Referring to fig. 1 and 2, fig. 1 shows a schematic structural diagram of an atomizing assembly according to an embodiment of the present disclosure, and fig. 2 shows a schematic structural diagram of an atomizing assembly according to an embodiment of the present disclosure. An embodiment of the present application provides an electronic atomizer, which includes an atomizing assembly 100 and a battery assembly (not shown), wherein the atomizing assembly 100 includes a main housing 120 and a heating unit 140 housed in the main housing 120, the main housing 120 is used for storing an aerosol-generating substrate, the battery assembly is electrically connected to the heating unit 140, and the heating unit 140 can heat the aerosol-generating substrate under the electric energy of the battery assembly to generate an aerosol for a user to inhale.

Specifically, the main housing 120 is a hollow shell structure, and the main housing 120 has an atomizing chamber 121, an airflow channel 123 and a substrate storage chamber 125 inside. Wherein, the atomizing chamber 121 is located at one end of the main housing 120 in the axial direction and communicates with one end face of the main housing 120. One end of the air flow passage 123 is communicated with the atomizing chamber 121, and the other end of the air flow passage 123 extends along the axial direction of the main housing 120 until the other end face of the main housing 120 is communicated. The substrate storage chamber 125 extends from one end of the main housing 120 in the axial direction to the other end of the main housing 120 in the axial direction, and circumferentially surrounds the atomizing chamber 121 and the airflow passage 123.

In this manner, aerosol-generating substrate is stored in the substrate storage chamber 125 and gradually enters the nebulizing chamber 121 for heated nebulization during use of the electronic nebulizer, and aerosol generated by nebulization of the aerosol-generating substrate can flow out of the main housing 120 through the airflow channel 123 for inhalation by a user.

It will be appreciated that the shape and configuration of the main housing 120 is not limited, and the shape and positional relationship of the aerosolizing chamber 121, the airflow channel 123, and the substrate storage chamber 125 can be configured as desired to meet different requirements.

In the present application, the axial direction of the main housing 120 is the Z direction in fig. 1, the circumferential direction of the main housing 120 is a direction around the central axis of the main housing 120, and the radial direction of the main housing 120 is a direction perpendicular to the axial direction of the main housing 120 with the central axis of the main housing 120 as an origin.

Referring to fig. 3 and 4, fig. 3 is a schematic structural diagram of a heat generating unit according to an embodiment of the present application, and fig. 4 is a schematic structural diagram of a heat generating unit according to an embodiment of the present application.

The heat generating unit 140 is partially housed within the nebulizing chamber 121 for heating an aerosol-generating substrate nebulized into the nebulizing chamber 121 to generate an aerosol. Specifically, the heating unit 140 includes a liquid guide tube 141 and a heating element 143, a portion of the liquid guide tube 141 is accommodated in the atomizing chamber 121, another portion of the liquid guide tube 141 extends into the substrate storage chamber 125, and the heating element 143 is wound around the portion of the liquid guide tube 141 accommodated in the atomizing chamber 121. On one hand, the liquid guide tube 141 can play a role of supporting and fixing the heating element 143, and the heating element 143 can heat and atomize the aerosol generating substrate entering the atomizing cavity 121 to generate aerosol; alternatively, the catheter 141 may heat the aerosol-generating substrate stored within the substrate storage chamber 125.

Thus, by providing the conduit 141, the viscosity of the aerosol-generating substrate stored in the substrate storage chamber 125 may be reduced by the increase in temperature, resulting in better flowability. For example, the viscosity of the aerosol-generating substrate is up to 10 at ambient temperature ⁶ cP and when the temperature is increased to around 70 ℃, the viscosity of the aerosol-generating substrate may decrease to below 1000 cP. With the reduction of viscosity, not only is the amount of aerosol produced by the atomisation of the aerosol-generating substrate increased, but also the risk of scorching due to the inability to flow in time into the atomisation chamber 121 as a result of the excessively high viscosity is reduced, thereby improving the use experience of the electronic atomiser.

Referring again to figure 1, in some embodiments, the catheter 141 heats the aerosol-generating substrate by conducting some of the heat generated by the heating element 143 into the substrate storage chamber 125. In one embodiment, the liquid guiding tube 141 is made of a good thermal conductor, which includes but is not limited to aluminum alloy, brass, etc., so that the liquid guiding tube 141 has good thermal conductivity, and thus can efficiently conduct the heat generated by the heating element 143 into the substrate storage chamber 125. It is understood that the material forming the catheter 141 is not limited thereto, and may be provided as needed to satisfy various requirements.

