Referring to fig. 2 and 3, fig. 2 is a schematic structural diagram of a first embodiment of an atomizer provided in the present application, 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 an installation cavity 120, and the installation cavity 120 is used for installing the heating body 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 lower liquid groove 1211, the side wall of the lower liquid groove 1211 is provided with an opening 1211a communicated with the mounting cavity 120, the heating element 13 is communicated with the liquid storage cavity 10 through the lower liquid groove 1211 and the opening 1211a, 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 channel 111, the top seat 121 is provided with a mist outlet hole 1210, the mist outlet hole 1210 communicates the mist outlet channel 111 with the mounting cavity 120, that is, the mist outlet hole 1210 communicates the mist outlet channel 111 with the atomizing cavity; 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 hole 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 only describes the atomizing base 12 formed by the top base 121 and the bottom base 122 in detail as an example.

In one embodiment, the top seat 121 is provided with two lower liquid grooves 1211 respectively located at two sides of the mist outlet 1210. An opening 1211a is disposed on a side wall of the lower liquid tank 1211 close to the mist outlet 1210, and the opening 1211a is disposed on a side wall of the lower liquid tank 1211 close to a bottom wall of the lower liquid tank 1211, so that the aerosol-generating substrate in the lower liquid tank 1211 is outputted to the opening 1211a as far as possible when the atomizer 1 is in normal use (the liquid storage chamber 10 is located above the heating element 13).

In the embodiment of the present application, the lower liquid tank 1211 has a guiding structure, and the guiding structure gradually increases the space of the lower liquid tank 1211 along the direction away from the opening 1211a, so as to guide the bubbles toward the direction away from the opening 1211a, and push the aerosol-generating substrate in the lower liquid tank 1211 toward the direction close to the opening 1211a, thereby ensuring sufficient liquid supply, and avoiding the dry burning of the heating element 13.

It can be understood that when the atomizer 1 is in normal use (the liquid storage chamber 10 is located above the heating element 13), bubbles enter the liquid absorption surface of the heating element 13 from the atomization surface of the heating element 13 during atomization; the atomization surface of the heating element 13 is the surface of the heating element 13 far away from the liquid storage cavity 10, the liquid absorption surface of the heating element 13 is the surface of the heating element 13 directly contacting with the aerosol generating substrate, and the surface of the heating element 13 close to the liquid storage cavity 10 directly contacts with the aerosol generating substrate, namely, the surface of the heating element 13 close to the liquid storage cavity 10 is the liquid absorption surface, and the aerosol generating substrate is guided to the atomization surface from the liquid absorption surface by the capillary force of the capillary holes of the heating element 13. When the liquid storage cavity 10 is filled for the first time or the atomizer 1 is turned upside down (the heating element 13 is positioned above the liquid storage cavity 10) for a period of time, bubbles can also exist on the surface of the heating element 13 close to the liquid storage cavity 10. The bubbles are attached to the surface of the heating element 13 close to the liquid storage cavity 10, which may block the port of the capillary hole of the heating element 13, thereby reducing the liquid supply amount from the liquid storage cavity 10 to the heating element 13, and further causing insufficient liquid supply to cause dry burning of the heating element 13. By providing the guiding structure in the lower liquid groove 1211, the air bubbles near the surface of the liquid storage chamber 10 of the heating element 13 are guided away from the opening 1211a by utilizing the characteristic that the air bubbles flow to the open space, and the aerosol generating substrate in the lower liquid groove 1211 is pressed towards the opening 1211a, so that the aerosol generating substrate can enter the heating element 13 through the opening 1211a, namely, the aerosol generating substrate can still flow to the heating element 13 by the part of the lower liquid groove 1211 near the opening 1211a, and the continuous liquid supply and the sufficient liquid supply are ensured.

In the present embodiment, the inner surface of the lower liquid groove 1211 has a plurality of fins 1212, the plurality of fins 1212 are provided at intervals along the circumferential direction of the inner surface of the lower liquid groove 1211, and the longitudinal direction of the fins 1212 is provided in parallel with the depth direction of the lower liquid groove 1211 (i.e., the axial direction of the atomizer 1). The plurality of fins 1212 cooperate to form the guide structure described above.

