Furthermore, the technical features mentioned in the different embodiments of the utility model described below can be combined with each other as long as they do not conflict with each other.

Referring to fig. 1 to 4, a perspective assembly diagram and a perspective disassembly diagram of an atomizer 100 according to a first embodiment of the present invention are shown. The atomizer 100 is configured to atomize a liquid substrate to generate an aerosol, and may include a support 10, a capillary element 20, a heat generating member 30, and a securing structure 40. The support 10 is used for accommodating and supporting the capillary element 20, and the fixing structure 40 is used for fixing the heat generating member 30 to be closely attached to the capillary element 20. The atomizer 100 may further include a housing (see housing 50 in fig. 21) defining a reservoir for storing the liquid matrix, from which the liquid matrix is delivered to the capillary element 20 to enable continuous atomization. The reservoir is a space defined within the housing. The liquid matrix can be liquid such as tobacco tar, medicinal liquid, etc.; herein, a liquid substrate may also be referred to as a liquid, an aerosol may also be referred to as a vapor, and an aerosol may also be referred to as a smoke, an aerosol, or an aerosol. The shell can also provide a suction opening, and a smoke exhaust pipe can be arranged in the shell; the smoke exhaust pipe defines a hollow duct for passing therethrough the aerosol formed on the atomizing surface of the capillary element and being discharged through the suction nozzle portion.

Wherein the bracket 10 defines an accommodating space 11. The receiving space 11 may comprise a support main face and at least one stop side face. For example, the housing space 11 may comprise a support main face and two stop side faces on either side of the support main face, so as to be able to receive and position the capillary element 20. The stent 10 may be a single member or a combination of two or more members. The holder 10 may comprise two support blocks 14 on each side of the receiving space 11, the side of each support block 14 facing the receiving space 11 serving as a stop side between which the main support surface is connected.

The capillary element 20 is disposed in the accommodating space 11 and includes a liquid suction surface 21 and an atomization surface 22, and the atomization surface 22 is exposed to an opening of the accommodating space 11. The capillary element 20 may be made of a material having capillary channels or pores, such as a fiber cotton, a porous ceramic body, a glass fiber rope, a porous glass ceramic, a porous glass, etc., of a capillary structure. The atomising surface 22 may be the side of the capillary element 20 facing away from the major supporting surface of the holder 10, and the wicking surface 21 may be the side opposite to the atomising surface 22; the wicking surface 21 may also include other peripheral sides of the capillary element 20 in addition to the atomization surface 22. The liquid-absorbing surface 21 may communicate with the reservoir chamber via a liquid channel for absorbing the liquid substrate, which is transported in a capillary channel in the capillary element 20 to the atomizing surface 22.

The heat generating member 30 is disposed close to the atomizing surface 22 of the capillary element 20, and includes two electrode connection terminals 32 and a heat generating portion 31 extending between the two electrode connection terminals 32. The heating element 30 is disposed on the atomizing surface 22 side of the capillary element 20, and the fixing structure 40 is used to make the heating element 30 adhere to the atomizing surface 22 as closely as possible. The heat generating member 30 may further include two electrode connection terminals 32, and the heat generating portion 31 is located between the two electrode connection terminals 32. The heat generating portion 31 may be a current line structure that supplies heat by a resistance heat generation method. Since the cross-sectional size of the current path structure in the heat generating portion 31 is small due to resistance heating, the strength of the structure is not high, and the fixing structure 40 is required to prevent deformation and increase the degree of adhesion to the capillary element 20. The electrode connection end 32 may be in the form of a contact piece having a large contact area for making electrical contact with an electrode post for making electrical contact with, for example, an electrode pogo pin in a power module; the supporting block 14 is used to support the electrode connecting end 32.

The fixing structure 40 is used to fix the heat generating component 30 on the bracket 10, so that at least part of the heat generating component 31 covers the opening of the accommodating space 11 and is attached to the atomizing surface 22. The fixing structure 40 may be any structure capable of fixing and/or pressing a part or all of the heat generating member 30 to improve the adhesion between the heat generating portion 31 and the atomizing surface 22. For example, a plurality of studs 41 may be initially preformed on the support block 14, and the studs 41 may be heat-staked and cooled to anchor the electrode connection end 32 to the support block 14. For example, after the capillary element 20 is placed in the receiving space 11 and the electrode connection end 32 is rested on the supporting block 14, the column 41 may be heated to be melted by a hot press, and a portion of the column 41 is deformed to be re-solidified to press the electrode connection end 32 on the supporting block 14. In some examples, the number of posts 41 may be four, which may be pre-formed integrally with the stent 10 and distributed at the four corners of the stent 10. The electrode connecting end 32 may be provided with a through hole for the column 41 to be inserted into, or a right-angled or semicircular groove capable of being in limit fit with the column 41 may be formed at the edge; in this way, the post 41 can fix the heat generating member 30 to the bracket 10 after being thermally melted.