Referring again to figure 2, in other embodiments the catheter 141 employs active heating to directly heat the aerosol generating substrate in the substrate storage chamber 125. In one embodiment, the liquid guide tube 141 is made of a high resistivity metal material, including but not limited to 316L, fe-cr-al, ni-cr, and the like, and the liquid guide tube 141 is electrically connected to the battery assembly through the pins 147, and the current of the battery assembly can be transmitted to the liquid guide tube 141 through the pins 147, so that the liquid guide tube 141 can generate heat under the electric energy of the battery assembly to heat the aerosol-generating substrate in the substrate storage chamber 125 without depending on the heat generated by the heating element 143. It is understood that the material forming the catheter 141 is not limited thereto, and may be provided as needed to satisfy various requirements.

In some embodiments, the catheter 141 may be operated in synchronism with the heating element 143 to heat the aerosol-generating substrate stored in the substrate storage chamber 125 while the heating element 143 is heating to aerosolize the aerosol-generating substrate. In other embodiments, the conduit 141 may also preheat the aerosol-generating substrate stored in the substrate storage chamber 125 before the heating element 143 heats the aerosol-generating substrate, thereby reducing the viscosity of the aerosol-generating substrate and increasing the flowability of the aerosol-generating substrate to ensure smooth liquid supply before the heating element 143 heats the aerosol-generating substrate.

It should be noted that in some embodiments, while the liquid conduit 141 generates heat to heat the aerosol-generating substrate under the action of electrical energy, the liquid conduit 141 may also conduct the heat generated by the heating element 143 to the substrate storage chamber 125 by way of heat conduction, thereby making full use of the heat generated by the heating element 143 to further reduce the viscosity of the aerosol-generating substrate in the substrate storage chamber 125.

As shown in fig. 1, 3 and 4, a liquid guiding cavity 1412 communicated with the substrate storage cavity 125 is formed in the liquid guiding tube 141, and a liquid guiding hole 1414 communicated with the liquid guiding cavity 1412 and the atomizing cavity 121 is formed on the wall of the liquid guiding cavity 1412. In this way, the aerosol-generating substrate in the substrate storage chamber 125 firstly enters the liquid guide chamber 1412, then flows to the atomizing chamber 121 outside the liquid guide chamber 1412 through the liquid guide holes 1414, and further contacts the heating element 143 to generate aerosol through atomization of the heating element 143. Since the liquid guide tube 141 can reduce the viscosity of the aerosol-generating substrate in its vicinity, a flow path for the ventilation bubbles can be formed to facilitate the drainage of the ventilation bubbles from the liquid guide holes 1414, thereby helping to solve the problem of clogging and accumulation of the ventilation bubbles and reducing the risk of scorching.

Furthermore, the heat generating unit 140 further includes a liquid guiding member 145, the liquid guiding member 145 covers the liquid guiding hole 1414 and covers the liquid guiding tube 141, and the heat generating element 143 is wound around the liquid guiding member 145. In this manner, aerosol-generating substrate in the liquid-directing chamber 1412 is introduced to the liquid-directing member 145 through the liquid-directing holes 1414 and uniformly distributed in the liquid-directing member 145, and the heat-generating body 143 contacts and heats the aerosol-generating substrate in the atomizing liquid-directing member 145 to generate an aerosol.

In some embodiments, catheter 141 is a tubular structure formed integrally, and catheter lumen 1412 extends through catheter 141 in an axial direction, and the sidewall of catheter 141 forms a wall of catheter lumen 1412. In embodiments where the liquid conduit 141 may actively generate heat to heat the aerosol generating substrate, two axial ends of the liquid conduit 141 respectively exit pins 147, and the two pins 147 pass through the main housing 120 to electrically connect with the positive and negative electrodes of the battery assembly respectively, thereby forming a current path to resistively heat the liquid conduit 141.

As shown in fig. 1 and fig. 2, more specifically, in one embodiment, the liquid guide tube 141 is a straight tube structure, the liquid guide tube 141 is disposed in the atomizing chamber 121 along its axial direction, the central axis direction of the liquid guide tube 141 extends along a radial direction of the main housing 120, and two axial ends of the liquid guide tube 141 respectively extend into the substrate storage chamber 125 along the radial direction. The liquid guide member 145 is circumferentially covered on the outside of the side wall of the liquid guide tube 141, and the heating element 143 is circumferentially wound around the outside of the liquid guide member 145. The side wall of the liquid guide pipe 141 is provided with a plurality of groups of liquid guide holes 1414, the plurality of groups of liquid guide holes 1414 are arranged at intervals along the axial direction of the liquid guide pipe 141, and all the liquid guide holes 1414 in each group of liquid guide holes 1414 are arranged at intervals along the circumferential direction of the liquid guide pipe 141, so that the aerosol generating substrate in the liquid guide cavity 1412 can be uniformly guided into the liquid guide piece 145.