Note that, since the plurality of fins 1212 are provided at intervals, the aerosol-generating substrate can flow from the gaps between the fins 1212 to the heating body 13; the plurality of fins 1212 cooperate to guide the bubbles of air to the side away from the opening 1211a in the width direction of the atomizer 1 while the aerosol-generating substrate still flows from the gaps between the fins 1212 to the opening 1211a near the side of the opening 1211a, and enters the heat-generating body 13. The plurality of fins 1212 are arranged on the inner surface of the lower liquid tank 1211, and the equivalent diameter of the space formed by the plurality of fins 1212 in cooperation with the surrounding is smaller than the equivalent diameter of the port of the lower liquid tank 1211, which is close to the liquid storage cavity 10, so that the bubbles are easy to separate from the lower liquid tank 1211 and enter the liquid storage cavity 10 due to the characteristic that the bubbles are easy to flow to the open space, the insufficient liquid supply caused by the bubbles is avoided, and the risk of burning or burning off the heating body 13 is reduced. In addition, when the liquid storage cavity 10 is positioned below the lower liquid groove 1211, the gas in the liquid storage cavity 10 forms large-diameter bubbles at the part of the lower liquid groove 1211 close to the liquid storage cavity 10, and because the equivalent diameter of the end of the lower liquid groove 1211 close to the liquid storage cavity 10 is smaller than the equivalent diameter of the space formed by the plurality of fins 1212 in a matching and enclosing manner, the bubbles are difficult to enter the part of the lower liquid groove 1211 far from the liquid storage cavity 10, so that the aerosol generating matrix in the lower liquid groove 1211 can be prevented from flowing to the liquid storage cavity 10, the liquid locking effect is achieved, the liquid can be supplied to the heating body 13 even if a certain number of ports are reversely pumped, and the dry burning is prevented.

Specifically, the plurality of fins 1212 includes at least one first fin 1212a and at least one second fin 1212b, a distance between an end surface of the first fin 1212a close to the reservoir 10 and a port of the lower liquid groove 1211 close to the reservoir 10 is a first value, a distance between an end surface of the second fin 1212b close to the reservoir 10 and a port of the lower liquid groove 1211 close to the reservoir 10 is a second value, and the first value is smaller than the second value. The first fin 1212a is located near the opening 1211a, and the second fin 1212b is located away from the opening 1211a. The bottom ends of the plurality of fins 1212 may all be disposed directly on the bottom wall of the lower liquid tank 1211.

The first fins 1212a and the second fins 1212b are arranged at intervals; when the number of the first fins 1212a is plural, the plural first fins 1212a are provided at intervals; when the number of the second fins 1212b is plural, the plural second fins 1212b are provided at intervals.

Optionally, the end of each fin 1212 adjacent to the reservoir 10 is planar (as shown in fig. 3). By providing the longer first fin 1212a and the shorter second fin 1212b of each fin 1212 close to the opening 1211a and far from the opening 1211a, an opposite open space is formed at a side of the second fin 1212b close to the liquid storage chamber 10 in a direction far from the opening 1211a.

Optionally, the end surface of the second fin 1212b near the liquid storage cavity 10 is a slope, the slope includes a first end (not shown) and a second end (not shown), a distance between the first end of the slope and the port of the lower liquid groove 1211 near the liquid storage cavity 10 is smaller than a distance between the second end of the slope and the port of the lower liquid groove 1211 near the liquid storage cavity 10, and the first end of the slope contacts with an inner surface of the lower liquid groove 1211 (as shown in fig. 4, fig. 4 is a schematic structural view of another embodiment of the fin of the top seat provided in fig. 3). The end face of the second fin 1212b close to the liquid storage cavity 10 is set to be the inclined face, the end face close to the liquid storage cavity 10 is a plane relative to the second fin 1212b, a wider space is formed on one side of the second fin 1212b close to the liquid storage cavity 10, and a better bubble guiding effect is achieved. At this time, the end surface of the first fin 1212a near the reservoir chamber 10 may be a plane or an inclined surface, and is specifically designed according to the requirement; when the end surface of the first fin 1212a close to the liquid storage cavity 10 is a slope, the slope includes a third end (not shown) and a fourth end (not shown), a distance between the third end of the slope and the end of the lower liquid groove 1211 close to the liquid storage cavity 10 is smaller than a distance between the fourth end of the slope and the end of the lower liquid groove 1211 close to the liquid storage cavity 10, and the third end of the slope contacts with an inner surface of the lower liquid groove 1211, so that a wider space is formed on one side of the first fin 1212a and the second fin 1212b close to the liquid storage cavity 10, which is beneficial to guiding bubbles to the direction of the liquid storage cavity 10. It can be understood that the inclined plane may be a plane, a curved surface, or a stepped surface, and is specifically designed according to the needs.

Alternatively, the first value is greater than zero, i.e., the distance between the end of the first fin 1212a proximate the reservoir 10 and the end of the lower trough 1211 proximate the reservoir 10 is greater than zero (as shown in FIG. 3). By making the first value larger than zero, the lower liquid groove 1211 may be divided into two parts, the inner surface of the first part of the lower liquid groove 1211 is not provided with the fins 1212, and the inner surface of the second part of the lower liquid groove 1211 is provided with the fins 1212, the first part being located at a side of the second part close to the liquid storage chamber 10; since the first portion of the lower liquid tank 1211 is not provided with the fins 1212, the space of the first portion of the lower liquid tank 1211 is wider than the space of the second portion of the lower liquid tank 1211, that is, the lower liquid tank 1211 is in the direction close to the liquid storage chamber 10, and the space becomes wider, which is advantageous for guiding the bubbles toward the liquid storage chamber 10.

