Furthermore, the terms "first," "second," "third," and "fourth" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

An electronic atomizer according to an embodiment of the present application is provided, with reference to fig. 1 to 3, and with reference to fig. 10 to 12, including an atomizer according to any embodiment of the present application.

The electronic atomising device is used to atomise an aerosol-generating substrate to produce an aerosol for consumption by a user. The aerosol-generating substrate includes, but is not limited to, a pharmaceutical product or the like. The aerosol-generating substrate is also not limited to liquids or solids. The following examples are all illustrated schematically by way of example of a liquid aerosol-generating substrate.

An electronic atomizer device generally includes an atomizer and a power supply assembly for supplying power to the atomizer, the atomizer being detachably connected to the power supply assembly. Of course, the electronic atomizer may further include a housing, and both the atomizer and the power supply module may be accommodated in the housing, so as to facilitate the user to use the electronic atomizer. The atomiser converts electrical energy into heat energy and the aerosol-generating substrate is converted under the action of the heat energy into an aerosol which can be drawn by the user. In the process, after the atomization core 30 of the atomizer absorbs liquid, the aerosol generating substrate is heated and atomized through the heating body of the atomization core 30, the atomization core 30 absorbs liquid continuously while atomizing, and the outside air enters the liquid storage cavity b through the ventilation channel 80.

It should be noted that the specific type of the electronic atomization device provided in the embodiment of the present application is not limited, and for example, the electronic atomization device may be a medical atomization apparatus, an air humidifier, an electronic cigarette, or some other apparatus that needs to use an atomizer.

Referring to fig. 1 to 17, an atomizer according to an embodiment of the present invention includes a housing 20, an atomizing base 10, and a ventilation channel 80.

Referring to fig. 2 and 11, the housing 20 is provided with a receiving cavity c and an air outlet channel 21, and the aerosol generated by the aerosol-generating substrate is sucked through the air outlet channel 21 by a user, and it should be noted that the specific way of using the atomizer is not limited herein, for example, the user can suck the aerosol through the housing 20, and can also suck the aerosol through an additional suction nozzle 50 cooperating with the housing 20.

Referring to fig. 2 and 11, at least a portion of the atomizing base 1020 is disposed in the receiving cavity c, a liquid storage cavity b for storing the aerosol-generating substrate is defined between the top wall 111 of the atomizing base 10 and the housing 20, the atomizing base 10 is formed with an atomizing cavity a and at least one lower liquid channel 120, and the lower liquid channel 120 is connected between the liquid storage cavity b and the atomizing cavity a. That is, aerosol-generating substrate stored in reservoir b may enter aerosolization chamber a for heated aerosolization via lower liquid channel 120.

The atomizing base 10 is disposed in the receiving cavity c, and at least a part of the atomizing base 10 may be disposed in the receiving cavity c, or all the atomizing base 10 may be disposed in the receiving cavity c.

The aerosol generating substrate in the liquid storage cavity b is guided into the atomizing cavity a through the liquid feeding channel 120 to be heated and atomized so as to generate aerosol, and after the aerosol generating substrate in the liquid storage cavity b is consumed, outside air enters the liquid storage cavity b through the ventilation outlet 81 of the ventilation channel 80 so as to balance the pressure in the liquid storage cavity b.

In the related art, the ventilation outlet 81 of the ventilation channel 80 is usually arranged near the heating element or near the lower liquid outlet of the lower liquid channel 120, and if the ventilation outlet 81 is arranged near the heating element, bubbles generated after ventilation are retained near the heating element and cannot be discharged, and if the ventilation outlet 81 is arranged near the lower liquid outlet of the lower liquid channel 120, the viscosity of the aerosol generating substrate is higher due to the lower temperature near the lower liquid outlet, so that the ventilation bubbles are gathered to block the lower liquid outlet, the liquid absorption of the atomizing core 30 is blocked, and the unsmooth liquid drainage causes the dry burning of the atomizing core 30, thereby influencing the service life of the atomizer and the use experience of a user.