Further, the axial length of the liquid guide tube 141 is greater than the axial length of the liquid guide 145, and at least one axial end of the liquid guide tube 141 protrudes out of the liquid guide 145 and into the substrate reservoir 125, thereby nebulizing the aerosol-generating substrate in the substrate reservoir 125. Preferably, both axial ends of the catheter 141 protrude out of the drainage member 145 and into the substrate storage chamber 125, respectively. It will be appreciated that in another embodiment, the axial length of catheter 141 may be equal to the axial length of drainage member 145, and the end faces of catheter 141 in the axial direction are flush with the end faces of drainage member 145 in the axial direction.

In particular, in embodiments where the liquid delivery tube 141 is actively heated to heat the aerosol-generating substrate, two axial ends of the liquid delivery tube 141 respectively protrude out of the liquid-guiding member 145 and extend into the substrate storage chamber 125, the two axial ends are respectively electrically connected to one end of one pin 147, and the other end of the pin 147 respectively penetrates through the main housing 120 in a direction away from the air flow channel 123 to electrically connect with the battery assembly.

In this manner, by extending into the axial end of the substrate storage chamber 125, the conduit 141 heats the aerosol-generating substrate in the substrate storage chamber 125, while the aerosol-generating substrate in the substrate storage chamber 125 can enter the conduit 1412 through the two end openings of the conduit 141 and then reach the liquid guide 145 and the heat generating body 143 through the conduit 1414.

More specifically, in some embodiments, the cross section of the catheter 141 perpendicular to the axial direction of the catheter 141 is circular, the inner diameter of the catheter 141 is 0.3mm-3mm, and the axial length of the catheter 141 is 3mm-30mm. It is understood that in other embodiments, the shape and size of catheter 141 is not limited thereto, and may be configured to meet different requirements depending on the size of main housing 120.

Referring to fig. 5 and 6, in some embodiments, catheter 141 is a generally "U" shaped tubular structure including a support section 141a and two extension sections 141b.

The supporting section 141a is at least partially located in the atomizing chamber 121 and extends along a radial direction of the main housing 120, the liquid guiding element 145 covers an outer sidewall of the supporting section 141a, and the heating element 143 is circumferentially wound around the liquid guiding element 145. A plurality of sets of the liquid guiding holes 1414 are arranged at intervals along the axial direction of the support section 141a, and all the liquid guiding holes 1414 in each set of the liquid guiding holes 1414 are arranged at intervals along the circumferential direction of the support section 141a, so that the aerosol generating substrate in the liquid guiding cavity 1412 can be uniformly guided into the liquid guiding piece 145.

The two extension segments 141b are connected to two opposite ends of the supporting segment 141a in the axial direction and extend along the radial direction of the supporting segment 141a to the end of the substrate storage chamber 125 far away from the atomizing chamber 121. Each extension 141b also has a liquid-conducting aperture 1414 formed therein, and aerosol-generating substrate in the substrate storage chamber 125 can enter the extension 141b through the liquid-conducting aperture 1414 formed in the extension 141b.

In an embodiment where the liquid guide tube 141 can actively generate heat to heat the aerosol-generating substrate, one end of each of the two extension sections 141b away from the supporting section 141a is electrically connected to one end of one of the pins 147, and the other end of the pin 147 penetrates the main housing 120 along a direction away from the airflow channel 123 to be electrically connected to the battery assembly. In some embodiments, the two pins 147 can be electrically connected to the two ends of the supporting segment 141a respectively, so as to reduce the resistance in the current path and improve the heating efficiency, and the two extending segments 141b are used for conducting the heat generated by the supporting segment 141 a.

In this way, the extension section 141b extends into the substrate storage cavity 125 to sufficiently heat the aerosol-generating substrate, thereby effectively reducing the viscosity of the aerosol-generating substrate stored in the substrate storage cavity 125, and the aerosol-generating substrate in the substrate storage cavity 125 can enter the extension section 141b through the liquid guiding hole 1414 formed in the extension section 141b. Furthermore, the aerosol-generating substrate near the extension 141b has a high temperature and a low viscosity, and therefore can serve as a passage for ventilation bubbles, which helps to solve the problem of clogging and accumulation of bubbles, and further reduces the risk of scorching. It is understood that the length of the extension 141b is not limited and may be set as needed to meet the heating requirements.

