Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic atomization device provided in an embodiment of the present application.

In the present embodiment, an electronic atomization device 100 is provided. The electronic atomisation device 100 may be used for atomisation of an aerosol-generating substrate. The electronic atomization device 100 includes an atomizer 1 and a main body 2 electrically connected to each other.

The main body 2 further includes a battery holder, an airflow sensor, and other elements.

The atomizer 1 and the host machine 2 can be integrally arranged or detachably connected, and can be designed according to specific requirements.

Referring to fig. 2 and 3, fig. 2 is a schematic structural diagram of an atomizer of the electronic atomization device provided in fig. 1, and fig. 3 is a schematic structural diagram of a top seat of the atomizer provided in fig. 2.

The atomizer 1 includes a case 11, an atomizing base 12, and a heating body 13. One end of the shell 11 is an open end, the atomizing base 12 is arranged in the shell 11 and seals the open end, the atomizing base 12 and the shell 11 are matched to form a liquid storage cavity 10, and the liquid storage cavity 10 is used for storing aerosol generating substrates. The atomizing base 12 includes a top base 121 and a base 122, the top base 121 and the base 122 cooperate to form a mounting cavity 120, and the mounting cavity 120 is used for mounting the heating element 13. That is, the heating element 13 is provided in the mounting chamber 120, and the heating element 13 is provided in the case 11 together with the atomizing base 12. The top seat 121 is provided with a liquid outlet 1211, the heating element 13 is in fluid communication with the liquid storage chamber 10 through the liquid outlet 1211, and the heating element 13 is used for atomizing the aerosol generating substrate to generate aerosol. Wherein, the heating element 13 and the bottom wall of the installation cavity 120 are arranged at intervals to form an atomization cavity (not shown), that is, the surface of the heating element 13 far away from the liquid storage cavity 10 is matched with the cavity wall of the installation cavity 120 to form the atomization cavity. The housing 11 has a mist outlet passage 111, the top seat 121 is provided with a mist outlet hole 1210, and the mist outlet hole 1210 is communicated with the installation cavity 120, that is, the mist outlet hole 1210 is communicated with the atomizing cavity; specifically, the top seat 121 is provided with two liquid outlet holes 1211 respectively located at two sides of the mist outlet hole 1210. The aerosol generated by the heating element 13 is released into the atomizing chamber, and flows to the mist outlet channel 111 through the mist outlet holes 1210, and the user inhales the aerosol through the port of the mist outlet channel 111.

It is understood that, in the present embodiment, the atomizing base 12 is formed by assembling the top base 121 and the bottom base 122 up and down; in other embodiments, the atomizing base 12 can also be formed by assembling two structural members from left to right, and the design is specifically performed according to the requirement. That is, the present application does not limit the structure of the atomizing base 12, and the specific arrangement of the liquid discharge hole 1211 will be described in detail by taking the atomizing base 12 formed by the top base 121 and the bottom base 122 as an example.

In the embodiment of the present application, the lower liquid hole 1211 is a stepped hole, and the equivalent diameter of the portion of the lower liquid hole 1211 close to the liquid storage chamber 10 is larger than the equivalent diameter of the portion of the lower liquid hole 1211 far from the liquid storage chamber 10. Since the heating element 13 is in fluid communication with the liquid storage chamber 10 through the lower liquid hole 1211, when bubbles exist on the surface of the heating element 13 close to the liquid storage chamber 10, the bubbles can be guided to the liquid storage chamber 10, so as to avoid the bubbles from adhering to the surface of the heating element 13 close to the liquid storage chamber 10 to block the pores of the heating element 13, and further avoid the problem of insufficient liquid supply caused by the bubbles. By utilizing the characteristic that the bubbles easily flow to the open space, the lower liquid hole 1211 is arranged to be the stepped hole, the equivalent diameter of the part, close to the liquid storage cavity 10, of the lower liquid hole 1211 is larger than the equivalent diameter of the part, far away from the liquid storage cavity 10, of the lower liquid hole 1211, so that the bubbles, close to the surface of the liquid storage cavity 10, of the heating body 13 are guided to the liquid storage cavity 10, namely, the bubbles are easily separated from the lower liquid hole 1211 and enter the liquid storage cavity 10, insufficient liquid supply caused by the bubbles is avoided, and the risk of scorching or burning-off of the heating body 13 is reduced. In addition, when the liquid storage cavity 10 is positioned below the lower liquid hole 1211 during the reverse pumping, namely, when the liquid storage cavity 10 is positioned below the lower liquid hole 1211, the gas in the liquid storage cavity 10 forms large-diameter bubbles at the part of the lower liquid hole 1211 close to the liquid storage cavity 10, because the lower liquid hole 1211 is a stepped hole, the equivalent diameter of the part of the lower liquid hole 1211 far from the liquid storage cavity 10 is smaller, the bubbles are difficult to enter the part of the lower liquid hole 1211 far from the liquid storage cavity 10, the aerosol generating matrix in the lower liquid hole 1211 can be blocked from flowing to the liquid storage cavity 10, the liquid locking effect is achieved, and the liquid can be supplied to the heating element 13 even if the reverse pumping is realized.