And the atomizer that this application embodiment provided, through setting up ventilation channel 80, ventilation channel 80's export 81 and stock solution chamber b intercommunication of taking a breath, aerosol in the stock solution chamber b generates the substrate and heats atomizing in liquid channel 120 water conservancy diversion to atomizing chamber a down in order to produce aerosol, aerosol supplies the user to suck through air outlet channel 21, and after aerosol generation substrate in the stock solution chamber b was consumed, external air got into stock solution chamber b through ventilation channel 80 in order to balance the pressure in the stock solution chamber b. When flowing through the air outlet channel 21, the high-temperature aerosol generated by heating and atomization exchanges heat with the side wall 112 of the air outlet channel 21, and the high-temperature aerosol, for example, exchanges heat by convection, condenses, releases heat, and the like, so that the temperature of the side wall 112 of the air outlet channel 21 is further increased, the side wall 112 of the air outlet channel 21 transfers heat to the aerosol generating substrate near the air outlet channel 21, and the viscosity of the aerosol generating substrate near the air outlet channel 21 is reduced after the aerosol generating substrate is heated and heated. Thus, by placing the ventilation outlet 81 close to the outlet passage 21, bubbles generated by the ventilation outlet 81 are formed and expanded in a region of the aerosol-generating substrate having a low viscosity. That is, by arranging the ventilation outlet 81 close to the air outlet channel 21, on the one hand, the viscosity of the aerosol-generating substrate in the vicinity of the ventilation outlet 81 can be made lower, facilitating easier entry of air into the reservoir chamber b through the ventilation channel 80, improving ventilation while preventing the ventilation channel 80 from being blocked. On the other hand, as the viscosity of the aerosol generating substrate near the air outlet channel 21 is reduced after the aerosol generating substrate is heated and heated, the expansion of the bubbles generated by the ventilation outlet 81 in the extending direction of the air outlet channel 21 is facilitated, the situation that the bubbles generated by the ventilation outlet 81 are transversely expanded to block the lower liquid channel 120 can be prevented, the bubble blocking situation of the lower liquid channel 120 can be further improved, and the service life of the atomizer is prolonged, and the use experience of a user is improved.

Wherein the ventilation outlet 81 is located close to the outlet passage 21, i.e. the ventilation outlet 81 is located as close as possible to the outlet passage 21, i.e. the ventilation outlet 81 is located in the region of the aerosol-generating substrate that has been heated to a reduced viscosity.

In one embodiment, the number of ventilation channels 80 is multiple. Illustratively, referring to fig. 4, 7 and 9 in combination with fig. 12 and 17, the number of ventilation channels 80 is 2. So, the setting of a plurality of passages of taking a breath 80 not only is convenient for during external air passes through the passage of taking a breath 80 and gets into stock solution chamber b to improve the efficiency of taking a breath, can also avoid arbitrary one passage of taking a breath 80 to block up the condition that arouses external air can't get into stock solution chamber b.

The ventilation channels 80 are symmetrically distributed along the central axis of the air outlet channel 21, so that the interference of air inlet and air outlet among the ventilation channels 80 can be avoided, and the ventilation efficiency is further improved.

In one embodiment, the number of the drain passages 120 is plural. Illustratively, referring to fig. 4 and 5 in combination with fig. 13 and 15, the number of drain passages 120 is 2. So, the setting of liquid channel 120 is not only convenient for aerosol generation matrix in the liquid storage cavity b to transmit to atomizing core 30 through liquid channel 120 down and heat the atomizing to improve atomization efficiency, can also avoid arbitrary one liquid channel 120 to block up and lead to atomizing core 30 imbibition to be obstructed, thereby lead to atomizing core 30 to burn futilely down.

The lower liquid channels 120 are symmetrically distributed along the central axis of the air outlet channel 21, so that the interference of the lower liquid among the lower liquid channels 120 can be avoided, and the smoothness of the lower liquid can be improved.

