Fig. 1 is a schematic view of an electronic atomization device according to an embodiment of the present application.

As shown in fig. 1, the electronic atomizing device 100 includes an atomizer 10 and a power supply assembly 20. In one example, the atomizer 10 is not detachable from the power supply assembly 20. In another example, the atomizer 10 is removably connected to the power supply assembly 20, such as an interference fit, a snap fit, or a magnetically attractive connection.

The atomizer 10 is used to atomize a liquid substrate to produce an aerosol.

The power supply assembly 20 includes a battery cell 21 and a circuit 22.

The battery 21 provides electrical power for operating the electronic atomizing device 100. The battery 21 may be a rechargeable battery or a disposable battery.

The circuit 22 may control the overall operation of the electronic atomizing device 100. The circuit 22 controls not only the operation of the battery cell 21 and the ultrasonic atomizing sheet 103, but also the operation of other elements in the electronic atomizing device 100.

It should be noted that, in other examples, the electronic atomizing device 100 may also be a cartridge or an atomizer used in combination with a power supply assembly.

Fig. 2-4 illustrate schematic structural views of an atomizer and protective cover according to an embodiment.

As shown, the atomizer 10 is connected to the protective sheath 20 by a connector 11. The bottom end of the atomizer 10 is provided with an air inlet 102d.

The protective sheath 20 is preferably made of a flexible material, such as silicone. The protective sleeve 20 is assembled at the bottom end of the atomizer 10, and the protective sleeve 20 is provided with a connecting piece 21 which is matched with the connecting piece 11. The connection between the connection piece 11 and the connection piece 21 is preferably a snap connection. The protective sleeve 20 is provided with a boss 22 corresponding to the air inlet 102d. When the protective cover 20 is connected to the atomizer 10, the boss 22 protrudes into the air inlet 102d to form a seal.

Since the protective sleeve 20 seals the air inlet at the bottom of the atomizer 10 (the air outlet at the top of the atomizer 10 can be plugged by a common plug), the problem of leakage caused by volatilization of the liquid matrix in the atomizer 10 and/or air pressure change inside the atomizer 10 due to environmental change can be prevented.

Fig. 5 to 11 show schematic structural views of an atomizer of an embodiment; in the atomizer 10 of this embodiment, it includes:

the main body 101 is substantially flat and cylindrical. The body 101 has longitudinally opposed proximal and distal ends; the proximal end is configured to serve as one end for sucking aerosol by a user, and a suction nozzle opening for sucking by the user is arranged at the proximal end; and the distal end is configured as an end to be coupled with the power supply assembly 20, and the distal end of the main body 101 is open, on which the detachable bottom cover 102 is mounted. After being combined with the bottom cover 102, the body 101 and the bottom cover 102 together define a housing of the atomizer 10, and the interior of the housing is hollow and provided with necessary functional means for storing and atomizing the liquid matrix; through the opening of the main body 101, each necessary functional part can be installed inside the housing of the atomizer 10.

The bottom cover 102 has a first chamber 102a, and the bottom wall of the first chamber 102a has two bosses thereon. The through hole of one of the protruding columns forms a first electrode hole 102b, the conductive part 107a of the first electrode 107 is accommodated in the first electrode hole 102b, and the connecting part 107a of the first electrode 107 is exposed out of the bottom wall; the through hole of the other convex column forms a second electrode hole 102c, the conductive part of the second electrode 108 is accommodated in the second electrode hole 102c, and the connecting part 107 of the second electrode 108 is exposed outside the bottom wall; the heating element 106 may be electrically connected to the power supply assembly 20 via the first electrode 107 and the second electrode 108. A further boss of smaller height is provided intermediate the two bosses, the through-holes of which form an air inlet 102d for external air to enter the atomizer 10 during suction (as indicated by the dashed arrow S1 in the figure). The above-described protrusion prevents the liquid matrix flowing into the first chamber 102a from directly flowing from the through hole to the power module 20.

The interior of the housing is provided with a liquid storage cavity A for storing the liquid matrix, a bracket 103 for sucking the liquid matrix from the liquid storage cavity A, a liquid guide element 104, a liquid guide element 105 and a heating element 106 for atomizing the liquid matrix.

