The occurrences of this phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is understood explicitly and implicitly by those skilled in the art that the embodiments described herein can be combined with other embodiments.

The embodiment of the present application provides a cooling atomizer. Referring to FIGS. 1 to 17 , the cooling atomizer includes a housing 100 , an atomizing core 200 and a bracket 300 . The atomizing core 200 and the bracket 300 are arranged inside the housing 100, and the housing 100 is provided with a liquid storage chamber 101, an atomizing chamber 201 and an exhaust channel 102, at least a part of the atomizing core 200 is located in the atomizing chamber 201, And at least a part of the atomization core 200 is located in the liquid storage chamber 101, the atomization core 200 is used to atomize the aerosol generating substrate in the liquid storage chamber 101 to form an aerosol, and the corresponding area of the atomization core 200 constitutes the atomization chamber 201. The atomization chamber 201 communicates with the outside atmosphere.

The bracket 300 is provided with a first cooling channel 301 and a second cooling channel 302. The first cooling channel 301 is located downstream of the atomization chamber 201, and the aerosol flows through the first cooling channel 301 under the action of suction. The flow direction of the atomization chamber 201 is different, the second cooling channel 302 is located downstream of the first cooling channel 301, and the flow direction of the aerosol flowing through the second cooling channel 302 is different from that flowing through the first cooling channel 301 under the action of suction. The flow directions are different, and the exhaust channel 102 is located downstream of the second cooling channel 302 .

It can be understood that the working principle of the cooling atomizer is as follows:

The liquid storage chamber 101 is used for storing the aerosol generating substrate, and the aerosol generating substrate can be in contact with at least a part of the atomizing core 200 so as to enter into the atomizing core 200 . After the atomizing core 200 is powered on, the aerosol generating base material entering the atomizing core 200 is atomized, and the aerosol generating base material is atomized to form an aerosol in the atomizing chamber 201 .

The aerosol flows from the atomization chamber 201 through the first cooling channel 301 and the second cooling channel 302 in sequence, and then flows from the second cooling channel 302 to the exhaust channel 102 . Among them, when the aerosol enters the first cooling channel 301 from the atomization chamber 201, it will change direction for the first time, and when it enters the second cooling channel 302 from the first cooling channel 301, it will change direction for the second time, so that the aerosol During the process of flowing from the atomization chamber 201 to the exhaust channel 102 , the air path is tortuous, which increases the distance of the aerosol flowing from the atomization chamber 201 to the exhaust channel 102 . Moreover, since the first cooling channel and the second cooling channel 302 are arranged on the support 300, the aerosol is fully in contact with the support 300 when flowing through the first cooling channel 301 and the second cooling channel 302, greatly increasing the contact between the aerosol and the second cooling channel 302. The contact area of the bracket 300 enables the aerosol to have a sufficient cooling stroke. After the aerosol is fully cooled, it is finally discharged through the exhaust channel 102 for consumption by the user.

Compared with the prior art, the cooling atomizer has at least the following technical effects:

In this application, the first cooling channel 301 and the second cooling channel 302 are set on the bracket 300, and the flow direction of the aerosol in the first cooling channel 301 is different from that in the atomization chamber 201, and the aerosol flows in the second cooling channel 301. The flow direction in the cooling channel 302 is different from the flow direction in the atomization chamber 201, so that the aerosol changes direction at least twice during the process of entering the exhaust channel 102 from the atomization chamber 201 (as shown in Figure 8), and then The stroke of the aerosol flowing from the atomizing chamber 201 to the exhaust channel 102 is increased, and the contact area and contact time between the aerosol and the bracket 300 are also increased, so that when the atomizing core 200 is arranged parallel to the length direction of the exhaust channel 102 , the aerosol can also have a sufficient cooling stroke, and the aerosol can be sufficiently cooled, thereby reducing the temperature of the aerosol when it is discharged. The temperature reduction of the aerosol can prevent the user from feeling hot when inhaling, and on the other hand, when the aerosol discharge temperature is low, it can fully reflect the flavor of the aerosol-generating substrate and improve the user's inhalation taste. In this application, on the basis of not increasing the length of the housing 100, the atomizing core 200 is arranged parallel to the length direction of the exhaust channel 102, and it can also take into account that the aerosol has a sufficient cooling distance, so that the internal structure of the atomizer is more compact. The layout is reasonable, which is conducive to the miniaturization of the atomizer.