In one embodiment, referring to fig. 4 and 13, the ventilation outlet 81 is disposed away from the liquid inlet of the liquid outlet channel 120. That is, while the ventilation outlet 81 is disposed as close to the air outlet channel 21 as possible, the ventilation outlet 81 is disposed as far away from the liquid inlet of the lower liquid channel 120 as possible, so that the possibility of the liquid inlet of the lower liquid channel 120 being blocked by bubbles generated from the ventilation outlet 81 is further reduced.

For example, 2 lower liquid channels 120 are symmetrically arranged on the atomizing base 10, and the air vent 81 is arranged in a direction perpendicular to the central axis of the 2 lower liquid channels 120, so that the air vent 81 can be arranged as far away from the liquid inlet of the lower liquid channels 120 as possible.

In one embodiment, referring to fig. 2 and 3 in combination with fig. 11 and 12, the atomizer includes an atomizing core 30 disposed in an atomizing cavity a, the atomizing core 30 includes a heating element (not shown), the aerosol-generating substrate in the liquid storage cavity b is guided to the atomizing core 30 through the liquid discharge channel 120, and the heating element can heat and atomize the aerosol-generating substrate. The seal gasket 31 can be arranged outside the atomizing core 30, so that the atomizing core 30 can be mounted and absorb liquid conveniently.

In one embodiment, referring to fig. 9 and 11, the ventilation channel 80 has a ventilation inlet 82 disposed in the atomizing chamber a, and the ventilation inlet 82 is disposed in the region of the atomizing base 10 around the heating element, i.e. near the heating element. That is to say, the air current that gets into ventilation passageway 80 from ventilation inlet 82 can preheat through the heat-generating body, and the air current that gets into ventilation passageway 80 can be through the air current of preheating, and the temperature is higher, on the one hand, can prevent to reduce the aerosol formation substrate's of ventilation export 81 when the cold air current gets into liquid storage cavity b temperature, and then be unfavorable for the smoothness that the air current got into liquid storage cavity b through ventilation passageway 80, on the other hand, the air current after preheating carries out the heat transfer with the aerosol formation substrate of ventilation export 81 department to further reduce the viscosity of the aerosol formation substrate of ventilation export 81 department, further improved ventilation efficiency.

In one embodiment, referring to fig. 5 and 15, the atomizing base 10 is provided with an air guide channel 131 and an air vent 132, wherein the air guide channel 131 includes an open end 1311 (i.e., the upper end of the air guide channel 131 illustrated in fig. 5 and 15 is provided with an opening) and a closed end 1312 opposite to the open end 1311 (i.e., the lower end of the air guide channel 131 illustrated in fig. 5 and 15). The air vents 132 are spaced apart on both sides of the central axis of the air guide channel 131 in a first direction (the front-rear direction shown in fig. 13), and the air guide channel 131 communicates with the atomizing chamber a through the air vents 132 and with the air outlet channel 21 through the open end 1311. Wherein the first direction is perpendicular to the central axis of the air guide channel 131. Thus, the aerosol in the atomizing cavity a enters the air guide channel 131 through the vent 132 and then enters the air outlet channel 21 through the open end 1311 of the atomizing cavity a, which not only effectively utilizes the space, but also is convenient for the user to use.

In one embodiment, the ventilation outlet 81 is provided at least one side of the air guide channel 131 in the first direction (the front-rear direction illustrated in fig. 13). It can be understood that, in order to avoid the interference between the air flow channel between the air vent 132 and the air guide channel 131 and the lower liquid channel 120, the installation space is effectively utilized, the air vent 132 is disposed on both sides of the central axis of the air guide channel 131 along the first direction, the lower liquid channel 120 is disposed on both sides of the central axis of the air guide channel 131 along the second direction (the left-right direction illustrated in fig. 13) perpendicular to the first direction, and the ventilation outlet 81 is disposed on at least one side of the air guide channel 131 along the first direction, that is, the ventilation outlet 81 is disposed as close to the air outlet channel 21 as possible, and the ventilation outlet 81 is disposed as far from the liquid inlet of the lower liquid channel 120 as possible, so that the possibility that the liquid inlet of the lower liquid channel 120 is blocked by the bubbles generated by the ventilation outlet 81 is further reduced.