It is understood that the lower liquid hole 1211 is a stepped hole, which means that the lower liquid hole 1211 can be divided into a plurality of sections, each section has the same equivalent diameter, and the equivalent diameters of the different sections are different and tend to increase or decrease along a certain direction. The equivalent diameter of the portion of the liquid trap 1211 close to the liquid storage chamber 10 is larger than the equivalent diameter of the portion of the liquid trap 1211 far from the liquid storage chamber 10, that is, the equivalent diameters of different sections of the liquid trap 1211 decrease in the direction from the liquid storage chamber 10 to the heating element 13. The cross-sectional shapes of different sections of the lower liquid hole 1211 are not limited, and may be regular shapes or irregular shapes, and are specifically designed according to needs.

Specifically, the wall of the lower liquid hole 1211 has at least one step a to form a stepped hole, and the step forms a section of the lower liquid hole 1212. That is, when there is no step A on the wall of the lower liquid hole 1211 along the direction from the liquid storage chamber 10 to the heating element 13, the equivalent diameter is uniform, and at least one step A is formed on the wall of the lower liquid hole 1211, so that the lower liquid hole 1211 forms a stepped hole. The equivalent diameter of the end of the lower liquid hole 1211 close to the liquid storage cavity 10 is larger than that of the sub-lower liquid hole 1212 formed by the step A, and the step A and the end of the lower liquid hole 1211 close to the liquid storage cavity 10 are arranged at intervals, so that the part of the lower liquid hole 1211 close to the liquid storage cavity 10 is an open space, and bubbles can be guided to the liquid storage cavity 10. In the present application, the size of the lower liquid hole section of the lower liquid hole 1211 except the sub lower liquid hole 1212 defined by the step a is the same as the size of the port of the lower liquid hole 1211 close to the liquid storage chamber 10; the step a is a step formed by providing a fin 1213 or a projection 1214, which will be described later, on the wall of the lower liquid passage 1211.

Alternatively, the structural member forming the step a is integrally formed with the top seat 121.

When the hole wall of the lower liquid hole 1211 has a step a, the equivalent diameter of the sub-lower liquid hole 1212 formed by the step a is smaller than the equivalent diameter of the port of the lower liquid hole 1211 close to the liquid storage chamber 10, and the equivalent diameter of the section between the end surface of the step a close to the liquid storage chamber 10 and the port of the lower liquid hole 1211 close to the liquid storage chamber 10 is the same (as shown in fig. 3).

When the walls of the weep holes 1211 have a plurality of steps a, the plurality of steps a form a plurality of sub-weep holes 1212. The equivalent diameters of the sub-weep holes 1212 gradually decrease in the direction from the reservoir chamber 10 toward the heating element 13.

In one embodiment, the equivalent diameter of the lower liquid hole 1211 near the end of the liquid storage chamber 10 is not less than 1mm; it can be understood that when the equivalent diameter of the lower liquid hole 1211 close to the end of the liquid storage cavity 10 is smaller than 1mm, the size is too small to facilitate the liquid discharge, so that the liquid supply speed of the aerosol generating substrate is slow, and the problem that the atomizing amount of the heating element 13 cannot be satisfied exists. Optionally, the equivalent diameter of the lower liquid hole near the end of the liquid storage chamber 10 is 2mm-4mm.

