An embodiment of the present application provides an electronic atomizer 1000, which includes an atomizer 100 and a power supply assembly 500, wherein the power supply assembly 500 is coupled to an end of the atomizer 100 for supplying power to the atomizer 100. The nebulizer 100 comprises a housing 20 and a nebulizing assembly 40, the housing 20 being for storing an aerosol-generating substrate in a liquid state, the nebulizing assembly 40 being coupled to one end of the housing 20. In use, the nebulising assembly 40, under the influence of the electrical energy from the power supply assembly 500, heats the aerosol-generating substrate stored within the housing 20 to produce an aerosol for the user to inhale. It should be noted that the structure of the power module 500 is not a main application point of the present application, and therefore, is not described herein.

The housing 20 is a hollow cylindrical structure, and includes a main housing 21 and a base 23, the main housing 21 is a hollow cylindrical structure with an opening at one end, and includes a housing top wall 212 and a housing side wall 214 extending from the housing top wall 212 toward the same direction, and the housing side wall 214 circumferentially surrounds the housing top wall 212 to form a receiving cavity with an opening at one end. The base 23 is coupled to the outer end of the housing sidewall 214 remote from the housing top wall 212 to close the open end of the main housing 21. It is to be understood that the shape of the housing 20 is not limited thereto and may be differently shaped as desired to meet different requirements.

In the following embodiments, the longitudinal direction is defined as a height direction of the housing 20 (i.e., Z direction in fig. 2), the first transverse direction is a length direction of the main housing 21 (i.e., X direction in fig. 2), and the second transverse direction is a width direction of the main housing 21 (i.e., Y direction in fig. 2). The longitudinal direction, the first transverse direction and the second transverse direction are mutually perpendicular to each other, and the first transverse direction and the second transverse direction are both located on a cross section of the shell 20 perpendicular to the longitudinal direction.

Further, the main housing 21 has a reservoir 25 for storing an aerosol-generating substrate therein and an outlet channel 27 for outputting the aerosol. Wherein, the liquid storage cavity 25 and the air outlet channel 27 are arranged at a first transverse interval, and the liquid storage cavity 25 extends longitudinally from one end of the main shell 21 connected with the base 23, and the air outlet channel 27 extends longitudinally from one end of the main shell 21 close to the base 23 and penetrates through the top wall 212 of the housing. Meanwhile, the air outlet channel 27 is provided centrally in the second transverse direction, that is, the air outlet channel 27 is equally spaced with respect to both housing side walls 214 of the housing 20 in the second transverse direction.

Referring to fig. 5 and 6, fig. 5 is an exploded view of an atomizer according to an embodiment of the present disclosure, and fig. 6 is a schematic structural view of an atomizing top cover of the atomizer according to an embodiment of the present disclosure.

In this embodiment, the atomizing assembly 40 is coupled to the main housing 21 and located at an end of the main housing longitudinally adjacent to the base 23. Because the main housing 21 is a hollow cylindrical structure with an open end, when the atomizing assembly 40 is coupled in the main housing 21, the main housing 21 and the atomizing assembly 40 jointly define a liquid storage chamber 25 for storing an aerosol-generating substrate. It will be appreciated that in other embodiments, the reservoir 25 itself is a closed structure formed in the main housing 21 and capable of storing the aerosol-generating substrate, and need not be sealed by the mating of the atomizing assembly 40, as long as the reservoir 25 is capable of storing the aerosol-generating substrate, and is not limited thereto.

Specifically, the atomizing assembly 40 includes an atomizing base 41 having an atomizing chamber and an atomizing core 43 accommodated in the atomizing chamber. The atomizing base 41 is provided with at least one lower liquid opening 4142a and at least one air outlet 4142b, and the lower liquid opening 4142a is used for supplying aerosol-generating substrate to the atomizing core 43 in the atomizing cavity from the liquid storage cavity 25. The air outlet 4142b is communicated with the atomizing cavity and the air outlet channel 27, and is used for enabling the aerosol generated by heating the atomizing core 43 to flow out of the atomizing cavity into the air outlet channel 27 for the user to suck.