Referring to fig. 2 and 11, an air inlet channel 22 is further formed inside the housing 20, the air outlet channel 21 is communicated with the top end of the atomizing chamber a, and the air inlet channel 22 is communicated with the bottom end of the atomizing chamber a.

Optionally, one end of the air outlet channel 21 is communicated with the open end 1311 of the air guide channel 131 shown in some embodiments, and the other end of the air outlet channel 21 is communicated with the suction nozzle 50 to realize the air suction process.

The atomizing core 30 is arranged in the atomizing chamber a and the lower liquid channel 120 guides the aerosol-generating substrate to the atomizing surface of the atomizing core 30 located in the atomizing chamber a. When a heating element (not shown) in the atomizer is energized to convert electric energy into heat energy, the liquid absorbed by the atomizing core 30 is atomized to form aerosol and discharged into the atomizing cavity a, and when the air suction action of the air flow is generated in the air outlet channel 21, the aerosol in the atomizing cavity a enters the air outlet channel 21 to be used by a user.

It can be understood that, referring to fig. 4 and 5, the boss 130 is protruded from the top wall 111, the lower liquid channel 120 is disposed on the top wall 111, and the ventilation outlet 81 is formed on the boss 130, that is, the ventilation outlet 81 is higher than the lower liquid opening of the lower liquid channel 120, so that the bubbles generated by the ventilation outlet 81 will expand upwards, the ventilation bubbles can be prevented from blocking the lower liquid opening of the lower liquid channel 120, the bubble blockage of the lower liquid channel 120 can be further improved, and the service life of the atomizer and the use experience of the user can be improved. In addition, since the air guide passage 131 communicates with the air outlet passage 21 through the open end 1311, and thus the ventilation outlet 81 is disposed near the open end 1311, it is possible to dispose the ventilation outlet 81 as close to the air outlet passage 21 as possible.

Referring to fig. 4, a first ventilation groove 113 communicating with the ventilation outlet 81 is formed on the outer peripheral wall of the top seat body 110, and an end of the first ventilation groove 113 far away from the ventilation outlet 81 communicates with the atomization chamber a. The aerosol-generating substrate flows from within the reservoir b into the lower liquid channel 120, which lower liquid channel 120 directs the aerosol-generating substrate to the atomising surface of the atomising cartridge 30 located in the atomising chamber a. When a heating element (not shown) in the atomizer is energized to convert electric energy into heat energy, the liquid absorbed by the atomizing core 30 is atomized to form aerosol and discharged into the atomizing cavity a, and when the air suction action of the air flow is generated at the air outlet channel 21, the aerosol in the atomizing cavity a enters the air outlet channel 21 to be used by a user. Meanwhile, the external air flow may be transmitted to the ventilation outlet 81 through the first ventilation slot 113 and enter the liquid storage chamber b, so as to realize ventilation in the liquid storage chamber b.

In one embodiment, referring to fig. 4 and 6, the first ventilation slot 113 includes a first sub-slot 1131 connected to the ventilation outlet 81 and a second sub-slot 1132 connected to the atomizing chamber a, the first sub-slot 1131 is disposed on the top wall 111 and the outer peripheral wall of the boss 130, and the second sub-slot 1132 is disposed on the outer peripheral wall of the side wall 112. In this embodiment, one end of the second sub-slot 1132 communicated with the atomizing chamber a is disposed close to the heating element, and the external airflow flows from the second sub-slot 1132 to the first sub-slot 1131, and then enters the liquid storage chamber b through the ventilation outlet 81 of the ventilation channel 80 to perform ventilation.

It should be noted that the specific location of the first sub-groove 1131 is not limited herein, for example, the first sub-groove 1131 is disposed near the air guide channel 131, and the temperature near the air guide channel 131 is higher, so as to reduce the viscosity of the aerosol-generating substrate entering the first sub-groove 1131, and further facilitate the smoothness of the air flow entering the liquid storage cavity b through the air exchange channel 80.

