The atomization assembly provided by the embodiment of the invention has at least the following beneficial effects:

(1) compared with the atomization assembly which directly injects all the tobacco tar into a cavity, the atomization assembly provided by the invention can reduce the amount of the tobacco tar with higher fluidity in the atomization assembly and reduce the pressure of the tobacco tar, thereby reducing the oil leakage risk (including the risk of leakage into a channel for flowing the tobacco tar and the risk of leakage out of a base) of the atomization assembly. The oil storage cotton has a certain volume, and for the same cavity, when the oil storage cotton is arranged in the cavity, the oil storage amount in the cavity is less than that when the oil storage cotton is not arranged in the cavity; compared with the method that all tobacco tar is stored in the oil storage cotton, the atomization assembly only stores a part of tobacco tar in the oil storage cotton, and the atomization assembly can store more tobacco tar. Therefore, the atomization assembly has both larger oil storage capacity and better oil leakage prevention performance.

(2) Due to the fact that the oil storage cotton is arranged, the tobacco tar pressure near the atomizing core is low, the oil inlet speed of the atomizing core cannot be too high, liquid tobacco tar cannot easily permeate into the second air passage of the atomizing core, liquid drops in a flue can be reduced, the situation that air flow generates 'guru-and-snore' when flowing through the liquid drops is reduced, and therefore the situation that a user hears noise when using the atomizing assembly is reduced.

Generally, it is often desirable to have the oil intake rate slightly greater than the atomization rate to ensure the user's continuance of smoking and smoke taste; thus, an atomizing core is generally suitable for only a few types of tobacco products. If atomization component is provided with the oil storage cotton, the difference of the speed that different tobacco oils got into the atomizing core is less so, is guaranteeing that the oil feed speed of atomizing core slightly is greater than under the condition of atomizing speed, and this atomization component can be applicable to more tobacco oils, and atomization component's suitability is high.

Furthermore, the particular features, structures, materials, or characteristics described may be combined in any suitable manner in any one or more embodiments or examples.

The invention provides an atomization assembly which comprises a first shell 204, a base 218, a partition 205, oil storage cotton 208 and an atomization core 221. In the electronic atomizer 101, the atomizing component can be used in cooperation with a power supply component, and the power supply component can supply power to the atomizing component, so that the tobacco tar in the atomizing component is atomized.

Referring to fig. 2, 3 and 5, the first housing 204 is hollow, and the first housing 204 is connected to the base 218, so that an accommodating chamber 502 is formed inside the first housing 204. The first housing 204 has a flue tube 301, the flue tube 301 is disposed in the accommodation chamber 502, and the flue tube 301 has a smoke outlet channel 303 inside. The partition 205 is disposed in the accommodation chamber 502, and the partition 205 partitions the accommodation chamber 502 and forms the first oil reservoir chamber 304 and the second oil reservoir chamber 501; the space on the side of the partition 205 facing the base 218 is the second oil reservoir 501, and the space on the side of the partition 205 facing the flue pipe 301 is the first oil reservoir 304. Referring to fig. 6, the partition 205 is opened with an oil passing hole 606, and both the first oil storage chamber 304 and the second oil storage chamber 501 communicate with the oil passing hole 606. It should be noted that the cross section corresponding to fig. 3 and 5 is not cut to the oil passing hole 606, so the oil passing hole 606 is not shown in fig. 3 and 5.

Referring to fig. 3 and 5, the first oil chamber 304 and the second oil chamber 501 are used for storing tobacco tar (tobacco tar is not shown), but the storage manner is slightly different. The oil cotton 208 is arranged in the second oil chamber 501, the tobacco tar in the first oil chamber 304 directly fills the first oil chamber 304, and the tobacco tar in the second oil chamber 501 is absorbed in the oil cotton 208. A part of the atomizing core 221 is arranged in the second oil storage cavity 501, the oil storage cotton 208 is in contact with the atomizing core 221, the atomizing core 221 can generate heat, and smoke is generated after the tobacco tar in the oil storage cotton 208 is heated. Referring to fig. 3, the partition 205 has a first air passage 305, the atomizing core 221 has a second air passage 306, and both ends of the first air passage 305 are respectively communicated with the second air passage 306 and the smoke outlet channel 303; if the path through which the smoke flows is referred to as a flue, the flue includes a first air path 305, a second air path 306, and a smoke outlet path 303.