It should be noted that the first cooling channel 301 described in this application is located downstream of the atomization chamber 201, which means that when the user inhales the aerosol, a suction is applied to the exhaust channel, and the aerosol is discharged from the atomization chamber 201 under the action of suction Flow to the first cooling channel 301. The second cooling channel 302 described in this application is located downstream of the first cooling channel 301 , which means that the aerosol flows from the first cooling channel 301 to the second cooling channel 302 under the action of suction. The exhaust channel 102 described in this application is located downstream of the second cooling channel 302 , and the aerosol flows from the second cooling channel 302 to the exhaust channel 102 under the action of suction.

In this embodiment, the atomizing core 200 is connected to the side wall of the liquid storage chamber 101, and at least a part of the atomizing core 200 is located in the liquid storage chamber 101, and is used for contacting the aerosol in the liquid storage chamber 101 with the substrate. .

Specifically, in order to save space, the atomizing core 200 can be arranged such that the longest side of the atomizing core 200 is placed parallel to the extending direction of the exhaust channel 102, so as to reduce the space occupied by the atomizing core 200 in the atomizer.

In this embodiment, the first cooling channel 301 and the second cooling channel 302 are specifically enclosed by the bracket 300 and the casing 100 .

It can be understood that, as shown in FIG. 12 to FIG. 13 , the present application forms the first cooling channel 301 and the second cooling channel 302 by enclosing the bracket 300 with the housing 100 , so that the atomizer is placed horizontally, It can also maintain a tortuous aerosol circulation stroke and maintain a cooling effect.

Certainly, in some other implementation manners, the first cooling channel 301 and the second cooling channel 302 may also be composed of the bracket 300 only.

In this embodiment, the space between the atomizing core 200 and the bracket 300 constitutes the atomization chamber 201, and the bracket 300 is provided with a liquid accumulation tank 303, and the fluid accumulation tank 303 is arranged on the side of the bracket 300 facing away from the atomization chamber 201. The liquid accumulation tank 303 is surrounded by the housing 100 to form a liquid accumulation cavity, which communicates with the second cooling channel 302, and the liquid accumulation cavity is used to collect condensate formed during at least a part of the aerosol circulation.

Specifically, referring to Fig. 2 to Fig. 9, the atomizing core 200 is vertically arranged on the side of the support 300, the aerosol flows in the vertical direction in the atomizing chamber 201 under the action of suction, and the support 300 is far away from the atomizing chamber 201 One side cooperates with the housing 100 to form a liquid accumulation cavity, which is used to collect condensate formed during the circulation of the aerosol in the first cooling channel 301 , the second cooling channel 302 and the exhaust channel 102 .

Under the action of suction, the aerosol flows from the atomization chamber 201 into the first cooling channel 301, then from the first cooling channel 301 into the second cooling channel 302, and finally from the second cooling channel 302 into the exhaust channel 102. This process is Aerosol circulation process. The condensate formed during the circulation of the aerosol in the first cooling channel 301, the second cooling channel 302 and the exhaust channel 102 can flow into the liquid accumulation cavity. Since the temperature of the condensate is relatively low, when the condensate is stored in the accumulation When it is in the liquid cavity, it will absorb the heat on the bracket 300 , thereby reducing the temperature of the bracket 300 . Since the atomization chamber 201, the first cooling channel 301 and the second cooling channel 302 are all composed of the support 300, when the condensate absorbs the heat of the support 300, the temperature of the support 300 drops, and when the aerosol circulates in the tortuous cooling path, Constantly contacting the support 300, the support 300 can continuously absorb the heat of the aerosol, thereby achieving double cooling of the aerosol.