A transmission pipe 101a arranged along the axial direction is arranged in the main body 101, and a liquid storage cavity A for storing liquid matrixes is formed in a space between the outer wall of the transmission pipe 101a and the inner wall of the main body 101; the inner wall of the transmission tube 101a forms an air flow channel, and one end of the transmission tube 101a is communicated with the suction nozzle opening, so that generated aerosol is transmitted to the suction nozzle opening for sucking. In a preferred embodiment, the delivery tube 101a is integrally molded with the body 101 using a moldable material, such that the reservoir A is formed to be open or open distally.

The support 103 is preferably made of a flexible material, i.e., the support 103 is configured as a flexible element, for example, in some examples the support 103 may be made of a silicone, thermoplastic Elastomer (Thermo-Plastic-Elastomer), or thermoplastic Rubber (Thermo-Plastic-Rubber) material.

The bracket 103 includes a first portion 1031 and a second portion 1032 coupled to an upper end face of the first portion 1031.

The first portion 1031 is received in the first chamber 102 a. The first portion 1031 has a second chamber 1031a. The inner side wall of the second chamber 1031a is provided with a bump 1031b, and the bottom end of the transmission tube 101a is abutted with the bump 1031 b; in this way, on the one hand, during assembly, the limit can be performed by the bump 1031 b; on the other hand, the condensed liquid matrix in the transfer tube 101a may be guided toward the liquid guiding element 105 or the heating element 106 by the bump 1031 b. The bottom wall of the second chamber 1031a has a cavity 1031c therein, the cavity 1031c having a vent in fluid communication with the inlet port 102d. Via holes 1031d are further arranged at intervals on two sides of the cavity 1031c, and a penetrable thin wall is arranged in the via holes 1031d, and the via holes 1031d can be plugged through the thin wall.

The second portion 1032 is spaced from the first portion 1031. The upper end of the bottom cover 102 is interposed between the first portion 1031 and the second portion 1032, and the second portion 1032 is held between the inner surface of the main body 101 and the outer surface of the bottom cover 102, thereby achieving sealing. The outer surface of the second portion 1032 has a projection (not shown) by which abutment with the inner surface of the body 101 is facilitated to form a seal.

The liquid guiding member 104 is a layer of lamellar or plate-like organic porous fibers extending in the cross-sectional direction of the main body 101. After assembly, the liquid guiding element 104 is located close to the upper surface of the liquid storage cavity a, opposite to the liquid storage cavity a, and is used for sucking the liquid matrix, and transferring the liquid matrix to the liquid guiding element 105 contacting the lower surface of the liquid storage cavity a, as indicated by arrow R1. The liquid guiding element 104 is provided with a plug hole for the transmission pipe 101a to penetrate.

As will be understood with reference to fig. 6 and 9, in a further implementation, an air compensation channel is further provided between the upper end surface of the first portion 1031 and the lower surface of the liquid guiding element 104, and when the air pressure in the liquid storage cavity a is smaller, the air in the cavity 1031c can flow in through the air compensation channel and the gap between the liquid guiding element 104 and the inner wall of the main body 101, so as to balance the air pressure inside and outside the liquid storage cavity a. In this example, the upper end face of the first portion 1031 has a groove 1031e, and the groove 1031e forms an air compensation passage.

In a preferred embodiment, the fluid transfer element 104 is formed from an organic porous material having elastic properties, exhibiting moderate flexibility and rigidity. In practice, the fluid transfer element 104 has a modulus of elasticity or stiffness that is less than the body 101 or the material defining the fluid storage chamber a, and greater than the material of the fluid transfer element 105. In particular to hard artificial cotton with the Shore hardness of 20-70A. In alternative implementations, the liquid guide element 104 is a hard rayon including oriented polyester fibers, or a hard rayon or rayon made of a filiform polyurethane, or the like. The above liquid guiding element 104 has hardness or flexibility between the usual flexible plant cotton/non-woven fabric (shore hardness less than 20A) and the rigid porous ceramic/microporous metal (shore hardness greater than 80A), so that the structure is stable with extremely low expansion after absorbing and infiltrating the liquid matrix, and the liquid guiding element 104 is kept on the upper end face of the first portion 1031 after assembly and is in contact with the inner wall of the main body 101 or the pipe wall of the transmission pipe 101a between flexible contact and rigid contact, on one hand, it can independently seal the liquid storage cavity a by utilizing its own flexibility, and on the other hand, it has a certain hardness and can be easily fixed and maintained. In particular, as shown in the above figures, the shape of the liquid guiding element 104 is substantially adapted to the opening at the lower end of the liquid storage chamber a, and thus can be used to cover, seal and seal the liquid storage chamber a. In a more preferred implementation, the fluid transfer element 104 has a shore hardness of 50-70A, approximately equivalent to a thermoplastic elastomer or silicone.