The atomization assembly generally operates on the following principle: the smoke oil in the oil storage cotton 208 is heated to generate smoke, the smoke is driven to flow through the second air passage 306, the first air passage 305 and the smoke outlet passage 303 in sequence by the pressure difference generated by the smoking action of the user, and the smoke finally flows out of the flue; as the tobacco tar in the oil cotton 208 is consumed, the tobacco tar in the first oil storage chamber 304 flows from the oil passing hole 606 to the second oil storage chamber 501, and is adsorbed by the oil cotton 208 in the second oil storage chamber 501, so that the tobacco tar is supplemented to the oil cotton 208.

Compared with the atomization assembly which stores a part of the tobacco tar in the oil storage cotton 208 and stores another part of the tobacco tar in the first storage cavity, the atomization assembly provided by the invention can reduce the amount of the tobacco tar with higher fluidity in the atomization assembly and reduce the pressure of the tobacco tar, thereby reducing the oil leakage risk (including the risk of leakage into a channel for flowing the tobacco tar and the risk of leakage out of the base 218) of the atomization assembly compared with the mode that all the tobacco tar is directly injected into a cavity. The oil storage cotton 208 has a certain volume, and for the same cavity, when the oil storage cotton 208 is arranged in the cavity, the oil storage amount in the cavity is less than that when the oil storage cotton 208 is not arranged in the cavity; compared with the method that all the tobacco tar is stored in the oil storage cotton 208, the atomization assembly only stores a part of the tobacco tar in the oil storage cotton 208, and the atomization assembly can store more tobacco tar. Therefore, the atomization assembly has both larger oil storage capacity and better oil leakage prevention performance.

Due to the arrangement of the oil storage cotton 208, the pressure of the tobacco tar near the atomizing core 221 is low, the oil inlet rate of the atomizing core 221 is not too high, and the liquid tobacco tar is not easy to permeate into the second air passage 306 of the atomizing core 221, so that liquid drops in a flue can be reduced, the situation that air flow generates a gurgling sound when flowing through the liquid drops is reduced, and the situation that a user hears noise when using the atomizing assembly is reduced.

In addition, the atomization assembly is provided with the oil storage cotton 208, so that the applicability of the atomization assembly can be improved. The viscosity of different kinds of tobacco tar can be different; under the condition that the power of the atomizing core 221 is constant, the atomizing rate of the atomizing core 221 is basically constant, but the rate of the tobacco smoke with different viscosity entering the atomizing core 221 (i.e. the oil feeding rate of the atomizing core 221) is different. Generally, it is often desirable to have the oil intake rate slightly greater than the atomization rate to ensure the user's continuance of smoking and smoke taste; thus, an atomizing core 221 is generally suitable for only a few types of tobacco products. If the atomizing assembly is provided with the oil storage cotton 208, the difference of the speed of different tobacco oils entering the atomizing core 221 is small, the atomizing assembly can be suitable for more tobacco oils under the condition that the oil inlet speed of the atomizing core 221 is guaranteed to be slightly larger than the atomizing speed, and the applicability of the atomizing assembly is high.

In the atomizing assembly of the present invention, the sum of the oil storage amount of the first oil storage chamber 304 and the oil storage amount of the second oil storage chamber 501 can be set to be not less than 10ml, so as to reduce the frequency of replacing the atomizing assembly or adding the tobacco tar again by a user, thereby improving the convenience of the atomizing assembly. As described above, due to the oil storage cotton 208 arranged in the atomization assembly, the atomization assembly is not easy to leak oil even if the total amount of the tobacco tar is more than 10 ml. It should be noted that the oil storage capacity of the first oil storage chamber 304 is directly dependent on the size of the first oil storage chamber 304, and the oil storage capacity of the second oil storage chamber 501 is mainly dependent on the size of the second oil storage chamber 501 and the adsorption capacity of the oil cotton 208 to the smoke.

Other configurations of the atomizing assembly are described in more detail below.