In one embodiment, the equivalent diameter of the sub-bottom weep holes 1212 is 0-2mm; it can be understood that when the user uses the atomizer 1 upside down, the bubbles in the liquid storage chamber 10 tend to flow to the side close to the heating element 13, and since the diameter of the bubbles in the liquid storage chamber 10 is greater than 2mm, the equivalent diameter of the sub liquid discharge hole 1212 is set to be smaller than 2mm, the bubbles in the liquid storage chamber 10 can be prevented from attaching to the surface of the heating element 13 close to the liquid storage chamber 10 through the liquid discharge hole 1211, and the problem of insufficient liquid supply caused by the bubbles can be avoided. Optionally, the equivalent diameter of the sub-weep holes 1212 is 1-1.8mm.

In one embodiment, the equivalent diameter of the end of the lower liquid hole 1211 close to the liquid storage chamber 10 is 0.1mm to 5mm larger than that of the sub-lower liquid hole 1212, so that the portion of the lower liquid hole 1211 close to the liquid storage chamber 10 forms a significant open space. Optionally, the equivalent diameter of the end of the lower liquid hole 1211 close to the liquid storage chamber 10 is 0.2mm to 2mm larger than the equivalent diameter of the sub-lower liquid hole 1212.

Referring to fig. 4 and 5, fig. 4 is a schematic structural view of a first embodiment of a lower fluid hole of the top seat provided in fig. 3, and fig. 5 is a top view of the top seat provided in fig. 4.

In the first embodiment of the lower liquid drainage hole 1211, the hole wall of the lower liquid drainage hole 1211 has a plurality of fins 1213, and the plurality of fins 1213 are provided at intervals in the circumferential direction of the hole wall of the lower liquid drainage hole 1211. The fins 1213 are arranged in a longitudinal direction parallel to the axis of the lower liquid hole 1211. The plurality of fins 1213 cooperate to form at least one step a. It is understood that, since the plurality of fins 1213 are provided at intervals therebetween, the aerosol-generating substrate can flow from the gaps between the fins 1213 to the heat generating body 13; the fins 1213 are provided on the walls of the drainage holes 1211 to increase the drainage area. When the fins 1213 are made of plastic, the contact angle between the fins 1213 and the aerosol-generating substrate is small, and the wettability is good, thereby facilitating the flow of the aerosol-generating substrate to the heating element 13.

Alternatively, the spacing area between two adjacent fins 1213 is smaller than the cross-sectional area of the sub-lower liquid hole 1212. Wherein the cross section means a section perpendicular to the axial direction of the lower liquid hole 1211. With the above arrangement, when the air bubbles occupy the sub-lower liquid orifices 1212, the aerosol-generating substrate can flow to the heat-generating body 13 by the capillary force between the adjacent two fins 1213; that is, the air bubbles are discharged into the reservoir chamber 10 through the sub-lower liquid holes 1212, and the liquid in the reservoir chamber 10 flows to the heat generating body 13 through the gap between the adjacent two fins 1213.

Alternatively, the plurality of fins 1213 are provided at regular intervals along the circumferential direction of the hole wall of the lower liquid hole 1211.

Optionally, the plurality of fins 1213 are disposed at non-uniform intervals along the circumferential direction of the hole wall of the lower liquid hole 1211, and the closer the hole wall of the lower liquid hole 1211 is to the mist outlet 1210, the higher the distribution density of the fins 1213 is, so that the farther the lower liquid hole 1211 is from the mist outlet 1210, the wider the space is, and the directional air bubble removal is achieved by utilizing the characteristic that air bubbles easily flow to the wide space. Since the end of the lower liquid hole 1211 far from the liquid storage chamber 10 is blocked by the bottom wall, the liquid outlet (not shown) of the lower liquid hole 1211 is disposed on the side wall near the mist outlet 1210. By directing the bubbles to the side of the lower liquid hole 1211 far from the mist outlet hole 1210, the aerosol generating substrate can be made to flow to the heating element 13 by the portion of the lower liquid hole 1211 near the mist outlet hole 1210, and the continuous liquid supply and the sufficient liquid supply can be ensured.