It should be noted that there are various ways for the first sub-groove 1131 to communicate with the second sub-groove 1132, and the first sub-groove 1131 may be directly communicated or indirectly communicated, and for example, in an embodiment, referring to fig. 6 to fig. 9, the outer peripheral wall of the atomizing base 200 is formed with a second ventilation groove 210, and one end of the first sub-groove 1131, which is far away from the ventilation outlet 81, is communicated with the second sub-groove 1132 through the second ventilation groove 210. Thus, the external air flow flows into the second sub-groove 1132 from the atomizer, flows through the second ventilation groove 210 from the second sub-groove 1132, flows into the first sub-groove 1131, and enters the liquid storage chamber b through the ventilation outlet 81 of the ventilation channel 80 for ventilation.

In other embodiments, an end of the first sub-groove 1131 away from the ventilation outlet 81 is connected to the second sub-groove 1132. That is, the first sub-slot 1131 directly communicates with the second sub-slot 1132.

In an embodiment, referring to fig. 6 to 9, the number of the second ventilation slots 210 is multiple, and the second ventilation slots 210 are sequentially communicated. The plurality of second ventilation grooves 210 which are communicated in sequence are arranged for preventing the aerosol generating substrate in the liquid storage cavity b from leaking after entering the ventilation channel 80 through the ventilation outlet 81. For example, when the air pressure in the reservoir b becomes low (e.g., when the electronic atomizer is transported by aircraft), the volume of the air bubbles in the reservoir b becomes large, and the aerosol-generating substrate overflowing through the second sub-slot 1132 may be accommodated in a plurality of second ventilation slots 210 that are connected in series, thereby improving leakage. When the air pressure in the liquid storage chamber b is recovered to normal, the aerosol-generating substrate stored in the second ventilation groove 210 may flow back into the liquid storage chamber b through the second sub-groove 1132, thereby improving the negative pressure leakage.

In one embodiment, with continued reference to fig. 6 to 9, the atomizing base 200 is formed with a first vent groove 220 formed on an outer peripheral wall thereof for communicating the second vent grooves 210. That is, the second ventilation grooves 210 communicate with each other through the first ventilation groove 220. The number of the first ventilation grooves 220 is not limited herein, and may be one or more.

In an embodiment, with reference to fig. 6 to 9, the number of the second sub-slots 1132 is multiple, and each of the second sub-slots 1132 is in butt-joint communication with the corresponding second ventilation slot 210. It can be understood that, a plurality of second subslots 1132 are communicated with atomizing chamber a, that is to say, the air current in atomizing chamber a can enter second air exchange groove 210 from a plurality of second subslots 1132 simultaneously, and enter reservoir b through second air exchange groove 210, so, a plurality of second subslots 1132 not only are convenient for the air current in atomizing chamber a to enter reservoir b in a larger amount, so as to improve the air exchange efficiency, but also can avoid the condition that any one second subslot 1132 is blocked to cause unable air exchange.

In an embodiment, referring to fig. 2, fig. 3 and fig. 9, the atomizer further includes a first sealing member 40, the first sealing member 40 is disposed at a top end of the atomizing top base 100, some installation gaps may exist between the atomizing top base 100 and the sidewall 112 of the receiving cavity c, and the first sealing member 40 is disposed at the top end of the atomizing top base 100 for sealing the installation gap between the atomizing top base 100 and the sidewall 112 of the receiving cavity c, so as to prevent the aerosol-generating substrate in the liquid storage cavity b from flowing into the receiving cavity c through the installation gap between the atomizing top base 100 and the sidewall 112 of the receiving cavity c, thereby causing liquid leakage.

A part of the ventilation channel 80 is defined between the first sealing element 40 and the wall of the first sub-groove 1131, the side wall 112 of the accommodating cavity c and the second sub-groove 1132 are defined, and another part of the ventilation channel 80 is defined between the wall of the ventilation channel in the second embodiment; the first sealing member 40 is further provided with a first ventilating hole 41, and the first ventilating hole 41 is communicated between the liquid storage cavity b and the ventilating outlet 81. Thus, the external air flow flows to the ventilation outlet 81 through the ventilation channel 80 and then enters the liquid storage cavity b through the ventilation hole, so as to realize ventilation of the liquid storage cavity b.