Referring to fig. 2-4, in some embodiments, the atomization assembly further includes a suction nozzle 202 and a host plug 201, the suction nozzle 202 is attached to an end of the first housing 204, and the suction nozzle 202 is configured to contact a user's mouth. The main plug 201 is used for blocking the suction nozzle 202, so as to prevent dust from falling into the flue to cause sanitary problems when the atomization assembly is idle. Referring to FIG. 10, in some embodiments, it is also contemplated that the suction nozzle 202 and the first housing 204 may be integrally formed.

Referring to fig. 14, in some embodiments, the atomizing core 221 includes a core tube 211, a fixing ring 212, an oil guide cotton 209, and a heating wire 210. The core tube 211 is mounted on the base 218, the fixing ring 212 is mounted at the bottom of the core tube 211, the fixing ring 212 is connected to the heating wire 210, so as to fix the position of the heating wire 210, and the lead of the heating wire 210 passes through the fixing ring 212. The oil guide cotton 209 is connected to the inner wall of the core tube 211, and the inner surface of the oil guide cotton 209 serves as a part of the wall surface of the second air duct 306. The heating wire 210 is connected with the oil guide cotton 209, and the heating wire 210 can be directly connected with the inner side surface of the oil guide cotton 209 so as to reduce the connection difficulty of the heating wire and the oil guide cotton; in other embodiments, it is also contemplated that the heating wire 210 may be inserted inside the oil cotton 209.

Referring to fig. 14, the oil guide cotton 209 has a positioning channel 1301 at the center thereof, and a portion of the core tube 211 may be inserted into the positioning channel 1301. The core tube 211 is provided with an escape opening 1401, and at least one of the oil guide cotton 209 and the oil storage cotton 208 passes through the escape opening 1401, so that the oil guide cotton 209 and the oil storage cotton 208 are contacted. The oil cotton 209 can penetrate out of the core tube 211 to contact with the oil cotton 208; or the oil storage cotton 208 is squeezed into the core tube 211 to contact with the oil guide cotton 209; the oil guide cotton 209 and the oil storage cotton 208 may have a part thereof pushed into the escape opening 1401, and the two parts may contact each other. The oil guide cotton 209 can also adsorb the tobacco tar, after the oil guide cotton 209 contacts the oil storage cotton 208, the tobacco tar in the oil storage cotton 208 can be transferred into the oil guide cotton 209, the heating wire generates heat to atomize the tobacco tar in the oil guide cotton 209, and the smoke then enters the second air passage 306.

Referring to fig. 2, in some embodiments, the oil guide cotton 209 may be provided in a cylindrical shape, and an outer wall of the oil guide cotton 209 is in contact with an inner wall of the oil storage cotton 208. Referring to fig. 14, in some embodiments, a deformation seam 1302 may also be disposed on the oil cotton 208, the deformation seam 1302 is communicated with the positioning channel 1301, a part of the oil cotton 209 surrounds the outside of the heating wire 210, and another part of the oil cotton 209 passes through the escape opening 1401 and is disposed in the deformation seam 1302. The oil guide pad 209 can be held between the oil reservoir pad 208 and the wall surface of the deformation joint 1302. In contrast, in the manner shown in fig. 14, the contact area between the oil storage cotton 208 and the oil guide cotton 209 can be increased, and the oil inlet rate of the atomizing core 221 can be increased.

Oil holes 401 may be provided in the first housing 204 or base 218 to facilitate the addition of oil to the atomizing assembly. The oil filler hole 401 communicates with the first oil reservoir chamber 304, and the smoke enters the first oil reservoir chamber 304 from the oil filler hole 401, and a part of the smoke enters the second oil reservoir chamber 501 from the oil passing hole 606. The atomization assembly further comprises an oil filling plug 203, and the oil filling plug 203 can block the oil filling hole 401 to prevent oil leakage. The oil plug 203 abuts against the wall of the oil hole 401 to close the oil hole 401, and the smoke is prevented from leaking out of the oil hole 401. The oil plug 203 may be made of some elastic material to improve the sealing effect, such as silicone rubber.