Optionally, an end surface of each fin 1212, which is away from the inner surface of the liquid dropping groove 1211, is a plane (as shown in fig. 3), so that the manufacturing difficulty of the fin 1212 is reduced on the premise that the liquid locking of the atomizer 1 in an inverted manner can be achieved.

Optionally, the fins 1212 and the top base 121 are integrally formed, so that the assembly difficulty is reduced.

Alternatively, a plurality of fins 1212 are provided at regular intervals along the circumferential direction of the inner surface of the lower liquid sumps 1211.

Alternatively, the distribution density of the fins 1212 increases in a direction toward the opening 1211a, so that the farther from the opening 1211a the lower liquid groove 1211 is, the wider the space is, and the directional removal of the bubbles is achieved by utilizing the characteristic that the bubbles easily flow to the wide space.

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 includes a liquid-guiding substrate (not shown) and a heating element (not shown), the heating element is disposed on a surface of the liquid-guiding substrate, the liquid-guiding substrate is used for guiding the aerosol-generating substrate, and the heating element is used for atomizing 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.

The atomizer 1 further comprises a sealing member 14, and the sealing member 14 is disposed on the end surface of the top seat 121 far away from the base 122 and the side surface of the top seat 121 to realize sealing and avoid liquid leakage.

Referring to fig. 5 and 2, in this embodiment, a partition 112 is provided inside the housing 11, and the partition 112 divides the reservoir chamber 10 into two sub-reservoir chambers 101 independent of each other. Optionally, the spacer 112 is integrally formed with the housing 11. Specifically, the spacer 112 is in contact with the sealing member 14 to completely separate the two sub-reservoirs 101. Two lower liquid grooves 1211 are communicated with the two sub liquid storage cavities 101 in a one-to-one correspondence manner, namely, one lower liquid groove 1211 is communicated with one sub liquid storage cavity 101. The heating element 13 is matched with the top seat 121 to form a heating element liquid suction cavity 130, and the heating element liquid suction cavity 130 is communicated with the two lower liquid grooves 1211; the heat-generating body liquid-sucking chamber 130 communicates with the lower liquid tank 1211 through an opening 1211a. The two sub-liquid storage cavities 101, the two lower liquid grooves 1211 and the heat generating body liquid suction cavity 130 form a U-shaped structure. Specifically, the two sub-liquid storage cavities 101 are a first sub-liquid storage cavity 101 and a second sub-liquid storage cavity 101 respectively; the two lower liquid grooves 1211 are respectively a first lower liquid groove 1211 and a second lower liquid groove 1211, and the first sub liquid storage cavity 101, the first lower liquid groove 1211, the heating element liquid suction cavity 130, the second lower liquid groove 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 the present embodiment, the two spacers 112 are arranged coplanar and the plane of the two spacers 112 is perpendicular to the width direction of the atomizer 1. In other embodiments, the partition 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, a first groove 1213 (as shown in fig. 3) is formed on a side of the top seat 121 close to the base 122, a second groove 1221 is formed on a side of the base 122 close to the top seat 121 (as shown in fig. 7, fig. 7 is a structural schematic diagram of the base of the atomizer provided in fig. 2), and the first groove 1213 and the second groove 1221 form the installation cavity 120 (as shown in fig. 2). The heating element 13 is arranged in the first groove 1213, and a heating element liquid suction cavity 130 is formed between the bottom wall of the first groove 1213 and the heating element 13; specifically, the first groove 1213 is a stepped groove including a first sub-groove (not shown) close to the lower liquid groove 1211 and a second sub-groove (not shown) far from the lower liquid groove 1211; the size of the second subslot is larger than that of the first subslot; the heating element 13 is arranged in the second sub-groove and covers the first sub-groove, and the heating element 13 is matched with the first sub-groove to form a heating element liquid suction cavity 130.

Since the two sub-reservoirs 101 cannot communicate with each other, the aerosol-generating substrate and the gas in the two sub-reservoirs 101 can flow only in their respective regions, and the whole of the aerosol-generating substrate and the gas must be subjected to resistance by the gas on both sides if the aerosol-generating substrate and the gas flow to one side of the two sub-reservoirs 101, the aerosol-generating substrate in the heating element liquid-suction chamber 130 can only stay in the heating element liquid-suction chamber 130 and the aerosol-generating substrate in the lower reservoir 1211 can only stay in the lower reservoir 1211 due to the surface tension of the end of the lower reservoir 1211 close to the liquid-storage chamber 10 and the gas pressure in the two sub-reservoirs 101, so that the effect of storing the aerosol-generating substrate in the heating element liquid-suction chamber 130 and the lower reservoir 1211 after tilting and inverting can be achieved, sufficient liquid supply during the back-suction can be ensured, and the phenomenon of burning or burnout of the heating element 13 can not occur in a short time. That is, by forming the liquid suction chamber 130 of the heating element, the atomizer 1 can be suitable for suction in various directions, and the phenomenon that the heating element 13 is empty on the side close to the liquid storage chamber 10 is avoided.