In the atomizer 100 of this embodiment, the heat generating member 30 is disposed close to the atomizing surface 22 of the capillary element 20, and the heat generating member 30 is fixed to the holder 10 by the fixing structure 40, so that the heat generating portion 31 can be attached to the atomizing surface 22. In this way, the shape of the heat generating member 30 can be maintained and easily attached to the heat generating portion 31, so that the atomizing surface 22 can be heated uniformly, thereby improving the atomizing effect and reducing the occurrence of oil frying during use.

In an alternative embodiment, as shown in fig. 1 to 4, at least a portion of the fixing structure 40 extends along the extending direction of the heat generating portion 31 and presses against a portion of the surface of the heat generating portion 31, so as to attach the heat generating portion 31 to the atomizing surface. For example, the fixing structure 40 may further include an annular pressing piece 42, and the annular pressing piece 42 may press the heat generating portion 31 against the atomizing surface 22. The heat generating portion 31 may be in the form of a plate, and two sides thereof may be provided with a plurality of comb-shaped structures 35, and these comb-shaped structures 35 may not form a current path, so that the temperature is not too high when the atomizer 100 is powered on; the annular pressing sheet 42 can be attached to the comb-shaped structures 35, and the annular pressing sheet 42 can be pressed by the electrode posts, so that the comb-shaped structures 35 are pressed on the atomizing surface 22, and the comb-shaped structures 35 drive the heating part 31 to be pressed on the atomizing surface 22. The annular pressing piece 42 can be made of high temperature resistant plastic, and both ends thereof can be pressed against the electrode connecting ends 32, and the other parts thereof can be pressed against the comb-teeth structures 35. In other embodiments, the annular pressing piece 42 may be directly pressed on the edge portion of the heat generating portion 31 as long as the melting point of the annular pressing piece 42 is higher than the operating temperature of the heat generating portion 31. In this way, the heat generating portion 31 can be further assisted to be entirely pressed against the atomizing surface 22, increasing the degree of adhesion of the heat generating portion 31 to the atomizing surface 22.

In an alternative embodiment, as shown in fig. 1 to 4, the bracket 10 may include a bracket body 10A and a sealing member 10B, the bracket body 10A including the receiving space 11 and the supporting block 14; the seal 10B receives the holder body 10A and is adapted to sealingly engage a housing defining a reservoir chamber such that the liquid substrate is delivered only to the suction surface 21 of the capillary element 20 and does not leak through the interface between the holder 10 and the housing. The stent body 10A may be made of a hard plastic and the seal 10B may be made of a flexible material such as silicone or thermoplastic elastomer (TPE). In this manner, it is possible to facilitate the accommodation of the capillary element 20, the fixing of the heat generating member 30, and the sealing engagement of the holder 10 with the housing.

In an alternative embodiment, as shown in connection with fig. 1-4, a suitable capillary element 20 may be a fibrous material or a porous material having a microporous structure, which may be in the form of a flat plate. In some preferred examples, the capillary element 20 is made of a flexible material, and the flexible capillary element 20 has a certain elasticity in contraction, which is beneficial to improve the surface fitting degree of the rigid heat generating member 30 when the flexible capillary element is in contact with the rigid heat generating member. For example, the capillary element 20 may be made of cellucotton and may have a square plate shape; the flat atomizing surface 22 provided by the flat plate shape can be easily attached to the sheet-shaped heat generating member 30. Accordingly, the heat generating member 30 may be a sheet-shaped body, and the heat generating portion 31 thereof may include at least one of a mesh-shaped line structure and a meander-shaped line structure. In the mesh wire structure, a plurality of closed pores may be included, such that the mesh wire structure includes parallel wires; in a meander line structure, repeating lines such as S-shaped, Z-shaped, U-shaped, etc. may be included, which may be arranged in series. The heat generating portion 31 may also include both a mesh wiring structure and a meander wiring structure so as to have a series and parallel wiring structure. In this way, the heat generating portion 31 can be pressed integrally against the surface of the liquid-permeable cotton, and the heat generating portion 31 can be brought into closer contact with the liquid-permeable cotton by compressing the liquid-permeable cotton to some extent.

