the operation complicacy that the atomizing liquid exists by oneself, lead to the atomizing liquid to overflow easily, shortcomings such as weeping. Moreover, due to the arrangement of the flow guide channel 2147a, the airflow flowing out of the air inlet channel can flow along the outer circular surface of one side of the heating element 2132, which is deviated from the air inlet channel, so that the atomization temperature of the heating element 2132 is relatively uniform, carbon deposition is not easily generated on one side of the heating element 2132, and the atomized liquid has good taste. In addition, because the sealing unit 43 of the liquid storage assembly 40 is integrally formed, liquid leakage of the liquid storage assembly 40 in the transportation and storage processes is effectively avoided.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.