It can be understood that the guiding structure formed by the plurality of fins 1212 has a certain liquid locking function, and the liquid suction cavity 130 of the heating element is further configured to enhance the liquid locking function, so as to ensure that sufficient liquid supply is provided when a user lies or lifts up for suction.

This application has still tested the atomizer 1 that adopts fig. 2 to provide, the atomizer 1 that this application provided is when invering, bubble in the stock solution chamber 10 removes to the direction that is close to heat-generating body 13, bubble card 1211 is close to the port of stock solution chamber 10 at lower cistern in the stock solution chamber 10, can avoid the bubble to attach to the surface that heat-generating body 13 is close to stock solution chamber 10, the problem of the local empty liquid in surface that heat-generating body 13 is close to stock solution chamber 10 has just also been avoided, and the setting mode of stock solution chamber 10 and the setting of heat-generating body imbibition chamber 130, make to pour out at least 8 mouths and can not burn off heat-generating body 13.

The liquid locking capacity that two sub-liquid storage cavities 101, two lower liquid grooves 1211 and the heat-generating body liquid suction cavity 130 form the U-shaped structure is tested, and the test proves that the U-shaped structure is inverted for two days without any problem, and if no strong external force vibrates, the liquid cannot be collapsed, so that the liquid locking capacity is better.

In other embodiments, the spacer 112 is not disposed in the housing 11, and the liquid storage chamber 10 is disposed around the mist outlet passage 111; the plurality of fins 1212 have a liquid locking function to ensure sufficient liquid supply for short-time back-pumping.

Referring to fig. 8 and 9, fig. 8 is a schematic structural diagram of a second embodiment of an atomizer provided in the present application, and fig. 9 is a schematic structural diagram of the atomizer provided in fig. 8 in an inverted state.

The second embodiment of the present application provides an atomizer having substantially the same structure as the atomizer provided in the first embodiment of the present application, except that: the specific arrangement of the guide structure of the lower liquid tank 1211 is different, and other structures are basically the same and will not be described again.

In this embodiment, the inner surface of the bottom wall of the lower liquid tank 1211 is an inclined surface 1211b, and the inclined surface 1211b forms the above-mentioned guiding structure; the inclined surface 1211b is inclined in a direction away from the liquid storage chamber 10 in a direction away from the opening 1211a. Specifically, the inclined surface 1211b is a plane, a curved surface or a step surface, and only needs to be inclined in a direction away from the opening 1211a and away from the liquid storage chamber 10.

In this embodiment, the two sub-liquid storage chambers 101, the two lower liquid grooves 1211, and the heat generating body liquid suction chamber 130 form a U-shaped structure.

When the atomizer 1 is used normally, the liquid storage chamber 10 is located above the heating element 13, the air bubbles near the surface of the liquid storage chamber 10 of the heating element 13 enter the liquid trap 1211 through the opening 1211a, the inner surface of the bottom wall of the liquid trap 1211 is provided with a slope 1211b to guide the air bubbles to the direction far away from the opening 1211a, and the aerosol-generating substrate in the liquid trap 1211 is pressed to the direction near the opening 1211a, so that the aerosol-generating substrate still left in the liquid trap 1211 near the opening 1211a can enter the heating element 13 through the opening 1211a. When the atomizer 1 is inverted (as shown in fig. 9, the arrows in fig. 9 indicate the flow direction of the aerosol-generating substrate, and the dashed line enclosed figure indicates the bubbles), the heating element 13 is located above the liquid storage chamber 10, the bubbles in the liquid storage chamber 10 move toward the heating element 13, and since the inner surface of the bottom wall of the liquid trap 1211 is set as the inclined surface 1211b, the bubbles are located on the side of the bottom wall of the liquid trap 1211 away from the opening 1211a, so as to prevent the bubbles from entering the opening 1211a, and the bubbles are blocked in the liquid trap 1211, thereby preventing the aerosol-generating substrate in the liquid suction chamber 130 of the heating element from flowing out to some extent.

The above are only embodiments of the present application, and not intended to limit the scope of the present application, and all equivalent structures or equivalent processes performed by the present application and the contents of the attached drawings, which are directly or indirectly applied to other related technical fields, are also included in the scope of the present application.