In an alternative embodiment, as shown in fig. 1 to 4, the support 10 may further include a liquid channel 12 and a support main surface 13, the liquid channel 12 is terminated at the support main surface 13, and the support main surface 13 surrounds the liquid channel 12. The liquid channel 12 may be in fluid communication with the reservoir chamber; the support main face 13 forms a continuous annular face at the periphery of the liquid channel 12 so as to surround the liquid channel 12. When the capillary element 20 is flat, its liquid-absorbing surface 21, which is opposite to the atomization surface 22, can be arranged in abutment with the main support surface 13. The capillary element 20 is attached to the support main surface 13 and covers the liquid channel 12, so that the liquid medium stored in the reservoir can be transported to the capillary element 20 through the liquid channel 12 without leaking to a part outside the capillary element 20 through the liquid channel 12. When the holder 10 includes the holder main body 10A and the seal member 10B, the liquid passage 12 may be defined by the holder main body 10A and the seal member 10B together.

Fig. 5 to 8 are a schematic perspective assembly view and a schematic perspective exploded view of an atomizer 100 according to a second embodiment of the present invention. The atomizer 100 of this second embodiment may be substantially the same as the atomizer 100 of the first embodiment, and likewise includes a holder 10, a capillary element 20, a heat generating member 30, and a fixing structure 40. The nebulizer 100 of the second embodiment may be different from the nebulizer 100 of the first embodiment in that: the heating element 30 comprises two electrode connecting terminals 32, a heating part 31 is positioned between the two electrode connecting terminals 32, and a plurality of strip-shaped extending parts 36 are connected to the heating part 31; the holder 10 includes two supporting blocks 14 respectively at both sides of the receiving space 11 of the holder 10, the supporting blocks 14 supporting the electrode connecting ends 32; also, the fixing structure 40 includes a pressing frame 44, the pressing frame 44 having two mating ends 45 and a pressing rod 46 located between the two mating ends 45; at least a portion of the fixing structure 40 presses against the extensions 36, for example, the mating end 45 is snap-fit with the bracket 10, and the pressing rod 46 presses the ends of the extensions 36 against the bracket 10. For another example, a plurality of extension portions 36 may be formed extending from the heat generating portion 31, the extension portions 36 may be arranged in parallel to form a comb shape, and the extending direction of the extension portions 36 is substantially perpendicular to the extending direction of the heat generating portion 31; in some examples, the extension 36 may be bent from the heat generating portion 31 so as not to be located in the extension plane of the heat generating portion 31, so that the heat generating member 30 can at least partially surround the capillary element 20, and thus the extension 36 and the heat generating portion 31 located at both sides of the heat generating portion 31 define a receiving space into which the capillary element 20 can be at least partially received. For example, the extension 36 may be bent from the heating portion 31 at approximately 90 degrees to extend against the side of the capillary element 20 and then bent to be approximately perpendicular to the side of the capillary element 20. A clamping block can be arranged on one side of the supporting block 14 away from the accommodating space 11 so as to be in clamping fit with a clamping groove formed in the matching end 45; the support block 14 may be formed in a hollow structure at a portion corresponding to the middle region of the electrode connection end 32, so that the electrode connection end 32 has a relief space to exhibit a certain elasticity when the electrode column abuts against the middle region of the electrode connection end 32, and the mating end 45 may cover the support block 14. The mating end 45 is snap-fitted to the frame 10 while the pressing lever 46 is moved toward the frame 10, so that the ends of the plurality of extensions 36 are pressed against the frame 10 by the pressing lever 46. Since the plurality of extending portions 36 are pressed against the holder 10, the heat generating portion 31 connected thereto is also restrained so as to be able to closely adhere to the atomizing surface 22 of the capillary element 20.

In an alternative embodiment, as shown in connection with fig. 5-8, the mating end 45 snap fits with the backing block 14 and clamps the electrode connecting end 32 between the backing block 14 and the mating end 45. For example, by configuring the mating end 45 to have a covering portion to cover the supporting block 14, the electrode connecting end 32 can be sandwiched between the end surface of the supporting block 14 and the covering portion, and thus the fixing action of the electrode connecting end 32 is achieved, which can also assist in maintaining the shape of the heat generating member 30 against deformation.