In this embodiment, the second cooling channel 302 and the exhaust channel 102 are arranged in a dislocation manner. Specifically, dislocation of the second cooling channel 302 and the exhaust channel 102 is formed, so that the aerosol needs to change direction for the third time from the second cooling channel 302 to enter the exhaust channel 102, thereby further increasing the aerosol entering from the exhaust channel 102. The journey from the atomization chamber 201 to the exhaust channel 102 prolongs the cooling process of the aerosol without increasing the length of the bracket 300 or the exhaust channel 102 , thereby improving the cooling effect. In addition, the second cooling channel 302 and the exhaust channel 102 arranged in a misplaced position will impact the exhaust channel 102 when the aerosol enters the exhaust channel 102 from the second cooling channel 302 after being subjected to the suction force, which is beneficial to the aerosol The entrained condensate is adsorbed on the side wall of the exhaust channel 102, so that the condensate slides down the side wall of the exhaust channel 102 into the second cooling channel 302, and then enters the liquid accumulation tank 303, which is conducive to condensation Liquid collection.

In this embodiment, the top of the bracket 300 is provided with a liquid guide surface 3041, the liquid guide surface 3041 is a slope, the liquid guide surface 3041 is used to guide the condensate to flow into the second cooling channel 302, and the liquid storage chamber 101 is located at the bottom of the second cooling channel 302 below.

Further, in this embodiment, the liquid guiding surface 3041 is set facing the exhaust channel 102 . When the aerosol flows through the exhaust channel 102, condensate will be formed on the side wall of the air flow channel after contacting the side wall of the air flow channel, and the condensate will slide down to the liquid guide surface 3041 along the side wall of the air flow channel, because the liquid guide surface 3041 It is an inclined surface, and under the guidance of the liquid guide surface 3041 , the condensate will flow into the second cooling channel 302 and then flow into the liquid collection cavity below the second cooling channel 302 . Since the length direction of the second cooling channel 302 is different from that of the first cooling channel 301, and the liquid accumulation chamber is below the second cooling channel 302, after the condensate flows into the second cooling channel 302, it will first flow into the into the effusion cavity.

Referring to Fig. 2 to Fig. 10, Fig. 14 to Fig. 16, in this embodiment, a liquid guiding groove 304 is formed on the top of the bracket 300, and the bottom end surface of the liquid guiding groove 304 is a liquid guiding surface 3041, wherein the liquid guiding surface 3041 is close to the The height of one side of the second cooling channel 302 is lower than the height of the side of the liquid guiding surface 3041 away from the second cooling channel 302, and the liquid guiding groove 304 can surround the condensate to prevent condensation The liquid flows out from the other sides of the liquid guiding surface 3041 , and the liquid guiding surface 3041 can guide the condensed liquid to flow into the second cooling channel 302 to prevent the condensed liquid from accumulating in the liquid guiding groove 304 .

Certainly, in some other embodiments, the liquid guiding surface 3041 may also be a funnel-shaped inclined surface, or may be formed by splicing a plurality of inclined surfaces, so as to collect the condensate and then flow into the second cooling channel 302 .

Of course, in some other embodiments, the liquid guide groove 304 can also be set as an annular groove, and the annular groove is arranged facing the side wall of the exhaust passage 102, so as to accept the condensate that slides down from the side wall of the exhaust passage 102, The liquid guiding surface 3041 can be set as an annular slide slope, and the condensate can slide down along the slide slope toward the second cooling channel 302 .

In this embodiment, there are at least two liquid accumulation grooves 303 , and the liquid accumulation grooves 303 are distributed on the bracket 300 along the flow direction of the aerosol flowing through the atomization chamber 201 under the action of suction. Specifically, in this embodiment, when the airflow flows vertically in the atomizing chamber 201 , the plurality of liquid accumulation grooves 303 are also distributed vertically. The multiple liquid accumulation grooves 303 distributed vertically can collect more condensate and absorb more heat from the bracket 300 , so that the aerosol in the atomization chamber 201 can contact the bracket 300 to start to cool down. In some implementations, a plurality of liquid accumulation tanks 303 may communicate with each other.