In the present application, the lower liquid outlet 4142a is located on one side of the atomizing base 41 away from the air outlet channel 27 and directly below the liquid storage cavity 25, and the air outlet 4142b is located on the other side of the atomizing base 41 close to the air outlet channel 27 and on one side of the liquid storage cavity 25 in the first transverse direction.

In this way, the lower liquid outlet 4142a and the air outlet 4142b are respectively located on both sides of the atomizing base 41 in the first transverse direction, so that the aerosol flowing out of the air outlet 4142b can rapidly enter the air outlet channel 27 on that side without passing through the lower liquid outlet 4142a, thereby preventing the lower liquid outlet 4142a and the air outlet 4142b from interfering and causing the aerosol-generating substrate to leak through the air outlet 4142b, and meanwhile, the aerosol flowing out of the air outlet 4142b can rapidly enter the air outlet 4142b, thereby reducing the on-way resistance of the aerosol flow.

In some embodiments, the atomizing top cap 414 has a lower liquid outlet 4142a and two air outlets 4142b, the two air outlets 4142b are located on a side of the atomizing base 41 close to the air outlet channel 27 in the first transverse direction, the lower liquid outlet 4142a is located on a side of the two air outlets 4142b far from the air outlet channel 27, and the two air outlets 4142b are located on two sides of the lower liquid outlet 4142a in the second transverse direction.

Therefore, the aerosol in the atomizing chamber flows out through the two air outlets 4142b and then converges into the air outlet channel 27. Compared with the case where only one air outlet 4142b is provided, the aerosol can be sufficiently released through the two air outlets 4142b, so that the air output of the air outlet channel 27 is increased.

The atomizing base 41 includes an atomizing base 412, an atomizing top cover 414 and a top cover sealing member 416, the atomizing base 412 and the atomizing top cover 414 are mutually buckled to form an atomizing cavity for accommodating the atomizing core 43, and the top cover sealing member 416 covers one end of the atomizing top cover 414 far away from the atomizing base 412 to seal a gap between the outer shell 20 and the atomizing top cover 414.

Specifically, the atomizing base 412 is a housing structure, and includes a base bottom wall and a base side wall extending from the edge of the base bottom wall toward the same direction, the base side wall circumferentially surrounds the base bottom wall to form a base accommodating cavity 4121 with an opening at one end, and the base side wall is provided with a clamping groove 4123 for being coupled with the atomizing top cover 414.

The atomizing top cover 414 is a housing structure, and includes a top cover top wall 4141 and a top cover side wall 4144 extending from the edge of the top cover top wall 4141 toward the same direction, wherein one end of the top cover side wall 4144, which is away from the top cover top wall 4141, is inserted into the base accommodating cavity 4121 of the atomizing base 412, one end of the top cover side wall 4144, which is inserted into the base accommodating cavity 4121, is provided with a connecting buckle 4145, and the connecting buckle 4145 is clamped in a clamping groove 4123 formed in the base side wall. The lower liquid outlet 4142a and the air outlet 4142b are both opened at one end of the atomizing top cap 414 extending out of the base accommodating chamber 4121.

The cap seal 416 is formed of a resilient material such as silicone or the like, and includes a seal top wall that covers the outer surface of the cap top wall 4141 of the atomizing cap 414 and a seal side wall circumferentially surrounding the cap side wall 4144 and joining one side of the cap top wall 4141. When the atomization assembly 40 is coupled to one end of the housing 20, a side surface of the seal top wall of the top cap seal 416 facing away from the atomization top cap 414 contacts the reservoir 25, and a seal side wall of the top cap seal 416 may seal a gap between the atomization top cap 414 and the housing 20.

In some embodiments, the liquid inlet end of the lower liquid outlet 4142a and the gas outlet end of the gas outlet 4142b are respectively formed on different planes of the atomizing base 41 spaced apart in the longitudinal direction thereof so as to be staggered in the longitudinal direction of the atomizing base 41. In this way, since the liquid inlet end of the liquid outlet 4142a and the gas outlet end of the gas outlet 4142b are located on different planes of the atomizing base 41 and have a certain height difference in the longitudinal direction, the aerosol-generating substrate entering the atomizing base 41 through the liquid outlet 4142a and the aerosol flowing out of the atomizing base 41 through the gas outlet 4142b are prevented from interfering with each other, thereby preventing the aerosol-generating substrate from leaking through the gas outlet 4142 b.