Optionally, the end surface of each fin 1213 adjacent to reservoir 10 is planar.

Optionally, the end surface of each fin 1213 close to the liquid storage cavity 10 is a plane, and each fin 1213 and the port of the lower liquid hole 1211 close to the liquid storage cavity 10 are arranged at intervals; the distances between the end surfaces of the fins 1213 close to the liquid storage cavity 10 and the ports of the lower liquid hole 1211 close to the liquid storage cavity 10 are the same; the end face of each fin 1213 away from the hole wall of the lower liquid hole 1211 is a plane; the fins 1213 are matched to form a step A, and the end surfaces of the fins 1213 far away from the wall of the lower liquid hole 1211 are surrounded to form a section of sub-lower liquid hole 1212; the equivalent diameter of the sub-weep hole 1212 is less than the equivalent diameter of the port of the weep hole 1211 adjacent to the reservoir chamber 10 (shown in fig. 4 and 5). Referring to fig. 4, the top ends (the end close to the liquid storage chamber 10) of the plurality of fins 1213 and the port of the lower liquid aperture 1211 close to the liquid storage chamber 10 are spaced, and an open space is provided between the end surface of the fins 1213 close to the liquid storage chamber 10 and the port of the lower liquid aperture 1211 close to the liquid storage chamber 10, so as to guide the air bubbles to the liquid storage chamber 10. The bottom ends of the plurality of fins 1213 may all be disposed directly on the bottom wall of the lower liquid aperture 1211.

Optionally, the end surface of each fin 1213 close to the liquid storage cavity 10 is a plane, and each fin 1213 and the port of the lower liquid hole 1211 close to the liquid storage cavity 10 are arranged at intervals; the distances between the end surfaces of the fins 1213 close to the liquid storage cavity 10 and the ports of the lower liquid hole 1211 close to the liquid storage cavity 10 are the same; the end surface of each fin 1213 away from the hole wall of the lower liquid hole 1211 is a step surface (not shown); the fins 1213 cooperate to form a multi-layer step a, which forms a plurality of sub-lower liquid holes 1212; the equivalent diameter of the plurality of sub-lower liquid holes 1212 gradually decreases in the direction from the reservoir chamber 10 toward the heating element 13.

Optionally, the end surface of each fin 1213 close to the liquid storage cavity 10 is a plane, and each fin 1213 and the port of the lower liquid hole 1211 close to the liquid storage cavity 10 are arranged at intervals. The plurality of fins 1213 include at least one first fin 1213a and at least one second fin 1213b, the distance between the end surface of the first fin 1213a close to the reservoir 10 and the port of the lower liquid hole 1211 close to the reservoir 10 is a first value, the distance between the end surface of the second fin 1213b close to the reservoir 10 and the port of the lower liquid hole 1211 close to the reservoir 10 is a second value, the first value is smaller than the second value, and the first value is greater than zero. A first fin 1213a is arranged on the part of the pore wall of the lower liquid pore 1211 close to the mist outlet 1210, and a second fin 1213b is arranged on the part of the pore wall of the lower liquid pore 1211 far from the mist outlet 1210; that is, the distance between the first fins 1213a and the axis of the mist outlet holes 1210 is smaller than the distance between the second fins 1213b and the axis of the mist outlet holes 1210.

The first fin 1213a comprises a first portion (not shown) and a second portion (not shown) on a side of the first portion remote from the reservoir 10; the end surface of the first part of the first fins 1213a, which is far away from the hole wall of the lower liquid hole 1211, and part of the hole wall of the lower liquid hole 1211 are surrounded to form a section of lower liquid hole 1212; the end surface of the second part of the first fins 1213a far away from the hole wall of the lower liquid hole 1211 and the end surface of the second fin 1213b far away from the hole wall of the lower liquid hole 1211 are surrounded to form another section of sub-lower liquid hole 1212.

Optionally, the end surface of the projection 1214 near the reservoir 10 is flat.

Optionally, the end surface of the protrusion 1214 away from the hole wall of the lower liquid hole 1211 is a step surface (as shown in fig. 8). The bumps 1214 form a plurality of steps A, and the plurality of steps A form a plurality of sub liquid dropping holes 1212; the equivalent diameter of the plurality of sub-lower liquid holes 1212 gradually decreases in the direction from the reservoir chamber 10 toward the heating element 13.