In this embodiment, among the plurality of liquid accumulation grooves 303, the height of the bottom surface of the lowest liquid accumulation groove 303 is higher than the height of the bottom surface of the atomizing core 200, and lower than the height of the center of the atomizing core 200, so that The plurality of liquid accumulation grooves 303 correspond to at least half of the area of the atomizing core 200 , and the condensate in the liquid accumulation grooves 303 can cool down the position on the bracket 300 corresponding to at least the upper half area of the atomizing core 200 .

Referring to Figures 5 to 16, in this embodiment, there are two first cooling channels 301, and the two first cooling channels 301 are respectively located on both sides of the bracket 300, and the aerosol enters the two channels in the atomizing chamber 201 respectively. In the first cooling channel 301 , the aerosol converges from the first cooling channel 301 on both sides to the second cooling channel 302 and then flows to the exhaust channel 102 . Setting two first cooling channels 301 can increase the contact area between the aerosol and the support 300 , and the support 300 can contact the aerosol in all directions, so as to realize efficient cooling of the aerosol.

2 to 17, in this embodiment, the cooling atomizer also includes a liquid absorbing part 400, which is located in the housing 100, and the liquid absorbing part 400 is arranged below the atomization chamber 201, and the liquid absorbing part 400 is used for To absorb the condensate entering the atomizing chamber 201. Specifically, when the liquid accumulation chamber is filled with condensate, the condensate will flow into the atomization chamber 201 along the first cooling channel 301, and after entering the atomization chamber 201, part of the condensate will be atomized for the second time, and the other part It will drop onto the liquid absorbing part 400 in the atomizing chamber 201 , and the liquid absorbing part 400 is used to lock the condensate that drops below the atomizing chamber 201 to prevent the condensate from leaking out of the atomizer.

In this embodiment, under the action of suction, the flow direction of the aerosol flowing through the first cooling channel 301 is perpendicular to the flow direction of the aerosol flowing through the atomization chamber 201 . Under the action of suction, the flow direction of the aerosol flowing through the second cooling channel 302 is perpendicular to the flow direction of the aerosol flowing through the first cooling channel 301 . Specifically, the length direction of the first cooling channel 301 is perpendicular to the length direction of the atomization chamber 201, and the length direction of the second cooling channel 302 is perpendicular to the length direction of the first cooling channel 301, which makes the circulation process of the aerosol more tortuous and makes the The aerosol can get the maximum cooling stroke in a limited space and improve the cooling effect.

In this embodiment, the bracket 300 is provided with a transitional arc surface at the corner of the first cooling channel 301 and the second cooling channel 302, so that the aerosol can be cooled from the first cooling channel while prolonging the cooling process of the aerosol. The flow from the channel 301 to the second cooling channel 302 is smoother. Of course, in some implementations, the bracket 300 may also be provided with a transitional arc surface at the corner of the atomization chamber 201 and the first cooling channel 301 .

In this embodiment, the casing 100 includes an upper cover 110 and a first sealing member 120 . The upper cover 110 is mated with the first sealing member 120 to form the liquid storage chamber 101. The atomizing core 200 is embedded in the first sealing member 120. One side of the atomizing core 200 is located in the liquid storage chamber 101, and the other side is located in the atomizing chamber. chamber 201. The bracket 300 is surrounded by the first sealing member 120 to form a first cooling channel 301 and a second cooling channel 302 , and a part of the bracket 300 is attached to the first sealing member 120 .

The atomizing core 200 is embedded in the first sealing member 120 , and the first sealing member 120 can adapt to the contour of the atomizing core 200 to prevent aerosol from leaking out from the periphery of the atomizing core 200 . At the same time, the first sealing member 120 is bonded to a part of the bracket 300, which can make the internal structure of the atomizer more compact and save the occupied space.

Wherein, the first cooling channel 301 and the second cooling channel 302 are formed by the recessed part of the bracket 300 and the first seal 120 , and the rest of the bracket 300 except the recessed part is evenly bonded and connected by the first seal 120 .

Further, the liquid accumulation chamber is formed by the recessed liquid accumulation groove 303 on the bracket 300 and the first sealing member 120 .

The base material deteriorates due to repeated heating. Wherein, the heat of the aerosol generating substrate can also be transferred to the upper cover 110 through the first sealing member 120 , and then the upper cover 110 can dissipate the heat outward.