The liquid guiding element 104 has a substantially elliptical shape, and the insertion hole of the transmission tube 101a has an elliptical shape. The liquid guiding element 104 is made of oriented fibers such as polyethylene and/or polypropylene which are oriented and arranged along the length direction, and the oriented fibers are arranged along the length direction of the liquid guiding element 104 so as to enable the liquid guiding element 104 to have the characteristic of strong bending resistance and further hard. And the liquid guide element 104 prepared by the organic fiber can keep sufficient gaps among fiber materials in the preparation process, so that the liquid matrix can be transferred, and the liquid guide element 104 can have proper flexibility. The liquid guiding member 104 having the above oriented fibers is anisotropic. In particular, the flexural strength of the material is at least greater along the length direction than along the width direction; or in another aspect, has a liquid transfer rate in the length direction that is greater than a liquid transfer rate in the width direction.

The surface or interior of the liquid guide 104 may have a texture extending in the length direction; specifically, the grain is prepared from the above oriented fibers by a textile process such as roller pressing, and the spacing between parts of the fibers is increased by the roller pressing or the hydroentangling process, so that macroscopic dents are formed at the positions where the spacing is increased, and the width is less than 1mm and is about 0.1-0.5 mm; further, the dimples may be textured on the surface or inside of the liquid guide 104, which may be advantageous for the transfer and retention of the liquid matrix and for improving the rigidity.

The liquid guiding element 105 is made of a flexible fibrous material, such as cotton fibers, nonwoven fibers, sponge, etc.; the liquid guiding element 105 is in the form of a sheet or plate extending in the longitudinal direction of the main body 101, i.e. is arranged substantially perpendicular to the liquid guiding element 104. The liquid-guiding member 105 is configured in a deformed shape (substantially a bilateral symmetry structure) including a body 1051 extending in the width direction of the main body 101, and extension portions 1052 extending from both end sides of the body 1051 in the longitudinal direction of the main body 101 toward the liquid storage chamber a. In use, the body 1051 is received or held in the second chamber 1031a, with a gap maintained between the front and rear surfaces of the body 1051 and the inner side walls of the second chamber 1031 a; the extension 1052 contacts the lower surface of the liquid guide member 104 to draw the liquid matrix from the liquid guide member 104 and then transfer it to the body 1051 by capillary infiltration.

The heating element 106 may be initially formed from a substrate material that is then cut and/or stamped into the appropriate shape by various mechanical processes, including but not limited to stamping, laser cutting, photolithography, chemical etching, and the like. The substrate material may be made of a conductive metal suitable for resistive heating. In some embodiments, the substrate material comprises nichrome, nickel alloy, stainless steel, or the like.

The heating element 106 includes a heating portion 1061, a connecting portion 1062, a conductive portion 1063, and a conductive portion 1064.

The heating portion 1061 has a plurality of heating tracks connected in series and/or parallel, and the shape of the heating track is not limited herein. A part of the heating portion 1061 is bent to contact the front surface of the body 1051, another part is bent to contact the rear surface of the body 1051, and the non-bent part of the heating portion 1061 contacts the bottom surface of the body 1051. As can be seen from the figure, the above-mentioned part of the heating portion 1061 and the other part of the heating portion 1061 are bent toward each other and maintain a certain gap with each other after bending, the gap is typically between 1mm and 2mm, and in a specific example, the gap may be 1.2mm or 1.5mm. The folded heating portion 1061 resembles a plurality of spaced tines of a rake nail. Thus, by the above-described structural design, the body 1051 can be held or fixed in the heating portion 1061, facilitating the assembly of the liquid guiding element 105 and the heating element 106 together to the bracket 103.