Specifically, the top cap top wall 4141 of the atomizing top cap 414 has a first face 4142 and a second face 4143, the first face 4142 and the second face 4143 are longitudinally spaced apart and parallel, and the first face 4142 is spaced from the reservoir 25 a lesser distance than the second face 4143 is spaced from the reservoir 25. The liquid inlet end of the lower liquid port 4142a is formed on the first end face 4142, the gas outlet end of the gas outlet 4142b is formed on the second end face 4143, the sealing top wall of the top cover sealing part 416 covers the first end face 4142, the sealing top wall is provided with a communicating groove 4161 communicated with the lower liquid port 4142a and the liquid storage cavity 25 in a penetrating mode, and the shape of the communicating groove 4161 is matched with that of the lower liquid port 4142 a.

In this way, the liquid inlet end of the lower liquid port 4142a and the gas outlet end of the gas outlet 4142b are located on different planes of the atomising cap 414 and are at a different height in the longitudinal direction, and the liquid inlet end of the lower liquid port 4142a is closer to the liquid storage chamber 25, thereby facilitating the aerosol-generating substrate in the liquid storage chamber 25 to pass through the communication groove 4161 from the lower liquid port 4142a into the atomising chamber and effectively preventing the aerosol-generating substrate from flowing into the gas outlet 4142b and leaking through the gas outlet 4142 b.

Further, an orthographic projection of the gas outlet end of the gas outlet 4142b on the plane of the first end face 4142 is at least partially located on the first end face 4142, and preferably, an orthographic projection of the gas outlet end of the gas outlet 4142b on the plane of the first end face 4142 is entirely located on the first end face 4142. In this manner, the first end face 4142 blocks the open end of the reservoir 25 and shields the outlet end of the outlet 4142b, effectively preventing aerosol-generating substrate in the reservoir 25 from flowing into the outlet 4142b and leaking through the outlet 4142 b.

The atomizing core 43 is a rectangular parallelepiped structure formed of a ceramic material, and the length of the atomizing core 43 in the first transverse direction is greater than the length thereof in the second transverse direction, so that the atomizing core 43 has a length direction and a width direction respectively perpendicular to the longitudinal direction of the atomizing base 41, the length direction of the atomizing core 43 extends in the first transverse direction, and the width direction of the atomizing core 43 extends in the second transverse direction. A heating wire is attached to the surface of the atomizing core 43 on the side far away from the liquid storage cavity 25. The atomizing assembly 40 further includes a positive electrode 45 and a negative electrode 47, the positive electrode 45 and the negative electrode 47 are disposed at an interval in the first transverse direction, one end of the positive electrode 45 and one end of the negative electrode 47 are respectively connected to two opposite ends of the heating wire, and the other end of the positive electrode 45 and the other end of the negative electrode 47 are exposed out of the atomizing base 412 to be electrically connected to the power supply assembly. In this way, the power supply assembly supplies power to the heating wire through the positive electrode 45 and the negative electrode 47, the energized heating wire heats the atomizing core 43, and the atomizing core 43 gradually heats the aerosol-generating substrate to generate aerosol.

Further, along the length direction of the atomizing core 43, the atomizing core 43 is disposed in the atomizing base 41 in an offset manner, a first end of the atomizing core 43 along the length direction is close to the air outlet 4142b of the atomizing base 41, a second end of the atomizing core 43 along the length direction is far away from the air outlet 4142b of the atomizing base 41, and a liquid inlet end of the lower liquid outlet 4142a is close to a second end of the atomizing core 43 along the length direction. Along the width direction of atomizing core 43, atomizing core 43 is set up in atomizing seat 41 centrically, that is, atomizing core 43 is equal for the distance of atomizing chamber wall on the second horizontal both sides, and two gas outlets 4142b are located atomizing core 43 along the relative both sides of width direction respectively. In order to cause the aerosol-generating substrate to flow onto the eccentrically arranged atomizing core 43, the liquid inlet end of the lower liquid outlet 4142a of the atomizing cap 414 extends from the first end face 4142 in a curved manner towards the position of the atomizing core 43, so that the aerosol-generating substrate is guided onto the atomizing core 43.