Fig. 4 shows a case where the oil filler hole 401 is provided in the first housing 204. Referring to fig. 11 to 13, in some embodiments, a side portion of the partition 205 is spaced apart from an inner wall of the first housing 204 to form a filler passage 1101, the filler passage 1101 being a portion of the first oil reservoir chamber 304, the filler hole 401 communicating with one end of the filler passage 1101. This arrangement is suitable for situations where the first housing 204 is not convenient for opening the oil hole; for example, in fig. 10, the suction nozzle 202 is integrated with the first housing 204, and the design shown in fig. 4 cannot be adopted.

Referring to fig. 11 and 12, in some embodiments, a side of the partition 205 facing the oil filling passage 1101 (e.g., a right side of the partition 205 in fig. 12) is provided with at least one oil passing hole 606, thereby improving utilization of the soot. If the oil passing hole 606 is not provided at this portion of the partition 205, it is difficult for the part of the soot in the oil filling passage 1101 to enter the second oil reservoir chamber 501, i.e., the part of the soot is wasted.

Referring to fig. 6, in some embodiments, the divider 205 includes a divider 603 and a first sleeve 601. The first sleeve portion 601 is disposed in a hollow manner, a hollow space inside the first sleeve portion 601 serves as a part of the first air passage 305, an outer edge of the partition portion 603 abuts against an inner wall of the first housing 204, and two sides of the partition portion 603 are the first oil storage chamber 304 and the second oil storage chamber 501, respectively. The protruding first sleeve portion 601 facilitates mating with other components in the atomization assembly (the flue tube 301 is sleeved outside the first sleeve portion 601) to enable positioning of the partition 205 in the atomization assembly.

Referring to fig. 6, in some embodiments, the outer wall of the first sleeve 601 has a first annular rib 604, the first annular rib 604 has elasticity, and the first annular rib 604 abuts against the inner wall of the smoke outlet channel 303, so as to block the smoke from entering the smoke outlet channel 303 from the gap between the flue pipe 301 and the first sleeve 601 (i.e., prevent the smoke from leaking into the smoke outlet channel 303).

Similarly, in some embodiments, the outer edge of the partition 603 has a second annular rib 605, the second annular rib 605 has elasticity, and the second annular rib 605 abuts against the inner wall of the first housing 204. The second annular rib 605 serves to block the flow of soot from the gap between the partition 205 and the first housing 204 into the second oil reservoir chamber 501. If the smoke flows from the gap between the partition 205 and the first housing 204 to the second oil storage chamber 501, the smoke entering the second oil storage chamber 501 in the same time period will increase, which easily results in a larger actual oil feeding rate of the atomizing core 221, and affects the normal operation of the atomizing assembly. The second annular rib 605 is provided to ensure that the atomizing assembly can operate according to a predetermined operating condition.

In some embodiments, the divider 205 may be provided as an integrally formed piece of silicone. In other embodiments, a plastic part may be formed by injection molding, the shape of the plastic part is similar to that of the partition 205 shown in fig. 6, but the plastic part is not provided with the first annular rib 604 and the second annular rib 605, and the plastic part is provided with an annular groove corresponding to the first annular rib 604 and the second annular rib 605; a silicone ring is then installed into these annular grooves as a first annular rib 604 and a second annular rib 605. The latter arrangement is similar to the fit between a piston and a piston ring.

The partition 205 further includes a second sleeve portion 602, the second sleeve portion 602 being connected to a side of the partition 603 facing the second oil reservoir chamber 501, an inner cavity of the second sleeve portion 602 serving as a part of the first gas passage 305. The second sleeve portion 602 and the atomizing core 221 are connected to each other, and the second sleeve portion 602 is also inserted into the positioning passage. After the partition 205 and the first housing 204 are assembled, the producer can directly sleeve the oil-storing cotton 208 on the second sleeve part 602, and the second sleeve part 602 can enhance the positioning effect on the oil-storing cotton 208, thereby facilitating the assembly of the atomizing assembly.

It should be noted that, as shown in fig. 9 to 12, in some embodiments, the partition 205 is not provided with the second sleeve portion 602, and the mutual positioning between the partition 205 and the atomizing core 221 may be realized by one first adapter tube 904, and both ends of the first adapter tube 904 are respectively sleeved with the partition 205 and the atomizing core 221. Similarly, the mutual positioning between the first sleeve portion 601 and the flue pipe 301 may be achieved by the second adapter 901.