Further, an aerosol-dispersing generating substrate layer B is disposed on a portion of the hole wall of the lower liquid hole 1211 close to the liquid storage chamber 10, that is, the aerosol-dispersing generating substrate layer B does not infiltrate the aerosol-generating substrate. The gas-dispersing aerosol generation substrate layer B is arranged around the whole circumference of the hole wall of the lower liquid hole 1211, so that a liquid film is prevented from being formed at the end, close to the liquid storage cavity 10, of the lower liquid hole 1211 in the liquid discharging process, the discharging is ensured to be smooth, and the problem of insufficient liquid supply is avoided. In addition, in the process of tilting or turning over the atomizer 1, the surface of the aerosol-generating substrate in the lower liquid hole 1211 is more easily disconnected from the surface of the aerosol-generating substrate in the housing 11, so that a continuous liquid film is prevented from being formed between the inner surface of the housing 11 and the port, close to the sub-liquid storage cavity 101, of the hole formed by the surrounding of the lyophobic aerosol-generating substrate layer B, and the surface tension of the liquid film, close to the port of the sub-liquid storage cavity 101, of the hole formed by the surrounding of the lyophobic aerosol-generating substrate layer B can realize the liquid locking function.

It is understood that the aerosol-generating substrate layer B is surrounded to form a shape having an equivalent diameter larger than that of the sub-lower liquid aperture 1212 to form a step a for guiding the bubbles in the lower liquid aperture 1211 to the liquid storage chamber 10.

In this embodiment, the atomizer 1 further includes a sealing member 14, the sealing member 14 is disposed on a side surface of the top seat 121 and a surface of the top seat 121 away from the base 122, and a portion of the sealing member 14 located on the surface of the top seat 121 away from the base 122 extends to a hole wall of the lower liquid hole 1211 to form an aerosol-generating substrate layer a. That is, the sealing member 14 is disposed on the side surface of the atomizing base 12 and the surface of the atomizing base 12 close to the liquid storage chamber 10, and the portion of the sealing member 14 on the surface of the atomizing base 12 close to the liquid storage chamber 10 extends to the hole wall of the lower liquid hole 1211 to form a layer of the aerosol-generating substrate. Optionally, the material of the sealing member 14 is silicone.

Specifically, the sealing member 14 includes a first side wall 141, a top wall 142, and a second side wall 143, the first side wall 141 and the second side wall 143 being located on the same side of the top wall 142; the first sidewall 141 is disposed on the side of the top base 121, the top wall 142 is disposed on the surface of the top base 121 away from the base 122, the second sidewall 143 is disposed on the wall of the lower liquid hole 1211, and the end of the second sidewall 143 contacts or is spaced from the step A, i.e., there is no second sidewall 143 in the sub-lower liquid hole 1212.

Referring to fig. 10 and 11, fig. 10 is a schematic bottom view of a housing of the atomizer shown in fig. 2, and fig. 11 is a schematic bottom view of the atomizer shown in fig. 2.

In this embodiment, the housing 11 has a partition 112 therein, and the partition 112 divides the reservoir chamber 10 into two sub-reservoir chambers 101. Optionally, the spacer 112 is integrally formed with the housing 11. Specifically, the spacer 112 contacts the sealing member 14 to completely separate the two sub-reservoirs 101, forming two sub-reservoirs 101 independent of each other. The two lower liquid holes 1211 are communicated with the two sub liquid storage cavities 101 in a one-to-one correspondence manner, namely, one lower liquid hole 1211 is communicated with one sub liquid storage cavity 101. The heating element 13 is fitted to the top holder 121 to form a heating element liquid-suction chamber 130, and the heating element liquid-suction chamber 130 communicates the two lower liquid-discharge holes 1211. The two sub-liquid storage cavities 101 are respectively a first sub-liquid storage cavity 101 and a second sub-liquid storage cavity 101; the two liquid discharge holes 1211 are respectively a first liquid discharge hole 1211 and a second liquid discharge hole 1211, and the first sub-liquid storage cavity 101, the first liquid discharge hole 1211, the heating element liquid suction cavity 130, the second liquid discharge hole 1211 and the second sub-liquid storage cavity 101 are sequentially connected to form a U-shaped structure; when the nebulizer 1 is inverted, the gas and/or aerosol-generating substrate within the two sub-reservoirs 101 is not in series flow. In other embodiments, the spacer 112 may not be provided, and the inner surface of the housing 11 is tangent to and connected to the outer surface of the mist outlet channel 111, so as to divide the space formed by the housing 11 and the top seat 121 into two sub-liquid storage cavities 101 independent of each other.