In an alternative embodiment, as shown in connection with fig. 5-8, a portion of the extension 36 is located between the pressing rod 46 and the side of the capillary element 20. The pressing lever 46 may be configured to be located at a side of the capillary element 20 so as to sandwich a portion of the extension 36 perpendicular to the heat generating portion 31 between the pressing lever 46 and the side of the capillary element 20. The pressing rod 46 may be disposed not higher than the atomizing surface 22 of the capillary element 20 so as not to obstruct the flow of aerosol formed at the atomizing surface 22.

In an alternative embodiment, as shown in fig. 5 to 8, the bracket 10 may include a bracket body 10A and a sealing member 10B, the bracket body 10A including the receiving space 11 and the supporting block 14; the seal 10B receives the holder body 10A and is for sealing engagement with a housing defining a reservoir.

It is noted that, in the atomizer 100 of the second embodiment, other details regarding the holder 10, the capillary element 20, the heat generating member 30 and the fixing structure 40 may be substantially the same as those of the atomizer 100 of the first embodiment, and thus, the description thereof is omitted.

Fig. 9 to 12 are a schematic perspective assembly view and a schematic perspective disassembly view of an atomizer 100 according to a third embodiment of the present invention. The atomizer 100 of this third embodiment may be substantially the same as the atomizer 100 of the first embodiment, and likewise includes a holder 10, a capillary element 20, a heat generating member 30, and a fixing structure 40. The nebulizer 100 of the third embodiment may be different from the nebulizer 100 of the first embodiment in that: the heat generating member 30 includes two electrode connection terminals 32 with the heat generating portion 31 therebetween, and a plurality of extensions extending from both sides of the heat generating portion 31 are connected to the heat generating portion 31, the extension direction of the extensions being substantially perpendicular to the extension plane of the heat generating portion 31, and each extension having a portion bent toward the capillary element 20 to constitute a jaw 47; the support 10 comprises two support blocks 14 respectively arranged at two opposite sides of the accommodating space 11 and two side walls 17 respectively arranged at the other two opposite sides of the accommodating space 11, the support blocks 14 support the electrode connecting ends 32, and each side wall 17 is provided with a groove 18 at one side far away from the accommodating space 11; the fixing structure 40 includes the plurality of clamping jaws 47, and the clamping jaws 47 are elastically clamped into the grooves 18, so that the heating element 30 is fixed on the bracket 10. For example, the groove 18 may be a groove parallel to the heat generating portion 31; the tip or near the tip of the jaw 47 may be provided with engaging portions projecting toward the groove 18, and these engaging portions integrally constitute projections parallel to the heat generating portion 31 so as to be able to be stably caught in the groove 18; when the heating element 30 and the clamping jaws 47 are pushed towards the bracket 10, the clamping jaws 47 can slide along the side walls 17 until the clamping parts are clamped in the grooves 18, so that the heating element 30 is fixed on the bracket 10; accordingly, the electrode connection end 32 is moved to contact the supporting block 14, and the heat generating portion 31 is moved to abut against the atomization surface 22 of the capillary element 20 in the accommodation space 11.

In an alternative embodiment, as shown in fig. 9-12, the holder 10 may include a holder body 10A, a support plate 10C, and a seal 10B. The holder body 10A includes the receiving space 11, the supporting block 14, and the side wall 17. The seal 10B receives the holder body 10A and is for sealing engagement with a housing defining a reservoir. The support piece 10C is mounted on the holder body 10A and between the capillary element 20 and the sealing member 10B, for preventing the capillary element 20 from being deformed under pressure. For example, one end of the side wall 17 away from the heat generating portion 31 may be provided with a support groove at the inner side for receiving and supporting the support piece 10C; the support sheet 10C may be made of a hard material so as to have a desired structural strength. Since the seal 10B is generally made of a flexible material and is easily deformed by a pressure, by fixing the support piece 10C between the capillary element 20 and the seal 10B, the pressure can be prevented from being transmitted to the capillary element 20 when the seal 10B is deformed.

It is noted that, in the atomizer 100 of the third embodiment, other details regarding the holder 10, the capillary element 20, the heat generating member 30 and the fixing structure 40 may be substantially the same as those of the atomizer 100 of the first embodiment, and thus, the description thereof is omitted.

Referring to fig. 13 to 16, there are respectively shown a perspective assembly view and a perspective exploded view of an atomizer 100 according to a fourth embodiment of the present invention.