Both ends of the heating portion 1061 have connection portions 1062. Similar to the heating portion 1061, the connection portion 1062 may be partially bent and maintain a gap, and the other portion may not be bent.

The conductive portion 1063 serves to guide current. The conductive parts 1063 are configured to extend in the length direction of the main body 101, one end of the conductive part 1063 is connected to one of the connection parts 1062, and the other end extends toward the bottom cover 102; the conductive portion 1064 is configured to extend in the longitudinal direction of the main body 101, one end of the conductive portion 1064 is connected to another connection portion 1062, and the other end extends toward the bottom cover 102.

When the liquid guiding element 105 and the heating element 106 are assembled to the holder 103, the other end of the conductive portion 1063 may pierce the thin wall of the via 1031d and remain in the first electrode hole 102b after passing through the via 1031d, so that contact may be maintained with the conductive portion 107a of the first electrode 107 to form an electrical connection. The other end of the conductive portion 1064 is similar. In further implementations, the conductive portion 1063 has a protruding portion 1063a, the protruding portion 1063a facilitating contact with the conductive portion 107a of the first electrode 107; the conductive portion 1064 may also be provided as such.

When the liquid guiding element 105 and the heating element 106 are assembled to the bracket 103, the non-bent portion of the heating portion 1061 is located above the cavity 1031c, and a gap is maintained between the bent portion of the heating portion 1061 and the inner side wall of the second chamber 1031 a; in this way, the heating portion 1061 heats the atomized aerosol to be released in the cavity 1031c and the gap; the air flowing from the vent hole of the cavity 1031c may flow toward the transfer tube 101a together with the aerosol from the gap between the front and rear surfaces of the body 1051 and the side wall of the second chamber 1031a, and may join at the gap between the body 1051 and the end of the transfer tube 101a before flowing into the transfer tube 101 a.

When the liquid guiding element 105 and the heating element 106 are assembled to the holder 103, the connection portion 1062 spans between the cavity 1031c and the via 1031d. The connection portion 1062 may be configured to operate at a lower temperature than the heating portion 1061. For example: when the connection portion 1062 and the heating portion 1061 are connected in series between the conductive portion 1063 and the conductive portion 1064, a resistance value of the connection portion 1062 may be smaller than a resistance value of the heating portion 1061; if connected in parallel, the other way around.

Fig. 12 to 13 show schematic structural views of a nebulizer of another embodiment; unlike the examples of fig. 5 to 11, the following are:

the holder 103 includes only the second portion 1032 and a portion (corresponding to an end face of the upper end of the first portion 1031 in the example of fig. 5 to 11) provided between the lower surface of the liquid guiding member 104 and the upper end of the bottom cover 102.

In the bottom cover 102, a holding portion 102e is provided in the first chamber 102a, and the liquid guiding member 105 is held in the first chamber 102a by the holding portion 102 e. The holding portion 102e includes a projection protruding from a side wall of the first chamber 102 a. The connection portion 1062 of the heating element 106 is held in contact with the holding portion 102 e. The air flowing in from the air inlet 102d may flow toward the transfer tube 101a from a gap between the front and rear surfaces of the body 1051 and the side wall of the first chamber 102a together with the aerosol.

The bottom end of the transfer tube 101a is disposed adjacent to the liquid guiding element 105, preferably in contact with the extension 1052 of the liquid guiding element 105; in this way, the condensed liquid matrix in the transfer tube 101a can be directed towards the liquid guiding element 105. In a preferred implementation, the inside of extension 1052 has an inclined surface by which contact with liquid guiding element 105 is facilitated.

It should be noted that the description and drawings of the present application show preferred embodiments of the present application, but the present application may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, which are not to be construed as additional limitations on the content of the present application, but are provided for the purpose of providing a more thorough understanding of the present disclosure. The above-described features are further combined with each other to form various embodiments not listed above, and are considered to be the scope described in the present specification; further, modifications and variations of the present utility model may occur to those skilled in the art in light of the foregoing teachings, and all such modifications and variations are intended to be within the scope of the appended claims.