Specifically, one end of the top seat 121 close to the bottom seat 122 has a stepped groove (not shown) including a first groove (not shown) close to the lower liquid hole 1211 and a second groove (not shown) far from the lower liquid hole 1211; the size of the second groove is larger than that of the first groove; the heating element 13 is arranged in the second groove and covers the first groove, and the heating element 13 is matched with the first groove to form a heating element liquid suction cavity 130.

Through the arrangement, in the process of tilting or turning over the atomizer 1, the gas in the two sub-liquid storage cavities 10 cannot break through the surface tension of the port of the lower liquid hole 1211 close to the liquid storage cavity 10, and the gas circulation between the two sub-liquid storage cavities 101 cannot be realized. Since the gas flow between the two sub-reservoirs 101 is not realized, the aerosol-generating substrate and the gas in the two sub-reservoirs 101 can only flow in their respective regions, and the whole of them will inevitably receive the resistance of the gas at both sides if it is to flow to one side, therefore, under the surface tension of the port of the lower liquid hole 1211 close to the reservoir 10 and the gas pressure in the two sub-reservoirs 101, the aerosol-generating substrate in the heating element liquid suction chamber 130 can only be retained in the heating element liquid suction chamber 130, and the aerosol-generating substrate in the lower liquid hole 1211 can only be retained in the lower liquid hole 1211, thereby achieving the effect of storing the liquid in the heating element liquid suction chamber 130 and the lower liquid hole 1211 after tilting and inverting, ensuring sufficient liquid supply during the back-suction, and preventing the heating element 13 from being burnt or burned out in a short time.

With continued reference to fig. 2, in this embodiment, the heating element 13 is in the form of a sheet, and the heating element 13 comprises a liquid-conducting base (not shown) and a heating element (not shown), the heating element being disposed on a surface of the liquid-conducting base, the liquid-conducting base being adapted to conduct an aerosol-generating substrate, and the heating element being adapted to atomize the aerosol-generating substrate. The material of the drainage matrix can be porous ceramic or compact material; when the liquid guiding substrate is made of a dense material, the material can be quartz, glass, dense ceramic or silicon. In other embodiments, the heating element 13 may be an existing porous ceramic heating element or a cotton core heating element, and is specifically designed as needed.

This application has still tested the atomizer 1 that adopts the mode of setting of lower liquid hole 1211 that figure 4 and figure 6 provided, the atomizer 1 that this application provided is when invering, the bubble card in the stock solution chamber 10 is close to the port of stock solution chamber 10 in the liquid hole 1211 under, can avoid the bubble to adhere to the surface that the heat-generating body 13 is close to stock solution chamber 10, the problem of the local empty liquid in surface that the heat-generating body 13 is close to stock solution chamber 10 has also been avoided, and the mode of setting of stock solution chamber 10 and the setting of heat-generating body imbibition chamber 130, make and take out at least 8 mouths and can not burn off the heat-generating body 13.

The present application also performed experiments on the liquid locking capability of the U-shaped structure formed by the two sub-liquid storage cavities 101, the two lower liquid holes 1211 and the heat generating body liquid suction cavity 130. Experiments prove that the U-shaped structure has no problem when placed upside down for two days at the longest, and if no strong external force is generated, the liquid cannot collapse, so that the liquid locking capacity is better.

The above embodiments are merely examples and are not intended to limit the scope of the present disclosure, and all modifications, equivalents, and flow charts using the contents of the specification and drawings of the present disclosure or those directly or indirectly applied to other related technical fields are intended to be included in the scope of the present disclosure.