Thus, the atomizing core 43 is deviated to the side where the air outlet 4142b is located and is adapted to the position of the air outlet 4142b, and the aerosol generated on the atomizing core 43 can rapidly flow out from the two sides of the atomizing core 43 through the air outlet 4142b, so that the on-way resistance of the gas flow is reduced, and the gas outlet amount of the gas outlet channel 27 is ensured.

In some embodiments, in the longitudinal direction, the plane in which the air outlet end of the air outlet 4142b lies (i.e. the second end face 4143) is higher than the top surface of the atomizing core 43 towards the lower liquid outlet 4142a, thus preventing the aerosol-generating substrate on the atomizing core 43 from flowing out of the air outlet 4142 b. Moreover, since there is a certain distance between the atomizing core 43 and the top cap wall 4144 of the atomizing top cap 414, the top cap wall 4144 can be prevented from being melted or deformed by the heat generated by the atomizing core 43 during the atomizing process. It will be appreciated that the particular distance between the atomizing core 43 and the top cap wall 4144 is not limited and can be set as desired to meet different requirements.

In some embodiments, the atomizing cap 414 is provided with a ventilation channel 4147, one end of the ventilation channel 4147 is communicated with the lower liquid port 4142a, and the other end of the ventilation channel 4147 is communicated with the sidewall of the atomizing cap 414 to communicate with the external atmosphere. Therefore, the liquid storage cavity 25 is communicated with the outside atmosphere through the ventilation channel 4147, thereby avoiding unsmooth liquid discharge caused by negative pressure formed by consumption of aerosol generating substrates in the liquid storage cavity 25.

Specifically, the atomizing top cap 414 is provided with two ventilation channels 4147, and the two ventilation channels 4147 are respectively located at two sides of the lower liquid outlet 4142a and are symmetrically arranged. Each ventilation channel 4147 comprises a first ventilation section, a second ventilation section and a third ventilation section which are sequentially communicated, wherein the first ventilation section is arranged on the side wall of the lower liquid port 4142a and extends along the longitudinal direction; the second air exchange section is arranged on the first end face 4142 of the atomizing top cover 414 provided with the lower liquid opening 4142a and extends in a zigzag manner, so that the length of the air exchange channel 4147 is increased; the third ventilation section is provided on the side wall of the atomizing head 414 near one end of the reservoir 25 and extends in the longitudinal direction.

It is understood that the number of the ventilation channels 4147 and the extending direction of the ventilation channels 4147 are not limited, and may be set according to the shape of the atomizing cap 414 and different ventilation requirements.

In some embodiments, the side wall of the atomising seat 41 at the end extending beyond the base receiving cavity 4121 is provided with at least one circumferentially extending reservoir 4146, the reservoir 4146 being arranged to provide for the absorption and storage of aerosol-generating substrate that may be present flowing from the reservoir 25, thereby preventing leakage of aerosol-generating substrate out of the atomiser 100 and thus compromising the user experience, or even damaging the battery assembly. Specifically, the atomizing base 41 is provided with a plurality of liquid reservoirs 4146, and the plurality of liquid reservoirs 4146 are arranged at intervals along the longitudinal direction. It is understood that the number and extending direction of the reservoirs 4146 are not limited and may be set as desired to meet the requirements of the user.

In the atomizer 100, the layout of the atomizing core 43 and the structure of the atomizing assembly 40 are redesigned, so that the aerosol generated by atomization can smoothly flow into the air outlet channel 27, the interference between the liquid outlet 4142a and the air outlet 4142b is avoided, and the aerosol-generating substrate is effectively prevented from flowing into the air outlet 4142b and leaking. Moreover, the aerosol in the atomizing chamber can enter the air outlet channel 27 through the two air outlets 4142b positioned at the two sides of the atomizing core 43, so that the aerosol in the atomizing chamber can be fully released, the air outlet amount of the atomizer 100 is ensured, and the user experience is effectively improved.

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.