In other embodiments, catheter 141 is a generally "L" -shaped tubular structure including a support section 141a and an extension section 141b attached to either axial end of support section 141. The catheter 141 may also be substantially in an "H" shape tubular structure, and includes a supporting section 141a and four extending sections 141b, wherein two extending sections 141b are connected to one end of the supporting section 141a and are disposed along the axial direction of the main housing 120, and the other two extending sections 141b are connected to the other end of the supporting section 141a and are disposed along the axial direction of the main housing 120. The catheter 141 may also be in a substantially h-shaped tubular structure, and includes a supporting section 141a and three extending sections 141b, wherein one extending section 141b is connected to one end of the supporting section 141a and is disposed along the axial direction of the main housing 120, and the other two extending sections 141b are connected to the other end of the supporting section 141a and are disposed along the axial direction of the main housing 120. It is understood that catheter 141 may also include a support section 141a and other number of extension sections 141b, and extension sections 141b are attached to either end of support section 141a and extend toward substrate storage cavity 125, and the direction of extension is not limited.

It will be appreciated that in embodiments where the liquid delivery tube 141 is actively heated to heat the aerosol-generating substrate, one end of each of the two extension sections 141b remote from the support section 141a is electrically connected to one end of a pin 147, and the other end of the pin 147 penetrates the main housing 120 along the radial direction or axial direction of the main housing 120 to electrically connect with the battery assembly.

As shown in fig. 6 and 8, since the extension 141b is far from the heating element 143, it is difficult to conduct heat from the heating element 143 to the substrate storage chamber 125, and therefore, in an embodiment, the extension 141b is preferably provided with a plurality of heat dissipation fins 1416 in a protruding manner, and the plurality of heat dissipation fins 1416 are arranged at intervals along the extension direction of the extension 141b. The provision of the heat sink fins 1416 effectively increases the contact area of the liquid conduit 141 with the aerosol generating substrate, thereby increasing the efficiency of heat transfer. It is understood that the shape, number and arrangement of the heat dissipating fins 1416 are not limited, and may be set as required to meet different heat transfer efficiency requirements.

In the above embodiment, each liquid guide hole 1414 can be circular, and can also be regular or irregular such as oval, kidney-shaped, etc., and the equivalent diameter of each liquid guide hole 1414 is 0.01mm-3mm. It can be understood that the number, arrangement and shape of the liquid guiding holes 1414 are not limited, and the size and shape of each liquid guiding hole 1414 can be the same or different, and can be set as required to meet the requirements of different liquid guiding effects.

In some embodiments, the liquid guiding member 145 has a porous structure, such as natural organic cotton or organic synthetic polymer porous foam, and the liquid guiding member 145 has a porosity of 0.45-0.99 and a permeability of 1 × 10 ^-11 mm-1×10 ^- ⁹ mm. The aerosol-generating substrate in the liquid-conducting chamber 1412 may thus be substantially absorbed by the liquid-conducting apertures 1414 and the absorbed aerosol-generating substrate may be evenly distributed in the liquid-conducting piece 145. It is understood that in other embodiments, the material forming the fluid conducting member 145 is not limited thereto, and the material can be selected according to the requirement to meet different fluid conducting requirements, such as porous ceramic, foamed metal, etc.

The heat generating body 143 is formed of at least one of a heat generating wire, a heat generating tape, or a heat generating net having a circular cross section. Compared with the heating element in the shape of column, block, etc. in the prior art, the heating element 143 formed by the heating wire, heating belt or heating net, etc. in the present application is a thin-walled structure with a small thickness, so that the thermal resistance is small and the generated heat can be effectively conducted to the catheter 141. It is to be understood that in other embodiments, the shape and size of the heating element 143 are not limited thereto, and may be set as needed to meet different atomization requirements.

The atomizing assembly 100 and the electronic atomizer are provided with the liquid guide tube 141 having functions of liquid guiding, heat conducting (or heating) and supporting the heating element 143, and part of heat generated by the heating element 143 is conducted to the aerosol-generating substrate in the substrate storage cavity 125, or the aerosol-generating substrate in the substrate storage cavity 125 is actively heated, so that the temperature of the aerosol-generating substrate is raised and the viscosity of the aerosol-generating substrate is reduced, the amount of aerosol generated by atomization is increased, and meanwhile, the risk of scorching caused by unsmooth liquid discharge is prevented. Furthermore, since the aerosol-generating substrate in the vicinity of the liquid guide tube 141 has a low viscosity, the passage through which the ventilation bubbles can be formed helps to solve the problem of clogging and accumulation of the ventilation bubbles, reducing the risk of scorching.

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.

The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the claims. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present patent shall be subject to the appended claims.
